Slingshot Time Travel With Cosmic Strings


If you have read sci-fi novels or watched sci-fi flicks, then you have heard about cosmic strings. If you have dabbled in physics and astronomy you have probably heard about string theory. But, really, what the heck is a cosmic string? What do they do? Do they really exist? Are they space garbage that can be recycled for another purpose?

You know how Enterprise always seems to encounter some kind of space “anomaly” that causes all sorts of mayhem and the crew doesn’t know what the heck it is? That’s pretty much what life is like for space explorers now. We really have no idea what kind of stuff is out there in outer space. Cosmic strings are just one such anomaly.

Cosmic strings exist. They’re weird. They have different textures. They have walls that define their domains. They’re powerful, possibly containing the energy-mass of our Sun within a tube about one billion of a billionth the size of an atom.  And scientists don’t know much more about them.

The gringa supposes that it’s a good thing that there are not very many of them, as far as we know. Running into such a weird anomaly could be disastrous for astronauts that don’t know what they are dealing with. But some scientists are not above guessing, er, um, theorizing about cosmic strings.

Physicist J. Richard Gott introduced the novel idea of using cosmic strings for time travel. Scientists suspect that these stringlike objects had something to do with how the early universe formed. They are left-over tidbits whose job is all done. Or not. Perhaps they could be upcycled to warp space-time near a black hole making time-travel possible. Is Gott for real?

Cosmic strings are skinnier than an atom. And they are taut, like a rubber band, because they are under immense pressure. So, just like when you launch a spitball by pulling back a rubber band, Gott thinks the same concept could be applied to cosmic strings. But we wouldn’t actually strap a spaceship to a cosmic string and slingshot it across the Universe.

To make Gott’s theory work, he proposes relocating two strings so that they are close together. Because of the great pressure they are under, putting two close together would create a massive gravitational pull on anything that passed near them. The strings would basically suck in a spaceship at such an incredible speed that the crew would experience time dilation.

Time dilation is a fancy way of saying you have changed the passage of time. On Earth, six months may have passed. For astronauts on a cosmic string launched spaceship bound for Mars, the trip might only take one month. They return home to find everyone a couple of years older yet maybe they only experienced the passage of a few months. Yep. Cosmic strings are weird.

The gringa can imagine the rich and the famous exploiting cosmic string travel as the next great fountain of youth treatment. Maybe we could blast across the galaxy our worst criminals on multiple trips. This could essentially leave them for the next generation to sort out. We could find all sorts of crazy uses for time dilation travel.

But Gott’s theory goes further. If the strings were positioned near a black hole, he thinks we could warp time-space and create what he calls a “closed timelike curve”.  This would make true time-travel possible. Currently, time-travel is theorized to only be possible to make trips into the future that are one-way. A person cannot travel back into the past, only forward into the future. But Gott thinks he has found a way to yesterday.

The compounded effects of gravity on a spaceship by two cosmic strings and a black hole could create a loop with the cosmic strings. This powerful loop would propel the spaceship back through time. But there’s a catch. To re-visit a previous birthday just one year prior, a loop of cosmic string powerful enough would need the mass-energy of our entire galaxy. So, basically you sacrifice the life of everyone and everything in the present just to return to life of a year ago. Not so sure it’s worth it. Today doesn’t seem so bad.

Holding Time In Your Hands


What, exactly, is time? A dictionary might define time as continued progress through existence including events from the past, present and future. Or, it might describe time as a form of measurement. But either way, time is not physical. You know, meaning that it has no mass. In other words, it’s not matter that you can hold in your hands, right? Um, the gringa says prepare to have your minds blown. Physicists have gone and done it again. They have created a time crystal. What the heck?


How is a crystal time? Have you ever looked at a crystal under a microscope? Well, check out these images depicting different crystals under a microscopes:


What interests physicists in crystals and how they can be seen as “time” are the repeating patterns and symmetry, called lattices. What is even more interesting is that sometimes crystals will repeat a pattern in several direction yet opt out of other directions. Then there is the curious thing scientists call “symmetry breaking”. That is when there is disruption in a crystal’s spatial symmetry. The reason these unexpected occurrences happen is because a crystal doesn’t exert the same amount of energy in expanding and forming itself in those areas of anomalies.


In case you didn’t catch that “exert the same amount of energy” phrase, let the gringa draw your attention to that. Because that is the most amazing thing about crystals. Because they use energy to grow, a crystal is not just some dead lump of rock. It’s actually a living organic object. Granted, it’s at the lowest rung of the ladder where energy state beings exist, but, in a sense, a crystal is very much “alive”. But what’s that got to do with time?


Well, if a crystal’s physical aspect of symmetry can be seen and disrupted, albeit with a microscope, physicists want to know if a crystal’s temporal symmetry can be made manifest. In other words, convert time into a form of matter that can be touched, seen or held in the hand. Say what?!! Yeah, we’re not talking watch or clock here. We are talking the real, ambiguous, invisible concept of TIME blowing all of our minds by becoming visible and physical.


According to physicists, it’s already been done. The concept is to arrange a bunch of ions in a ring. Then they need to be cooled to bring their energy down to the lowest state possible. Theoretically, this will result in an unbroken ring of ions that are perfectly still.


