Can light be energy less at a black hole?

Question

Light emitted at an event horizon of a black hole by something falling in will be emittted with an infinite redshift. So zero energy photons are predicted.

Answer 1

Ah. Well a funny thing happens on the way to absolutes. They cannot exist. (Heisenberg's uncertainty principle) even absolute zero has energy. a zero energy photon would have energy. An event horizon 'boils over' with different effects and would evaporate even if nothing can escape t - it does any way. Welcome to the slippery world of mind questions

Answer 2

In short, everything funky dealing with black holes is asymptotic. Yes, directly AT the event horizon, the photons will be infinitely redshifted. But at the event horizon, to our reference frame, all time also stops, meaning the light never moves anywhere, is forever trapped at the event horizon, and won't get to us.

Asymptotically close to the event horizon is another matter however.

Answer 3

No, the visible light from a black hole is not light that has escaped a black hole. Its is the photons from the super-heated gas as it falls into the hole, but is not in the hole yet.

Anything inside the Event Horizon is not visible because light cannot escape it. What you see has not fallen in.

Answer 4

A black hole is nothing but a vaccant place created due to the expiry of a star. after the expiry of a star it explodes and by this explosion a vaccant place is created in the space and that keeps attracting the surroundings. this is b'coz after explosion that transfers some energy into the space which develops a pressure in the surroundings. the exploded place being at low pressure compared to the surroundings the vaccant place attracts everything in its way. so it also attracts the light and the light rays stay within the blackhole but as the light energy is all attracted within that light can't be seen.

Answer 5

When light approaches a black hole, the wavelength increases, turning to red, than to microwaves, until the frequency approaches 0 and wavelength to infinity.

Answer 6

of course light is energy less at black hole,because we know that black hole is the one and only thing which can absorb any thing nearer to it with infinite energy.Any way light is the one and only form of energy from sun.

Answer 7

Infinite actually predicts that the energy will never reach zero. It will approach it but never reach it.

Answer 8

Zero energy photons means frequency, because

E=hbar*(frequency)

So, we are talking about waves with frequency, or no-waves whatever it means! Infinite is VERY slithery term...

Answer 9

it isn't mandatory to commute speedier then mild to "get away" a black hollow as long as you do not bypass the shape horizon(the point of no go back) you'll get away even as travelling at or decrease then the speed of light.
