Cosmic Spas & Outer Space Mineral Mines

Are NASA and other international space agencies interested in creating colonies on the Moon and various other exotic, cosmic locales? Most certainly. However, not for the nefarious purposes of whisking away the highly educated and financial elite in order to preserve the human race from extinction. What they really want to do is exploit the natural resources of these places.

Humans are a hungry species and their appetites include all sorts of stuff from fruits and vegetables to minerals and ores. Many minerals and ores are not only rare, with few deposits in sundry places around the world, but are also finite in their supply. Once diminished, humans will have to find another source. That’s where asteroids and the Moon come into play.

Asteroids are like one of those grab bags you get as a party favor. You never know what’s inside. Although primarily chunks of ice, tar and dust, they also contain scare minerals and metals. For astronaut mining crews, outer space is full of opportunity, kind of like a mechanic entering an auto junkyard the size of Earth. Best estimates to date believe there are hundreds of thousands of asteroids, some nearly five billion years old, of assorted sizes and shapes from the size of a coffee table to hundreds of miles in diameter (Earth, in comparison, is about 8,000 miles in diameter). With such abundance, if humans can overcome the technological and economical obstacles, we may have a seemingly limitless supply of raw materials available.

The gringa wonders what will happen when that occurs? Will space become filled with flag waving asteroids? Considering even a small asteroid could be valued at many millions of dollars in potential minerals, will countries be zipping about space, hither and yon, planting flags on as many asteroids as possible in a territory game of, “Mine! I found it first!”? The gringa is hoping it will be much more civilized than that.

For mining purposes, asteroid’s are classified according to three groups based on light reflection (spectral) analysis. Since mankind cannot yet land on an asteroid and physically take a geological sample or do so with a robotic satellite, scientists evaluate how light reflects off the surface of an asteroid to determine its primary mineral component.

C-type asteroids are dark and carbon based. They are comprised of clay based minerals that have lots of water trapped within the clay. The gringa thinks these could, perhaps become cosmic spas if we could find a way to generate some kind of thermal reaction within the asteroid. Think of it, “Come visit asteroid XP-247 for its relaxing steam baths and mineralized clay body and facial wraps. Just don’t forget your oxygen mask.”

But what about the carbon and other stuff in the clay? Is that any good for anything? Yep. It makes a garden grow lush, thick and plentiful. C-type asteroids rich in carbon, phosphorous and other elements in the fertilizer spectrum could be very valuable as future garden spots. The gringa can now see the cosmic version of the “Hanging Gardens of Babylon” where visitors can also get a soak in the hot springs and a beautifying and detoxifying mineral rich clay body wrap.

I mean, really, we have plenty of clay and carbon and water here on Earth but surely there will be an eager entrepreneur who will see the same potential. Or do we really have plenty of clay, minerals and water on Earth?

The water reserves could very well come in handy. The gringa can see it now – a gravity beam lassos a water rich C-type asteroid and hauls it near Earth’s atmosphere. It then uses transporter technology that has finally been perfected to zap it through the atmosphere, avoiding a friction filled entry that would evaporate up all that precious water. Then, as it approaches fatefully close to a desert region, just before impact a precision laser beam goes, “ZIP, ZAP, ZOOM!” and a lovely shower of water rains down upon the desert with all the pulverized clay and carbon providing rich fertilizer. The desert is soon a fertile oasis. Hey, it could happen. Stranger things already have.

But NASA thinks the real value of water rich asteroids is in using the resource in outer space. By finding a way to mine the water in flight, crews could save billions of dollars by not having to pack this life-support necessity. Interestingly enough, the very thing that humans need to survive, consisting of two molecules of hydrogen and one of oxygen, are the very elements of rocket fuel. (Wow, humans are 60% rocket fuel, or, water, depending on your perspective!). So, astronauts dock their spaceship at a galactic version of Exxon to fill up the tank and top off the water reserves. And while the service station is checking the engine’s oil level and cabin’s air pressure, the crew is freshening up at the nearby spa. Interesting.

So, C-type asteroids can either be Desert-to-Eden conversion sources, hot spring spas, water wells, or rocket fuel depots. Or all three at the same time.Take your pick.

