Some are just better big spoons.
THIS IS BLOWING MY MIND RIGHT NOW.
This is called Panspermia, & is a popular theory among many scientists about the origins of life on Earth. That all life here, may have been brought by chucks of other worlds.
antikythera-astronomy, any comments or possible additions?
13,000 years ago a meteorite crashed into Antarctica. After investigation it was believed to have originated in Mars during a time (billions of years ago) when there would’ve been liquid water running on it’s surface.
Dubbed ALH 84001, the meteorite had very strange patterns on it. Actually they were eerily close to what fossilized terrestrial microbes look like. Check it out:
ALH 84001 is unlikely to have brought E.T. life to Earth (even if panspermia turns out to be a thing) but it certainly provides an interesting teaser for what we’ll find on Mars. Let me tell you: the first paleontologist to get to Mars is quite literally going to have a field day.
Amino acids are found on comets. The building blocks for life seem to be abundantly scattered throughout the universe. It’s the common opinion that extra terrestrial life will be found very soon, or direct evidence thereof.
ALH 84001 provided such tantalizing evidence that Mars once had life that then-president Bill Clinton had to give a speech addressing it (of which you can hear, in part, in the movie Contact).
I can say that certain microbial animals have been found to survive in the vacuum of space. Could one survive a ride on a meteor from Mars to Earth?
I’m not really qualified to give an “expert” opinion as I’m not one but you can find books, lectures and interviews with various experts in this specific field if you know who to look for:
- Sarah Seager of MIT is one of the most accomplished. She’s brilliant.
- Seth Shostak, head astronomer of SETI Institute, (Search for Extra Terrestrial Intelligence) is a PhD, many times over published alien hunter (literally his job).
- David Grinspoon who was an astrobiologist working at the Library of Congress.
- Dimitar Sasselov who runs Harvard’s Origins Project.
