The Day the Dinosaurs Died
A young paleontologist may have discovered a record of the most significant event in the history of life on Earth.

If, on a certain evening about sixty-¬six million years ago, you had stood somewhere in North America and looked up at the sky, you would have soon made out what appeared to be a star. If you watched for an hour or two, the star would have seemed to grow in brightness, although it barely moved. That’s because it was not a star but an asteroid, and it was headed directly for Earth at about forty-five thousand miles an hour. Sixty hours later, the asteroid hit. The air in front was compressed and violently heated, and it blasted a hole through the atmosphere, generating a supersonic shock wave. The asteroid struck a shallow sea where the Yucatán peninsula is today. In that moment, the Cretaceous period ended and the Paleogene period began.

A few years ago, scientists at Los Alamos National Laboratory used what was then one of the world’s most powerful computers, the so-called Q Machine, to model the effects of the impact. The result was a slow-motion, second-by-second false-color video of the event. Within two minutes of slamming into Earth, the asteroid, which was at least six miles wide, had gouged a crater about eighteen miles deep and lofted twenty-five trillion metric tons of debris into the atmosphere. Picture the splash of a pebble falling into pond water, but on a planetary scale. When Earth’s crust rebounded, a peak higher than Mt. Everest briefly rose up. The energy released was more than that of a billion Hiroshima bombs, but the blast looked nothing like a nuclear explosion, with its signature mushroom cloud. Instead, the initial blowout formed a “rooster tail,” a gigantic jet of molten material, which exited the atmosphere, some of it fanning out over North America. Much of the material was several times hotter than the surface of the sun, and it set fire to everything within a thousand miles. In addition, an inverted cone of liquefied, superheated rock rose, spread outward as countless red-hot blobs of glass, called tektites, and blanketed the Western Hemisphere.

Some of the ejecta escaped Earth’s gravitational pull and went into irregular orbits around the sun. Over millions of years, bits of it found their way to other planets and moons in the solar system. Mars was eventually strewn with the debris—just as pieces of Mars, knocked aloft by ancient asteroid impacts, have been found on Earth. A 2013 study in the journal Astrobiology estimated that tens of thousands of pounds of impact rubble may have landed on Titan, a moon of Saturn, and on Europa and Callisto, which orbit Jupiter—three satellites that scientists believe may have promising habitats for life. Mathematical models indicate that at least some of this vagabond debris still harbored living microbes. The asteroid may have sown life throughout the solar system, even as it ravaged life on Earth.

…DePalma said, “It’s like finding the Holy Grail clutched in the bony fingers of Jimmy Hoffa, sitting on top of the Lost Ark.” [ :blink: ]

Exhibit A:

Viruses, ET and the octopus from space: the return of panspermia

The peer-reviewed journal Progress in Biophysics and Molecular Biology recently published a most remarkable scientific paper. With 33 authors from a wide range of reputable universities and research institutes, the paper makes a seemingly incredible claim. A claim that if true, would have the most profound consequences for our understanding of the universe. Life, the paper argues, did not originate on the planet Earth.

Beyond this, the model also postulates that various epidemics are caused by the arrival of viruses from space and that extra-terrestrial retroviruses drove the Cambrian explosion.

Not to mention that the octopus might well be an alien.

Instead of dismissing panspermia out of hand, perhaps then, we should just wait for the discoveries that future space probes might bring. Evidence, as always, will be the ultimate decider.

Exhibit B:

Interstellar Influenza? Space Viruses Could Reveal Alien Life

Viruses straddle the definition of life. They lack the machinery to reproduce on their own, so they must infect a host cell and hijack its machinery. This has led to decades of debate over whether viruses should technically be considered living.

But for the review authors, viruses' reproductive methods are enough. Indeed, "when one considers the whole virus replication cycle, it comes close to NASA's working definition of life: 'a self-sustaining chemical system capable of Darwinian evolution,'" the review said.

Semantics aside, if scientists were to identify a virus in space — on a meteor, perhaps — very few people would claim the discovery was not evidence of life in space, the authors wrote.

"What is life? Are viruses alive? If we find viruses [in space], is it indicative of life? And would this be life as we know it or life as we don't know it?" Stedman asked. "We're hoping to get people thinking about these types of definitions."