S-type asteroids shine a little brighter than dark, carbon based C-types. That’s because they are rich in reflective metals like cobalt, iron and nickel. If a mining crew is really lucky they could find one with deposits of rhodium, platinum or gold. Scientists estimate that an asteroid about the size of an average bedroom could be packed with well over one million pounds of metals, a tiny fraction being the exceedingly valuable rare ones. Even if mining crews could extract just one hundred pounds of platinum, at about $1000 an ounce, a $100,000 load of platinum would just be the gravy on top of the wealth accumulated from the remaining predominant minerals.

But it may be the M-class asteroids that wars end up being fought over. The wars for oil that we have raging now could very well become wars for M-class asteroids in the future. These asteroids are expected to contain at least ten times the mineral content of S-types.

To make space mining a reality, the mission has to be profitable. With current missions costing in the hundreds of millions, some even billions, an asteroid would have to be massively rich in raw materials. The other option is to develop technologies that are more economical.

Before any of that even matters, current asteroid knowledge needs to be vastly broadened and fine-tuned. We need cosmic cartographers to accurately map the hundreds of thousands of asteroids in outer space. The world needs space geologists that have the technology and knowledge to analyze what minerals each asteroid actually contains. Young students now, who have an interest in a cosmic career, could really have a geology or cartography degree pay off by landing them their dream job.

NASA’s first effort to test their scientific mettle for determining present mineral resources within an asteroid lie with their OSIRIS-REx mission. The goal of “Origins, Spectral Interpretation, Resource Identification, Security and Regolith Explorer” is to return with a geological sample from asteroid Bennu. It is set to launch in September and arrive at the asteroid almost two years later. If all goes according to plan, Earthlings can expect an authentic piece of Bennu to arrive on planet Earth around 2020. (Of course, the gringa is reminded of her favorite piece of motherly advice given regularly to her children in efforts to cultivate a more relaxed approach to life, “The plan is that nothing goes according to plan.”)

In addition to geological studies of Bennu’s raw materials, asteroid re-direction technologies will also be studied. The spacecraft is scheduled to perform an interesting experiment. It is going to give Bennu a gentle, solar nudge. Scientists want to know if sunlight can be used to affect the path of travel of asteroids. I guess the reasoning is that asteroids are too valuable to simply blast into oblivion if Earth happens to be in the way. They would rather nudge them aside then attempt to exploit the wealth they contain.

The most important goals of the mission, however, are to further the development of space mining technologies. They plan to scrape together a two ounce and 4.4 pound geological sample. The spacecraft will then use its state-of-the-art instruments to map the surface of Bennu and analyze its composition. These are the on-board technologies and their purposes:

  • OVIRS (OSIRIS-REx Visible and Infrared Spectrometer) – analyzes visible and near-infrared light to detect minerals, compounds and chemicals within the asteroid.
  • OTES (OSIRIS-REx Thermal Emission Spectrometer) – analyzes infrared light to detect surface minerals of Bennu, determine surface temperature and map the location of water-rich clay mineral deposits.
  • REx (Regolith X-ray Imaging Spectrometer) – analyzes X-ray aura of Bennu’s surface in sunlight to calculate amounts and locations of elements like: iron, magnesium, silicon and sulfur.

To find out if sunlight can be used as an asteroid diversion technique OVIRS and OTES will combine their abilities to study what is known as the “Yarkovsky effect”. When an asteroid absorbs sunlight much of the heat radiates outward and provides a propelling effect. Observations will be made to see if a “man-made” solar heat saturation could result in changing an asteroid’s trajectory.

Most of what will be recorded by the different spectrometers will only reflect what is on Bennu’s surface and within a shallow depth (about half a millimeter). They are not capable of reaching deep within the asteroid’s core. To get a deeper look the spacecraft has a tool that blows nitrogen gas onto the surface that will force minerals up from a depth of about two inches. Even so, it’s pretty obvious that much about Bennu will remain unknown even if the mission is successful in achieving all of its goals.

But, a successful mission will at least tell the world one thing: can mining asteroid’s work? The gringa believes if great wealth is at stake there will be movers and shakers in this world who will make it work one way or another while pocketing a healthy profit in the process.

Chandra & the Jellyfish

IC 443 is more commonly known as the Jellyfish Nebula. What the heck is a nebula? Well, a nebula is a cloud of dust and gas found in outer space. Sometimes, at night, if you find yourself in the perfect spot for stargazing, you may notice a spot in the sky that is brighter or, perhaps, a darker shadow across a brighter patch.