Now, if the symmetry of the ring is broken, time is disrupted. That is done by rotating the ring. A turn. Kind of like how an orbit around a star marks time for a planet. But, with a crystal, the energy of this rotation can’t be extracted. It has to be conserved in order for temporal symmetry to occur, meaning time repeating itself in consistent cycles. Now, this is the theory. It sounds neat and tidy. Real life is not so simple.


When breaking things down to the quantum level, scientists find that time kind of doesn’t exist. The quantum world doesn’t care about time. When ions are cooled down in a ring on the quantum level, instead of being stationary they spin around and interact. The gringa supposes being friendly in the quantum world is more important than worrying about whether or not you’re late for a meeting. 


So, these cooled, social quantum particles kind of smear themselves about throughout space, willy-nilly, where ever they please. But scientists have discovered that certain things can provoke certain actions, allowing scientists to predict where a quantum particle might show up. This is called “Anderson Localization”, a discovery made in the 1950s.


Scientists today have discovered a particular chain of quantum particles that stick together in their ring pattern. These particles have a magnetization that can be affected by lasers to create certain rates of oscillation. This allowed scientists to measure rates of interaction between the spinning crystals. The scientists zapping these magnetized crystals left them alone to evolve on their own for awhile. They discovered that interactions began occurring at double the rate as before. Because there was nothing driving the particles to interact, since they were being left alone, the only explanation then was that the symmetry of time had been broken. Thus, a time crystal had been created.


It sounds like a lot of hoo-hah to the gringa. What’s the point? What does this mean? Does it have any usefulness? It doesn’t even sound like any of this makes sense. Maybe understanding the properties of this laser affected crystal will help the dear reader and the gringa understand the significance.

  • Changing the frequency of the laser did not change the frequency of the time crystal (remember, all energy beings, humans included, emanate a frequency, including crystals)
  • The crystal’s patterns do not repeat in space, but in time.
  • Once zapped with the laser, the crystals remain in perpetual motion yet contain no energy, which violates one of the fundamental law of physics. Thus time crystals are matter with no energy equilibrium (you know that old physics rule about for every action there is an equal and opposite reaction). Think of it like someone coming along and giving you a push in a swing and you never stop going back and forth.

So, on its most basic level, a time crystal is a form of matter that contains movement that is created without energy. The hope among scientists is that time crystals can become a never-ending energy source and the energy of time crystals can be harvested to power quantum computers. The gringa thinks, then, that “time” crystal is a misleading name. It should be something related to the perpetual energy aspect. Something like “crystal dynamo”. But nobody asked me.

The gringa would really appreciate it, however, if she could use one to power her air conditioner during the Gulf Coast summer season. My electric bills are KILLING me!

A One Way Ticket To Tomorrow – Time Travel


Ever really screwed things up and wanted a do-over? Yeah, the gringa does that all the time. That’s what makes time travel so appealing. But is it possible? Theoretically, sure it’s possible, but only if you want to see the future. To start the day all over again in order to get it right the second time around means travelling faster than light and that, theoretically, is impossible. But, actually, that’s good news. That means a spiteful ex can’t travel back in time and take out your grandfather, thus wiping out your future existence. It also means that adventurers who travel to the future have to stay there (maybe). For a trip to tomorrow, it’s actually relatively easy, according to scientific formulas (although no one’s actually done it yet, I think).

You see, if a person hopped on board their spaceship and zipped away into the cosmos at even a fraction of lightspeed, for a journey of say a year or two, they would return to an Earth that had aged perhaps by decades. So, technically, the galactic pioneers traveled to the future. But Einstein offered another option to travel to the future in the blink of an eye, wormholes.

A wormhole is a time tunnel that connects different parts of the universe. By using the wormhole as a direct route across the universe, rather than taking the long route of flying through the curved mass of space, a person would emerge, within moments, in a completely different time zone, perhaps an entire era altogether, hundreds of years in the future. The furthest a person could then go back in time would be to simply use the wormhole to return to the point they started from. However, a Caltech physicist by the name of Kip Thorne believes that quantum theory suggests that once a person traveled through a wormhole it would collapse behind them. A wormhole to the future might be a one way ticket to tomorrow.

So, if you want to have a time traveling adventure, you just have to find a wormhole. Or go to China. Yep. That’s what the gringa said. Go to China. Interesting reports have been in the news for a few years now about a time travel tunnel in China. Located in Guizhou Province, time travelers can break all the rules and travel back in time. You don’t even need a spaceship. You can use the ancient technology of cars.

It only takes, technically, about five minutes to travel the 400 meter length of the tunnel. However, when drivers emerge on the other side of the tunnel their electronic devices indicate that they have traveled back in time about one hour. However, time is a jealous mistress. It seems to not appreciate being lost and chases down evaders like a jilted lover turned crazed stalker. Once people travel some distance from the tunnel their lost hour catches up with them.

What the heck is happening here? It’s a mystery. One that is absolutely adored by science fiction fans, conspiracy theorists and alien abduction proponents. However, China is not a fan of wacky explanations. They have offered a few boring theories as to why this is happening:

  • A transmitter in the tunnel is resetting everyone’s electronic clocks which reset once again when they receive new GPS signals from a different transmitter after emerging from the tunnel.
  • A localized magnetic anomaly messing about with electronic devices

The gringa doesn’t really care why. It seems harmless and loads of fun. The gringa would like to go back and forth several times, perhaps hundreds of times, maybe thousands just to see what might happen. Maybe I’ll lose a wrinkle or two.
