first question
From what i read Hawking radiation is a particle and ant particle created on the event horizon of a black hole, one particle is pulled into the black hole letting the other escape, why does the one outside of the event horizon escape instead of both being pulled in? It would still...
I guess unfamiliarity with terms is preventing me from stating my question clearly. Let me try again.
Begin, box ( spacecraft ) stationary, in free fall. Inside box, against one wall is a precompressed spring with a small mass against the end of the spring opposite the wall.
Release spring...
If some of the momentum (kinetic energy) that would normally cancel the spacecraft s momentum in the other direction was converted to heat (with the sandbag) it would seem that energy would be conserved even though momentum would not be conserved.
that was the original question, is momentum...
Of course energy is conserved, and if the collisions at each end of the craft are equally and perfectly elastic, then the center of mass will be stationary and the craft's hull will oscillate opposite to the sprung mass inside. But if some of that energy is converted to heat at one end how can...
Homework Statement
Spacecraft, with vacuum inside, in free-fall, contains a small mass captured against a fully-compressed compression spring against one wall of the craft. Release the spring and mass. Mass is accelerated by recovering spring (elastic potential energy turning to kinetic)...
so what you are seeing is actually the past? And if it only exists in the future and is not in the time of now what is the gravity that pulls you towards the schwarzschild (i hope i spelled this right) radius from?
Is the gravity so strong i can pull through time?
due to quantum theory, not all...
whatever direction you face will be towards the singularity, so if you threw something backwards and forwards at the same time would you actually be throwing them the same way?
And what would happen if (theoretically of course, there is no way to actually do this) you reached the center of the...
why can't a photon escape a black hole? i think it is because the photon is red shifted away to nothing, if this is true, it would be possible to create a photon that would be energetic enough that a black hole would not have enough time to red shift it away to nothing, unless there is some...
