Anthropocene #2? Could Be


Let’s travel back in time together, say, about 50 or 60 million years. What might be going on in the wilds of primeval Earth? Are the caveman’s ancestors making stone tipped spears to take down a juicy mammoth for a winter’s worth of dinner? Some scientists think there could have been some pre-historic glassmakers crafting wares. Others say no, no, no, those droplets of glass found in a primordial ancient seabed that is now New Jersey belonged to space aliens who visited long ago and left behind a bit of rubbish. And then there are “those” scientists who stick with the theory of a cataclysmic celestial body impact 10 million years after the dinosaur doomsday comet impact event. This second crash resulted in a smattering of glass droplets in the searing heat. Theory #3 is the story the gringa’s going to go with.

Three excavation sites in New Jersey and another underwater site in Florida have produced these interesting finds. They are shaped like round droplets of water but are actually glass. As the comet or meteor crashes into the surface of the Earth, the space rock is immediately vaporized. Kaboom!

After traveling through the atmosphere on its collision course it is extremely hot. Once vaporized, all of its molten bits are flung will-nilly into the air. As the molten rock bits fall through the air, they take the shape of a droplet, just like any liquid does as it falls through the air. The droplets cool as they fall, hardening into glass the shape of a liquid droplet.

Unlike the comet impact 10 million years earlier that killed off all the large land and sea animals, scientists don’t think this impact resulted in mass extinction of Earth species. What they do think it triggered is a massive climate warming chain of events because of an enormous carbon dioxide contribution to the atmosphere after the impact’s explosion. Over the course of the next 100,000 years temperatures around the world rose by almost 15 degrees Fahrenheit (or 8 degrees Celsius).

Although our modern culture has been conditioned to view a warming climate as disastrous, in this instance it was actually a good thing. After the mass extinction comet 10 million years earlier, the Earth had been plunged into an Ice Age. Warming temperatures triggered the environmental changes that would eventually result in the appearance of early primates and mammals. But the gringa wants to know just where they came from? Where was their genetic material hiding during those cold millenias?

Did they arrive with the glass droplets? Was it a comet made of obsidian or sand or other geological material that can be transformed with heat into glass? Could it have actually been another engineered alien Anthropocene space vehicle sent to re-seed a planet that was dead after the previous catastrophe? Knowing that it will take thousands, even millions, of years for us to transverse the Universe to where an Earth twin planet might exist, might that be why 10 million years passed before re-seeding occurred? Mightn’t it have taken that long for our species of origin to send a probe, check on their colony, receive back probe telemetry, reel in shock at the news, devise a plan and engineer the technology for a 2nd round of genetic material and then deliver the payload? Might all of us alive today be the legacy of Anthropocene Event #2? The gringa says, “Stranger things have happened.”