The Jellyfish Nebula is thought to be the gas and dust leftovers of a supernova event that happened in outer space about 5,000 light years from planet Earth. What the heck is a supernova? Sometimes a star suddenly becomes much brighter because of great explosions happening within the gas that it is made up of. When it becomes so explosive and heated that it ejects most of its mass, it has gone supernova. So, in the simplest of terms, a supernova is a star that has exploded BIG TIME.

The gas and dust debris of the Jellyfish Nebula may also be the material that created a strange object found due south of the nebula. This object is officially called CXOU J061705.3+222127. Scientists just call it J0617. These same scientists believe this object to be a pulsar. What the heck is a pulsar? A pulsar is a neutron star that is rapidly spinning around. It also emits pulses of radio waves and electromagnetic radiation.

What the heck is a neutron star? A neutron star usually has a radius less than 18 miles but is densely packed with neutrons. They are most often created when a massive star goes supernova and leaves behind its core. As a massive star runs out of fuel the stage is set for a supernova explosion. When the fuel runs out, the outer layers collapse. When these outer layers come into contact with the core, they then bounce outward creating the supernova explosion. In the end, all that’s left is the core which is now spinning like crazy and emitting pulses of radio waves and radiation.

The post photo of the Jellyfish Nebula has an inset that shows the region surrounding J0617. Scientists are interested in the small ring that appears to surround the pulsar. There is also a feature of something jet-like that passes through the pulsar. The scientists want to determine if this emission is directly related to the pulsar or has a different source. Possibilities are a high speed wind of particles or something like a shock wave.

Nothing definitive has been concluded regarding when the supernova event occurred. Researchers have offered estimates ranging from 3,000 years ago to 30,000 years ago. Needless to say, the scientists have much more to learn about the Jellyfish Nebula and J0617. If the dear reader is interested in more details than what the simple-minded gringa can offer, check out the on-line source “The Astrophysical Journal”.

Research on the Jellyfish Nebula is managed by NASA’s Chandra program. Specifically, Chandra is an X-ray Observatory. It is the most powerful orbiting X-ray telescope in the world. Scientists from all over the world have access to the images generated by this program. The gringa loves how NASA likes to share knowledge and is not stingy with their technology.

Chandra studies cosmic X-rays, or, the effects of matter that has been heated to millions of degrees. High temperatures that create detectable X-rays happen throughout the universe wherever there are strong magnetic fields, powerful forces of gravity, or extreme explosions (like a supernova).

When a supernova happens, charged particles slam into one another. This causes them to produce energy in the form of photons. As photons fly through space, leaving the scene of a supernova event, they actually become light. These are just the sorts of things Chandra has been tracking and recording since 1999 when the Space Shuttle Columbia launched Chandra into outer space.

Chandra has eight mirrors that X-rays slam into, ricochet off, and are focused onto a focal plane that is half as wide as a human hair.  The focal plane captures the image of the X-rays and records the number, position, energy and arrival time. Two spectrometers then analyze the X-ray to determine what form of energy it is and other details of its physical condition.

Chandra is housed in a spacecraft observatory with two sets of thrusters. This observatory was the largest and heaviest payload ever launched by a Space Shuttle, weighing in at liftoff at 50,162 pounds. If you had eyes as powerful as Chandra, you could read a stop sign from twelve miles away. Chandra’s mission duration was originally set for five years. The mission began in August of 1999 and she is still going strong.

Quantum Science Stuff

What word SCREAMS fascinating, mystifying science? Quantum. Webster’s dictionary says, with regard to physics, quantum means the “smallest amount of any form of energy (such as light)”.  NASA is into all sorts of quantum science stuff. Let’s take a stroll through some of NASA’s quantum interests.

NASA has a quantum computing lab. The gringa asks, “What does it do? What does it do?” Located at the Advanced Supercomputing (NAS) facility in California, NASA’s Quantum Artificial Intelligence Laboratory (QuAIL) is studying the computer of the future and how this technology is relevant to the future of mankind. Collaborating with Google and the Universities Space Research Association (USRA), technology is being developed to not only optimize existing computer technology, but to go beyond and create computers that can do what was before considered impossible.

Again, the gringa asks, “Like what?! Like what?!” (You can picture my little dance, hopping from one foot to another, flinging my hands up and down, as I impatiently ask this question). Well, how about “quantum teleportation”? The gringa says, “WHAT?! Are you KIDDING ME?” (now hopping straight up and down on both feet).  The cute little cartoon above illustrates how the technology works.

