Chapter 1: What philosophical questions does the episode explore?

0.031 - 8.904 Neil deGrasse Tyson

Nagin, this round had a lot of deep philosophy in it. Ooh, people got juicy. Juicy about time and space and dimensions.

9.304 - 14.331 Negin Farsad

And just things that don't exist and maybe never will, or will they?

15.193 - 49.443 Neil deGrasse Tyson

All that and more coming up on StarTalk's Cosmic Queries. The Grab Bag. Welcome to StarTalk. Your place in the universe where science and pop culture collide. StarTalk begins right now. This is StarTalk. We're going to do a Cosmic Queries grab bag edition. And today I've got with me as my co-host, Nagim Farsad. Nagim. Hello.

49.463 - 55.232 Negin Farsad

Welcome back. Oh my God. So excited to be here. So excited to launch myself into space. Yes.

55.773 - 61.442 Neil deGrasse Tyson

Yes. And you've got all the questions from our Patreon supporters. Yes.

61.422 - 75.097 Negin Farsad

Oh, by the way, just reading through these questions, I have to say, I feel so much better about humanity. There are some extraordinarily smart people out there. You don't get this, you don't know that in your regular life.

75.117 - 79.962 Neil deGrasse Tyson

So you're saying I'm biased into thinking the world is smarter than it actually is because of our fan base.

79.982 - 83.425 Negin Farsad

Because these are not the kinds of things I get from my fans.

83.526 - 88.611 Neil deGrasse Tyson

Just so we're clear. Maybe there'll be some spillage over. So what's your podcast is?

Chapter 2: How do gravitational waves relate to cosmic events?

428.301 - 432.529 Neil deGrasse Tyson

And look at, for example, Artemis just went around the moon and back. You know where the astronauts were?

432.549 - 441.045 Neil deGrasse Tyson

They went up a little bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty, bitty,

441.025 - 447.295 Neil deGrasse Tyson

All the rest of that is fuel. Fuel. And by the time they come back, that's all that's left because they spent all the fuel.

0

447.435 - 448.336 Negin Farsad

Yeah, yeah, yeah.

448.356 - 453.724 Neil deGrasse Tyson

So space travel, ideally, in the future, you would refill that nodes.

453.744 - 460.114 Negin Farsad

And is that just like regular unleaded or like what's in the...

460.094 - 480.537 Neil deGrasse Tyson

Yeah, I mean, it depends on what kind of rocket technology you use. And yeah, give me high octane. I don't know. So the real challenge will be, as we have on Earth, if that's a filling station, you would have to continually supply the filling station. But you can do that on your own time.

480.958 - 481.219 Unknown

Yeah.

481.339 - 500.561 Neil deGrasse Tyson

Right? You can send slow ships to refill. They're not trying to get somewhere on a timed trip. And so there would be this continuous source of fuel brought to them by tankers, space tankers, if I call them that. So there is an occasion for such things.
