Astrophysicist Breaks Down The Origins Of Life | Edge Of Knowledge | Ars Technica

[@edmond4005]

Such an interesting topic and well made video. Thanks Ars Technica! You guys are awesome.

It’s often useful to describe fire when explaining life, and how it has some similarities like respiration, metabolism, and replication but fails the test. Also you should have mentioned evaporating pools. Right now we think that the process of evaporating a pool of water with organic molecules triggers the formation of membranes like cell walls and more complex molecules.

Rudyard Kipling would be proud of you guys. A fantastic Just So story!

5:40 step 1 - Spell Spaceship step 2 - then Boom step 3 - fly to space just like that😆

[@modalmixture]

This was fantastic, I had learned about a lot of this in my college geology classes, but there have been so many developments in the last twenty years that I was unaware of.

[@ReyArteb]

Great presentation.... very thought provoking!

[@sergiodeus3865]

yeah, too bad terraplanist dont think hehe

[@xkrillex]

Such an interesting topic, great video guys!

[@totallyserioustutorials2041]

really well made video! very informative

[@bruce1437]

Very good Paul ☺

[@UltimateTruthsAndWorldviews]

can we have some statistical value for the probability of your theory?

[@deeRay7292]

i love these videos

[@halilzelenka5813]

The legendary Freeman Dyson wrote an interesting book called Origins of Life in which he argues for the metabolism first hypothesis for life’s origin. He proposes a mathematical “toy model” for how this may have worked, but that part was over my head. I think physicists can make valuable contributions to biology because they have the conceptual tools to help to mathematically formalize messy biology. Systems biology is the future of biology

We know this happened, we just don’t how. AKA we just made it up and want you to believe it.

[@noanyobiseniss7462]

It didn't go from dead to alive, there has to be life first before it can be dead.

[@sergiodeus3865]

l always thought the answer was gravity

[@UnbelievablyGauche]

I still can’t believe that everything in the known universe was inside something smaller than the head of a pin. I just recently moved house and let me tell you, only so much went into a 📦

[@avblwd]

You don't believe in sayaance?!

[@pavel9652]

It is a typical rookie mistake to extrapolate a cardboard box to the Planck epoch. The temperature was so high, particles didn't even exist. The fundamental forces were also unified and acted as one. Completely different realm!

[@bentationfunkiloglio]

Love the episode. Not a fan of the over-head camera.

[@thomaswright668]

Not true biologically

[@sentientflower7891]

The only available answer to the question is that abiogenesis is impossible, the RNA World isn't a thing, metabolism without reproduction is a dead end, and reproduction without metabolism is just dead.

[@pavel9652]

Argument from personal incredulity. Also objectively false, since impossible is not the only available answer to abiogenesis.

[@sentientflower7891]

@@pavel9652 yes, it is. This is not a case of an argument from incredulity. It is possible to know precisely what abiotic chemistry in all available environments on the sterile Earth and these chemical reactions do not produce any molecule essential to a living cell within any time relevant to the lifespan of a bacterium.

[@pavel9652]

​@@sentientflower7891 I already demonstrated your statement is false on the logical ground. I am here to learn, not to shoehorn my thinking into a bronze age book, if this is what you are referring to. It is not possible to demonstrate it is impossible. You can't produce ALL available environments with 100% confidence. Nothing is 100% certain. We detected organic molecules including amino acids in molecular clouds in interstellar space and DNA nucleobases in meteorites.

[@pavel9652]

I just responded, but the comment is visible only to me. Ridicules. We detected organic molecules including amino acids in molecular clouds in interstellar space and DNA nucleobases in meteorites.

[@mrbdrm2]

thank god for creating this world thank you for explaining how

[@7thNoodle]

you're welcome

[@aronjanosov9046]

thank the Force for creating this world

[@mhtmane]

4.5 billion years lol how you know this is stubbed thing people need to open theirs eyes

[@pavel9652]

Thanks to the power of evidence, baby.

[@avblwd]

This is just crazy religious talk. This guy believes his ancestor could be a beach hit by lightning.

[@piyh3962]

Unless God came down and wove our DNA together by hand, life has to start somewhere

[@amreshyadav2758]

lol

[@pavel9652]

He has the evidence showing organic molecules spontaneously happen this way and also in space. On the other hand, you believe without any evidence in invisible wizard who did a little hocus-pocus and disappeared into background noise.
