"In a big enough black hole, you could live out the rest of your life pretty normally"
Free falling in your ship and suit waiting for you to be crushed to death... pretty normally
- antimagic 11y agoIt depends on what you mean by "inside" a black hole. If this means "inside the event horizon", well, if the black hole is big enough, you can put yourself in orbit around it relatively easily, you'll just never be able to achieve escape velocity. If you take the Earth for example, a geosync orbit has a velocity of 3.07km/s, whereas escape velocity is 11km/s
- dvdkhlng 11y agoThere aren't any stable orbits within the event horizon of a black hole (due to General Relativity): https://en.wikipedia.org/wiki/Schwarzschild_metric#Orbital_motion https://en.wikipedia.org/wiki/Schwarzschild_metric#Orbital_m...
- antimagic 11y agoNot so, only one of the two solutions is unstable: https://en.wikipedia.org/wiki/Schwarzschild_geodesics#Circular_orbits_and_their_stability https://en.wikipedia.org/wiki/Schwarzschild_geodesics#Circul... Also, this applies only to circular orbits, and does not indicate that a powered ship could not maintain orbit.
- repsilat 11y agoThose orbits are all outside the event horizon. Inside it, all you can hope to do is fall inward as slowly as possible.
- dvdkhlng 11y agoBTW most of what I know about black hole physics is from Greg Egan's novel "Incandescence". Which covers quite a lot of science for a work of fiction (and overall extremely inspiring). http://gregegan.customer.netspace.net.au/INCANDESCENCE/Incandescence.html http://gregegan.customer.netspace.net.au/INCANDESCENCE/Incan...
- nikbackm 11y agoAssuming you still have an internet connection... why not? :) Well, guess TCP/IP is out, but maybe TV and radio broadcasts would still function.
- lexy0202 11y agoLight (read: any electromagnetic wave) cannot escape a black hole beyond the event horizon. Therefore this wouldn't work.
- elemenopy 11y agoCouldn't Anne just beam an electromagnetic wave of TV/radio into the black hole to you, though? Nothing will be escaping the black hole.
- jychang 11y agoJust have Anne toss you DVDs of Game of Thrones from outside the event horizon.
- stcredzero 11y agoNetflix would have to get really creative with their business model to support those subscribers.
- return0 11y agobut it can go in. You can still watch TV
- weavie 11y agoAs the article alluded to we are in many ways free falling and waiting to be crushed to death. It's just we are free falling through time rather than space.
