Adam Frank: evaluation

Transcript context

…So, you think it’s not possible to travel fast than the speed of light? I wouldn’t say that. I wouldn’t say that, but what I think, if you look at the physics, we understand, every possibility for faster than light travel really relies on something that doesn’t exist. So, the cool thing is Einstein’s field equations, you can actually play with them, the equations are right there. You can add things to the right or left-hand side that allow you to get something like the Alcubierre drive. That was a metric that showed you like, “Oh, it’s a warped bubble.” It’s a warping of spacetime that moves through spacetime faster than the speed of light. Because nothing can move across space faster than the speed of light, but spacetime itself can move faster than the speed of light. But here’s the problem with all of those proposals is they all need something. The thing you added, the little fictional term you added into the equations is something called exotic matter and it doesn’t exist. It’s really just something we dreamed up to make the equation to do what we wanted them to do. So, it’s a nice fiction but really right now, we live in this weird moment in history of the great acceleration where the technology we used now is completely different from the technology we used 10 years ago is remarkably different from the technology from 100 years ago. But I remember playing Assassin’s Creed where everybody’s like, “What is it, it’s 1200?” And everybody’s like, “Stab, stab, stab.” And I was like, “Yeah, it’s a great game.” And then I got Assassin’s Creed II and it was 300 years later and everybody’s like, “Stab, stab, stab.” And it was like 300 years and the technology hadn’t changed and that was actually true for most of human history. You used your great-grandfather’s tools because there was no need to have any other new tools and you probably did his job. So, we could be fooled into thinking like, “Oh, technology’s going to go on forever, we’re always going to find new advances.” As opposed to sometimes things just flatten out for a long time. So, you have to be careful about that bias that we have living in this time of great acceleration. Yeah. But also, it is a great acceleration and we also are not good at predicting what that entails if it does keep accelerating. So, for example, somebody like Eric Weinstein often talks about we underinvest in theoretical physics research. Basically, we’re trying too hard for traditional chemical propulsion on rockets versus trying to hack physics, warp drives and so on.…
