#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Yes.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

It would be great because they help to understand the parameters, maybe formulate, maybe quantify, create models, but ultimately you need to experiment.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Yeah, absolutely.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

That's why there's definitely a lot of benefit to those models, predictions, because they at least help the experimentalist to come up with the priors and parameterize things better, maybe eliminate very obvious dead ends early on, given that experiments take such a long time and it's a huge investment.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

And no one's a better experimentalist than nature, so...

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

You really want to make me sad.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

You're not going to win.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

So the proposition I made, I like to think of it as protospermia rather than panspermia.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Because it's even more proto-state than acknowledging.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Because in panspermia, you still have a cell.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

You still have something that is very, even a cell to me would be very Earth-like.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

I'm talking at sub-cellular level in the proposition of spreading chemistry.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Exactly.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

It will be more like the fertilizer that is well-adopted and compatible with that planetary body.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

In panspermia, you're still imagining either an entire bacteria or microbe or a cell or something that is DNA, which is still terran.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Yeah.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

But in terms of panspermia, I mean, obviously, there's going to be always room for those sort of discussions, or there will be...

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Those discussions will always be present, I think, in any life in universe debates.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

But the problem I have with panspermia is that it removes the problem from the planet to somewhere else.

It makes it
