4/4: Impact: How Rocks from Space Led to Life, Culture, and Donkey Kong Hardcover – by Greg Brennecka (Author)

https://www.amazon.com/Impact-Rocks-Space-Culture-Donkey/dp/0063078929/ref=tmm_hrd_swatch_0?_encoding=UTF8&qid=&sr=

Impact argues that Earth would be a lifeless, inhospitable piece of rock without being fortuitously assaulted with meteorites throughout the history of the planet. These bombardments transformed Earth’s early atmosphere and delivered the complex organic molecules that allowed life to develop on our planet. While meteorites have provided the raw materials for life to thrive, they have radically devastated life as well, most famously killing off the dinosaurs and paving the way for humans to evolve to where we are today.

As noted meteoriticist Greg Brennecka explains, meteorites did not just set us on the path to becoming human, they helped direct the development of human culture. Meteorites have influenced humanity since the start of civilization. Over the centuries, meteorite falls and other cosmic cinema have started (and stopped) wars, terrified millions, and inspired religions throughout the world.

This is CBSI in the world. I'm John Bachelord with the author Greg Brannica, who is a cosmochemist. His day job.

0:37.0

He's an author, impact, how rocks from space led to life, culture and Donkey Kong.

0:42.0

We see the seas on the world's world life. Because we've established that there's a way of saying what happened before the moon and after the moon.

0:50.0

Right now, Greg, I need a definition. What is a complex organic molecule?

0:56.0

Well, a complex organic molecule is a molecule that contains carbon, usually some hydrogen bonded to it.

1:04.0

And then when it becomes complex, I guess it gets a little bigger than just carbon and hydrogen.

1:10.0

So, you know, the definition is quite fuzzy about what complex means. But it just means something that's got a little bit more to it than just carbon and hydrogen, I guess.

1:19.0

And the reason we're looking at them is because the word organic is highly suggested.

1:25.0

However, we don't have the, at this point, we don't have the formula that we need to put together organic molecules, amino acids and meteorites.

1:38.0

But it would appear that you have the elements for it. That's from reading your reporting. You don't go any farther than that. You just say that you have these elements, which is why the question is where they hear on earth when the earth was built.

1:53.0

Or did they come from meteorites? But Greg, you've taught me that earth and Mars and the asteroid belt and the meteorites that fall upon us and even the commas that come in from your cloud were all made of the same thing. Is that correct?

2:08.0

Essentially, yeah. So, you know, different elements are going to be concentrated in different areas.

2:13.0

But yeah, we're all kind of made from the same blended material from the formula to the cloud. So, yeah, you're right. We're all kind of the same, the same stuff is just in different ratios.

2:25.0

So, I have the page from Greg's book where he gives us a chart of present and meteorites, amino acids, nucleotides and other selected essential molecules for life.

2:36.0

This is a pretty long list and you say that it could be a lot longer and you're working out and all the time. So, where are we going with this? We have rock heated rock. This is the earth recovering from the collision with the Mars like planet.

2:51.0

And we have, all right, let's, let's veer away from that pursuit to go for water. Where does water come from? We can presume there wasn't much left after that collision.

3:02.0

That could be true. There's actually some evidence to suggest that water may have existed prior to that and then was maybe liberated during that moon forming impact and then basically settled back on the planet afterwards.

3:15.0

So, water doesn't necessarily have to be delivered from, you know, the or cloud or from beyond Jupiter's orbit or anything like that.
