- Carroll's book that there were people who opposed this the supercollider because they felt it would create a black hole oh yeah yeah oh yeah yeah oh we could never prove that they were— The Big Picture
- this transition black hole you don't have to go to infinity like a lot of my colleagues love to do right now why because they after all always assume— PSW 2442 Quantum Gravity | Carlo Rovelli
- we talking about? We're talking about some kind of causal black hole, something that's, you know, quintessentially inert and you can never see it because you can only see the— Your Brain Is a Prediction Machine, Not a Processor — Karl Friston
- fly by. It's not like it was speeding up for the crewmate because everything is time as it always is. It's always the time that you experience. But relative to the clock near the black hole, which— Live Q&A with Brian Greene | World Science Festival
- issue that people have argued about has to do with Hawking radiation that you may have heard of, which is this idea that when you have a black hole, it can cause, and we believe it will— Live Q&A with Brian Greene | World Science Festival
- Brian: But part of what was alien too, I presume, was there are two different narratives, two different stories that you need to tell if you're watching something fall to a black hole versus the story that will be told by the individual, unfortunately, who is passing into the black hole. Can you just take us through that because that's also deeply unfamiliar?— Greatest Mysteries of Gravity | Brian Greene & Kip Thorne | World Science Festival
- Kip: He's very deep and he's a superb physicist in all aspects of optics, ever so much more than I know. And so I provide the equation that we need to do a propagation of light, say from the accretion disc hot gas going around a black hole, propagation of light around a black hole and down to an IMAX camera. And it doesn't work because he analyzes it, and he figures out the problem is that if you have two adjacent pixels— Greatest Mysteries of Gravity | Brian Greene & Kip Thorne | World Science Festival
- at that solution, people often describe it as it sows the seeds of the own destruction of general relativity because at the center of this solution, which we now call The Black Hole Solution, there are things that become infinite. Invariant things that can't be done away with by a coordinate transformation. Curvature invariance and so forth. So you must encounter those in some form and what do they look like in your language and what do you do about them?— Can space and time emerge from simple rules? Stephen Wolfram thinks so. | World Science Fe
