Stars, Sea, And Smoke From The ISS: Tournament Earth 2021

Isn’t it kind of bananas that for most of human history we’ve been completely oblivious to how utterly environmentally tumultuous the planet has historically been? Before the advent of paleontology, conventional wisdom posited that the earth has more or less looked the same for as long as its been around, but soon enough naturalists like Georges Cuvier came along and said, “well it actually turns out that most of the organisms that have ever existed are actually no longer with us,” thereby introducing the entire concept of extinction to the human race?? Do you realize how coconuts that must have sounded back then?

Not only that, but the more we delved into paleontology the more it became apparent that the Earth has spent so much of its existence (about a billion years) being completely unsuitable and even hostile to life as we know it. A significant stretch of the cosmic timeline classifies our planet as being an oxygen-poor wasteland constantly pounded by asteroids and brimming with active super volcanoes. Even after life on Earth started to stretch out its stubby little amphibious legs we’ve had like five mass extinctions events almost completely fuck it all up (including one known as the Permian extinction which killed off no less than 70% of the planet’s land-based life and 96% of its sea critters). Can you recognize how rare and unlikely it is that out of all the downright catastrophic times any of us could have existed as unfortunate little trilobites or dimetrodons we actually get to exist as humans beings who can learn about this stuff with the help of a scientific discipline that effectively allows us to peer back into the reaches of the past?? Anyway, here’s wonderwall 

Demonstration of the 1974 Arecibo message. The radio message, consisting of seven different parts showcasing human technological knowledge, was sent from Earth to star cluster M13, 25,000 light years away.

(In the actual message the different parts aren’t colored.)

How long do you think it will be before crows discover agriculture?  Surely they have the capacity to learn that seeds dropped in the dirt sometimes make more seeds.  They’re just a hop, skip, and a jump away from civilization, all things considered.

From the invention of wireless to Radio Broadcast to Space

The word radio was coined in 1907 after a decade of furious activity to discover the mechanism for wireless transmission.  A decade earlier, French physicist Édouard Branly coined the term radioconductor to describe a means of wireless transmission.  He based his term on the verb radiate which ultimately came from the Latin word radius meaning the spoke of a wheel, a ray or beam of light.  The word radio was first used by itself in a 1907 article by Lee De Forest. It was used five years later by the Navy to distinguish it from other wireless technologies and entered common usage in the next decade.  Radio technology advanced so quickly that a little over 50 years later on November 16, 1974, scientists broadcast the first interstellar radio message out to the stars, a program that later became known as METI, the Message to Extra-terrestrial Intelligence. To date, only 9 messages have been transmitted by a variety of organizations:

{The Morse Message (1962)}

Arecibo message (1974)

Cosmic Call 1 (1999)

Teen Age Message (2001)

Cosmic Call 2 (2003)

Across the Universe (2008)

A Message From Earth (2008)

Hello From Earth (2009)

RuBisCo Stars (2009)

The first radio message, known as the Morse Message, does not technically belong on this list as the Russians directed the message to Venus, and thus the primary mission was not Interstellar.  The message targets vary in distance from the very short (the majority of targets are under 100 light years away) to the very far, including the Arecibo Message, which targets the M13 globular cluster 24,000 light years away.  

While there have been some dissenting voices who argue that ‘revealing’ our location to enemy or hostile alien civilizations is ill-advised at best, most scientific consensus agrees that due to the physical restrictions on speed and travel (as currently understood) we are in no danger of imminent attack.  While the Arecibo Message won’t reach its target for another 25,000 years or so, the first of the other messages should arrive by 2029.  Other scientist point out that our current terrestrial radio and television broadcasts represent their own METI signal and thus we have no need to fund additional broad- or narrow-cast messages.

A giant Mosasaurus patrolling the prehistoric seas.

All Along The Western Veil

if you think the ocean now is a scary fuck then you haven’t seen the scary fuck that is the prehistoric ocean

so im watching the history channel on youtube (i could tell you so much on short nosed bears rn) but i just finished watching this thing called the mosasaur and its your pretty basic mega water dinosaur, 50 feet long, eel tail, sonar, doesn’t chew its food etc, but then it got dark

these shits were top predators, no competition whatsoever…..except from themselves. the narrator was saying that even though there was nothing to oppose them, they somehow continued to evolve into like fifty 50 different species of this mega predator. And its really cool because it started as a three foot lizard and in just 6 million years it became “the ultimate success story of evolution”. 

they had these weird funky teeth too. not only were they really big and strong like you’d expect but they had teeth in the roof of them mouth cuz they’d slide their dinner down their mouth like a conveyer belt. and since their so big you’d think wow how did no one see them? apparently sea creatures are frickin blind or something bc this megabeasty would just lie on the frickin bottom of the ocean and wait for something to swim up. then it would propel its ass up with this snaky tail and just boosh i ated you

but mosasaurs kept evolving even though they were literally the top predator. why is that?? that doesn’t happen in nature. turns out they were causing themselves to evolve. turns out they’re one of the only species (including humans) that naturally commits murder aka kills their own kind. they’ll bite each others heads until they can get a good grip then one of them snaps the neck. and they didn’t even eat the other guy. they did it. for. fun. (apparently they thrive on violence????)

and im over here going like wtf. but then it got worse. these scary ass motherfuckers began to go anywhere they pleased. they evolved even more and then moved into fresh water. like swamps and rivers. thats terrifying. NOTHING On eARth could stop them. 

Nothing on Earth ;) aka enter the extinction comet

BUT then I learned that even the bigass dino killing comet didn’t even kill the thing. They literally had to starve to death because all of their prey died out. NOPE not them. THey didn’t die out because they’re like dinosaur gods or some shit. EVERYTHING DIED BUT THEM

It’s Dunkleosteus, the Devonian Destroyer! This specimen was discovered right here in Cleveland.
