34:19acids are the left-handed form. Okay? It just is what it is, right? >> Because and there there's actually this is a big um mystery in like the origin of life. Like how does everyone like in the same you know you could have picked two and everyone's picked one, right? And it's probably because whatever primordial ancestor was the first, you know, primordial origin of life on Earth picked the left-handed form and then as everyone descended from that, right, the DNA became left-handed, the proteins became left-handed, the glucose that comes out becomes a certain-handedness, everything becomes that handedness. And
35:01so you can make stuff in the lab, >> right? That is both, right? You can you can have both kirality in the lab, but when it comes to biology, we're always going to make onehandedness. >> That is fascinating. >> So So if if we're talking now, we're DMing this this alien, right? >> Yes. >> And we're like, make a bunch of C6H1206. >> Yes. >> He's actually going to be like, I'm getting both. I'm getting stuff that's going to the right and to the left. And we're going to be like, okay, which one can you eat? >> Uh, right. He'll be like, "Oh, maybe maybe he could eat the the ones that are left because the the primordial life on his planet >> was the other hand, right? So, that's
35:43not going to work. >> It's not going to work." >> I thought that was such a cool little >> That's very, you know, and [laughter] it's it's such a simple question that has such deep implications in terms of actually trying to >> Yeah. >> facilitate. It's again, it starts off like a silly go like, "Oh, how can you tell an alien left versus right?" Yeah. >> But there's actually some really deep fundamental. >> There's deep physics here. >> Yeah. Yeah. Yeah. >> Can you >> Yeah. Can you >> The question is, can you >> can you >> can you without sending him a photo? >> Right. >> Right. If I send him a photo, it's easy. >> But via strictly >> via just strictly I need you to do stuff. Yeah. >> There. >> Yes. In order to illustrate left versus
36:24right. >> Left versus right. Can I do this? Right. So it's still failing even if we do these uh this this chemical sort of
