Did the Chemical Building Blocks of Life Form in Space?
HTML-код
- Опубликовано: 5 мар 2024
- For years scientists thought complex molecules could only be formed on Earth. But what if we did find these kinds of molecules out in space? What if they could be formed not just in and around biology but also in cold, dark corners of the universe? Scientists have wondered if they might have been early seeds for life on earth, or even a stockpile of molecular building blocks deposited onto our planet and others. In 2023, we found ortho-benzyne in molecular clouds, a simple molecule that helps to create more complex molecules.

What’s your favorite molecular cloud? Mine is the Orion A molecular cloud. Oh you don’t just have a favorite already picked out and top of mind? How weird.
The Coalsack! Yeagh, 🤘😫‼️
gotta go with Orion A too :)
Fossil fuels... sounds like that molecular cloud needs some Freedom...
What's the oxygen to come from?
And Democracy.
Thanks, Elaine!

You’re welcome!
Elaine is the best!
“We are made of Star Stuff”
I have been so utterly obsessed with this quote since high school that I’ve dedicated my body to tattoos representing it.
While it is technically true, organic molecules are solely sources from life.
I'm on molecular cloud nine watching each new episode of Reactions, that's for sure!
Thank you, you are making content I've been looking for for years
Thanks, and keep watching, we've got more to come!
Editor Elaine doin WORK this video, props lmao 😂
This is actually pretty cool! And a nice starting point for explaining why we find such complex organic molecules and amino acids in comets?
Fascinating, great video!
Your videos are pretty good
The algorithm should be ashamed of itself for not recommending this more. 3000 views after 24hrs.... c'mon
2:00 saying space is cold isn't 'particularly' meaningful since there aren't many particles there. That's the temperature of the background thermal radiation
the 270k temperature for space is from the cosmological microwave background. the gas clouds them selves tend not to be cold.
Proffesor McGuire is doing some work on the molecules that reside in molecular clouds
Elaine's editing effectively showcased Alex's charisma! I had to rewind the video several times because I was giggling instead of paying attention :)

Okay, who else thinks she's just too adorable for words? :)
Muuuuuurph!!
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Cool!
. . . Could it be that the Creator is behind all these?
The theory on carbon molecule creation is sadly unproven. It would be nice if it was though.

I don't buy this theory of forming organic molecules in space first then rain down on planet. It should be easier to rain down basic carbon then form organic molecules with hotter temp.
Show your working. ;)