If visuals aren’t your thing, the gringa will try to convey the concept. Imagine you have eyes that can see things as tiny as itty, bitty particles, which is what makes up everything in our world. Now, consider that there are two particles that, although separated by an incredible distance, they behave as if they are connected (kind of like a married couple). This is called entanglement (yeah, like I said, kinda like a married couple).

What scientists have done with this concept is teleported information about a particle of light over fifteen miles of optical fiber to a crystal “memory bank”. Voila! Quantum teleportation.

However, the gringa is no longer jumping up and down. I’m scratching my head and thinking, “So what!” I mean, it doesn’t really sound like a big deal. It doesn’t even sound like real teleportation to me. I mean, it traveled through a conduit, the optical fiber. I’ve seen enough episodes of Star Trek to know real teleportation means you simply vaporize, POOF, and rematerialize somewhere else. What a let down.

The gringa really doesn’t want to get shot through an optical fiber skinnier than a human hair to make a quick trip to the mall. It would make me feel like a drive-thru bank deposit. I was really looking forward to the POOF and re-materialization thing. I mean, you could strike a pose and really create a fantastic entrance wherever you went.

The “real-life” application of this technology is that it has potential to be used in cryptography. However, not only will it create secure information transmission between computers here on Earth, but also between Earth and spacecrafts. This would be done by imprinting two systems upon each other so that even when they are separated they behave as one system and, thus, unhackable (is that a word?).

So, with a quantum computer system Astronaut Annie can send a love note from Mars to Hubby Harry back on Earth and it would be as securely private as if they were writing love notes back and forth on the same pad of paper across the breakfast table from one another. Okay, the gringa does have to admit that is entirely cool. Hackers terrify me. I’m always afraid they’ll hack into my bank account and get my last five dollars (that’s usually all that’s ever in there, except for payday and maybe one day after, but, yeah, the rest of the time about five bucks).

Now, how this works is like this:  Alice has a yellow photon. She wants Bob to have one just like it. Their friend, Charlie, sends them each a blue photon (these photons are “entangled”, hence the same color).  Now, the rule of entanglement is since the objects are connected, anything done to one affects the other in the same way, as if they were one object. Alice smashes her blue and yellow photons together until the yellow residue dominates the blue. Now, Bob likes the color yellow better than blue so Alice wants to help him change the color of his photon. So, she teleports the information of the color yellow to Bob’s crystal memory bank and the color information imprints on Bob’s photon which now turns yellow.

So, in a nutshell, quantum teleportation is not anything like Star Trek’s device. Does that mean Star Trek technology is impossible? Um, this is NASA, NOTHING is impossible! The concept of the Star Trek transporter is that it changes matter into a signal that can be transmitted to another location and reappears. What this requires is an empty vessel of a corresponding shape waiting on the other end to receive the quantum state of transported information. So, transport a human body? Probably not. However, lay down on a transport bed and beam your consciousness into, say, a robotic version of yourself, could be.

If technology is developed to transport matter through space, what about transporting through time? Is time travel possible? Nope, not unless we get us some wormholes. And, even then it is still only a theory.

Communication and transporting matter is not the only technology that has something “quantum” about it. In medicine there is a device called the Quantum Resonance Spectrometer (QRS). It gathers cellular information from a human body which can be used to predict when a disease may strike based on an analysis of cellular change. The hope is that as this technology is perfected it will be used in preventative medicine. Japanese, Taiwanese and Chinese hospitals are already using the technology in studies of cancer, cardiovascular and heart diseases.

How about quantum energy? Can we say good-bye to oil, coal, and wind power? Maybe. NASA is developing the “quantum dot” solar cell that is flexible, lightweight and absorbs light as if it were a mini-black hole on a sunshine diet. Because of the abundance and availability of solar energy in outer space, imagine the prospects! NASA wants to use these babies on rovers and habitats as well as auxiliary power sources.

The quantum dot not only reduces weight because of it’s tiny, microscopic size that efficiently produces energy, but it also lowers the cost of space travel. The cells can be produced in a process much like ink jet printing. Large batteries that take up a lot of cargo space can become a thing of the past. Can you imagine if cars no longer needed a gas tank? No more oilfields! Hoorah! Hoorah! What is NOT to love about this technology!

