haha no.

http://en.wikipedia.org/wiki/Novikov_self-consistency_principle

If you assume that going "into a black hole" would accelerate you faster than light, then you must also assume via GR that you are now in a Closed Timelike Curve. Novikov shows taht CTCs must also obey the GR Lorentz invariant laws of physics. Ergo, still assuming the FTL scenario, you would be tachyon-annihilated and spit out of the hole as gamma rays.

Which is what happens to shit that falls into black holes.

Becasue It only models Newtonian gravity. When they change the engine to reflect general relativity, I'll reinstall. And test my warp drive ship.

I like how photons don't have mass in the Standard Model, but in General Relativity light is affected by the curvature of spacetime which means it must interact with the gravitational force. So the Theories tell us that photons interact with the phenomenon of gravity and yet have no real energy density or mass in the traditional sense.

Sounds like a theoretical crisis to me.

Ok /sci/ducks I know this might be over your head, but I would appreciate any legit help that may occur.

I would like model a non-commutative version of the pseudo-Riemann Einstein tensor, so that I can see what happens when the Schrödinger probability density "gravitationally" "curves" a 2-dimensional Hilbert space consisting of coordinate time on one axis and imaginary wavefunction amplitude on the other axis. Hopefully I can substitute the Einsteinian metric tensor for the Dirac matrix from the Dirac equation and call it a "Dirac tensor".

How do?

Ok I'll accept that. energy-momentum tensor and all that.

So then what the fuck is mass?

this thread is now about what the fuck mass is.

I thought sci was about FTL threads. But granted, the FTL threads usually become quantum gravity threads, which further devolve into people yelling at each other they they "don't understand relativity", which is usually supplemented by troll science claims

first of all, wtf is the "A-theory of time?" and second of all,

>the idea that the hypersurface of homogeneity is the privileged frame, which determines absolute temporal and spatial measurements, has been part of graduate textbooks on General Relativity or cosmology going back to the 20s

lol no

FUCKIN' GENERAL RELATIVITY HOW DOES IT WORK

Pic related, its a graphic representation of the Trollzschild solution to the Einstein faggot equations

Spacetime always envelopes matter, dipshit. It's not a trampoline, its a 4-d jello. That spacelike diagram in op's pic could be "not enveloped" from another reference frame.

ITT: a post about the nature of gravity spawns a thread about the hidden-order/veil-of-ignorance argument for the existence of a god, because some creationistfag doesn't think that humans weight anything because their souls don't weight anything, and also that the earth rotates around it's axis so that god could let us see the whole sky

I hate you, /sci/

Black holes don't real. prove me wrong.