So, what is the next thing on the horizon with “quantum science stuff”? How about a world-wide quantum network? If we thought the invention of the Internet was an amazing thing, the gringa says, “We ain’t seen nothin’ yet!”

What’s The Matter With Dark Matter?

The first thing that is the matter with dark matter is that it is not “dark” at all. It’s invisible. It neither emits nor absorbs light.

The second thing that is the matter with dark matter is that the fate of mankind depends on something that science only “infers” to exist. This invisible, theoretical, dark matter holds the existence of the universe in its unseen “hands”.  Scientific principles regarding gravity conclude that without this elusive dark matter every star, planet, and all humans as well, would go flying willy-nilly into outer space.

The third thing that is the matter with dark matter is that if it exists, it is then possible that dark matter creates a parallel, invisible world. All the happenings of another civilization could very well be happening right under our very noses and humankind is completely left out of the loop. How utterly curious. Could this parallel world have a cure for cancer? Does cancer even exist there? Are there political factions squabbling for power? Would such a world even need governance? What a fascinating idea.

These matters are why such a hubbub is made within the scientific community about dark matter. The simplest definition of dark matter is that it is nonluminous (dark, invisible) material that is hypothesized (scientifically assumed) to exist in space. It is thought that it can have different forms such as:

  • Cold Dark Matter: particles that are slow moving when compared to the speed of light and interact weakly with ordinary matter and electromagnetic radiation
  • Warm Dark Matter: particles with properties that could possibly be sterile neutrinos and/or gravitinos, and travel faster than cold dark matter but slower than hot dark matter
  • Hot Dark Matter: (no, not an erotic vampire novel) high-energy particles, moving randomly, and do not interact with electromagnetic radiation

Dark matter is theorized to have been created soon after the Big Bang. Therefore understanding dark matter is critical to understanding and supporting the Big Bang theory. Scientists tend to gravitate toward the theory of the creation of the Universe through the building blocks of cold dark matter after the Big Bang. Structures would grow from the bottom up by smaller objects collapsing because of their own gravity. These collapsed structures would then merge and form larger objects with greater mass. Theorizing that the Universe evolved from cold dark matter collapsing and structural fragments merging resolves the questions of how individual galaxies formed.

Warm dark matter and hot dark matter alone could not hold up under scientific scrutiny as to being the original building blocks of the Universe. Although, it may very well have been a mixed bag of all three forms of dark matter creating structures that ultimately resulted in the Universe as we know it today, such a theory, the Mixed Dark Matter theory, is generally rejected.

The universe that is currently known to man consists of about five percent of matter that is classified as “ordinary”. That means that about five percent of the universe consists of matter with mass that is comprised of atoms, or ions, with a nucleus and protons and neutrons. Cosmologists call these “baryons”. This is the matter humans can see.

If ordinary matter only makes up about five percent of the universe, what is the remaining ninety-five percent made up of? About seventy percent is “dark energy”, or, a theoretical energy in the form of a repulsive force counteracting gravity which results in an accelerated expansion of the universe. Dark matter is thought to make up the balance. It sounds like a recipe straight out of Frankenstein’s laboratory: seven cups of dark energy, three cups of dark matter, and a splash of ordinary matter. Voila, Universe!

Detecting dark matter requires a whole new level of thinking. It does not absorb light. It does not emit light. It produces no detectable levels of electromagnetic radiation. If it’s invisible, and cannot be seen with a telescope, how do cosmologists and astronomers know it exists? Scientists infer the existence of dark matter. When astrophysicists measure the mass of large objects in space, such as stars, they discover discrepancies with regard to gravitational effects. When things just don’t add up, the scientists scratch their heads and ask, “Why do these heavenly bodies generate a gravitational effect that should actually be created by an object with greater mass?”

Questions such as these were being asked as early as 1932 when scientist Jan Oort, a Dutch astronomer, suggested dark matter was to blame for the orbital speed of the stars within the Milky Way galaxy. The following year Swiss astronomer, Fritz Zwicky, also believed dark matter was the culprit for the “missing mass” issue. However, it would take another thirty years before compelling evidence could assist the theory of dark matter in gaining ground in the scientific community.

In the 1960’s and 1970’s, American astronomer, Vera Rubin, was deeply entrenched in her controversial work on galaxy clusters. Working alongside Kent Ford, an astronomer and instrument maker, the pair used his spectrometer design to view the light spectrums of spiral galaxies. Their discovery is called the Rubin-Ford effect.

This phenomenon describes the movement of the Milky Way galaxy relative to sample galaxies. Rubin and Ford theorized that the difference in motion of these galaxies, compared to the Milky Way’s motion, was relative to cosmic microwave background radiation. Rubin then focused on studying the rotation curves of galaxies. This led to the discovery of discrepancies between predicted angular motion of galaxies and the actual observed motion of the galaxies.

The gravity of stars within rotating galaxies is what prevents these galaxies from flying apart. Such strong gravitational forces require immense mass. Rubin’s calculations revealed that such galaxies contained much more mass than could be accounted for by the stars they contained. Attempting to explain this discrepancy became known as the “galaxy rotation problem” and led to the conclusion that dark matter must then exist.

One of Rubin’s observations showed that as much as six times more “dark” mass existed in galaxies than ordinary matter. Her work was highly controversial at the time and continued to be studied, tested, debated and discussed. As more astronomers did their own studies with conclusions that supported Rubin’s assertions, it became well established within the scientific community that most galaxies are predominately “dark matter”.

The result of Rubin and Ford’s work has led to innovative methods of observing galaxies. One such method, gravitational lensing, was used to examine background objects within the Bullet Cluster in attempts to identify the presence of dark matter. Light bends as it travels away from the source to the observer. It is the mass of the observed object which causes the light to bend. The greater the mass, the stronger the gravitational field it creates, thus a greater degree of bending of the rays of light. When light is then bent to a degree greater than would be indicated by the known mass of the astronomical object, dark matter is then assumed to be at play to account for this mathematical anomaly.

Scientists have used gravitational microlensing to conduct large searches throughout the Milky Way galaxy. Astronomical evidence indicates that the universe contains much more matter than what is visible to mankind. Some scientists have even speculated that a parallel world is possible that consists of dark matter and can only interact with the universe as we know it through gravity.

When measuring the velocity of rotation as compared to the distance from the center of a spiral galaxy, such as the Milky Way galaxy, the mathematical discrepancy reveals that the cluster’s mass consists of very little of the ordinary matter objects that are visible. Scientists then suggest that dark matter is concentrated in a halo formation surrounding the visible matter. A dark matter parallel world could perhaps be found in the “halos” around astronomical objects. Since dark matter contains no atoms, like ordinary matter, it cannot interact with ordinary matter through electromagnetics. Dark matter contains no electrical charge. Hence, gravity is the only interactive relationship between dark matter and ordinary matter as the theory is understood at this time.

Spiral galaxies are not alone in containing dark matter. Studies conducted with gravitational lensing reveal that dark matter may very well be present in elliptical galaxies. Within dark halos that surround such galaxies, X-ray emissions indicate atmospheric extensions of hot gas which could support the existence of dark matter. Using X-ray emissions to estimate dark matter existence is achieved by measuring the energy and fluctuation of the X-rays. These measurements can be used to estimate the temperature and density of the gas producing the X-rays as well as the pressure of the gas. A profile of mass can be created by assuming that the gas pressure balances with the present gravity. Discrepancies would then be attributed to dark matter.

As with anything, there are, of course, exceptions to the rule. Globular clusters are thought to perhaps contain no dark matter. Cardiff University astronomers discovered galaxy VIRGOHI21 in 2005 and believe it to be made up entirely of dark matter and absent of any visible stars. So, there is diversity and oddities even amongst the stars.

Dark matter within our very own Milky Way galaxy is, apparently, “wimpy”. Every second of every day millions, perhaps even billions, of weakly interacting massive particles, also known as WIMPs, pass through this globe humans call home. Experiments of detection are vigorously underway searching for these invisible invaders. Because WIMPs do not interact with matter, it is thought that they can be detected by measuring energy and momentum discrepancies as they zip about, collide and annihilate each other. This is one of the studies conducted in supercolliders.

What does the discovery of dark matter mean for mankind? For the scientific community, it is simply another wonderful puzzle to be solved. For the regular person moving through life every day, it might mean a new awareness of the possibility of an invisible world right next to you. Average people who simply want to rise from a chair and cross the room may find themselves compelled to politely mutter the words, “Please excuse me.” These words may appear to be uttered to an empty room containing no one who needs their pardon begged. No, these people are not crazy and talking to themselves, they are simply considering that the room could contain invisible, dark matter co-habitants that find it very disturbing when a human walks right through them without even a, “How do you do?”
