Will light falling into a black hole accelerate Why or why not?

It would not accelerate because it does not go straight in.As it turns out ,nothing does.Everything that goes in spirals in , like water going down a drain.
If space time is the tub or sink ,the black hole is the drain and the matter (in this case light)is the water,the water spirales in.It would look to an outside observer like the light is turning red. This is because it decelerates.If light sped up it would be able to escape the black hole and we would see the black hole and it would not be a black hole.

How would falling into a black hole feel like?
You would die quickly, either before, or after, falling into the black hole, depending on the mass of the black hole.
How do scientists know black holes exist if these objects don't emit visible light?
They don't directly emit light, but anything falling into them will emit strong electromagnetic radiation - due to the acceleration of the matter falling into the black hole. Also, the black hole attracts all matter near it.
What happens to the frequency of light emitted from the vicinity of a black hole Why and What happens to the frequency of light falling into a black hole What would you call this effect?
When light is traveling away from a black hole, its wavelength becomes longer. This is called blue-shifting. If it's going in, the wavelength becomes shorter, which is called red-shifting.
Can you see a black hole in outer space?
Not directly. If large amounts of matter is falling into the black hole it will heat up and glow brightly. You could also potentially see the distortion of light around the black hole, but you'd have to get pretty close to see that.
Is a black hole visible?
For most purposes, no, black holes themselves are not visible. Black holes absorb everything near them, including light. Light needs to originate from an object or strike an object and reflect from it and to your eyes in order for you to see it. Light that enters a black hole can never leave. Since black holes do not emit light or any form of electromagnetic radiation, it is impossible for astronomers to observe them directly. However, matter falling into a black hole can become superheated and emit light and x-rays before falling past the point from which nothing can return. We can detect this radiation. Theoretically, you could also see the event horizon of a black hole if you got close enough; it would appear as a completely black sphere against a background of stars. The light from stars behind the black hole would be highly distorted, as can be seen in the image above.
What observations do astromomers use to infer the existence of black holes?
Matter falling into the black hole will emit X-rays. The matter is subject to tremendous acceleration before falling into the event horizon.The black hole will still attract surrounding objects, which may be in orbit around it. In some cases (especially the supermassive black hole in the center of our galaxy), a black hole is the only reasonable explanation for the observed orbit (a mass of about 4 million solar masses, and a diameter of a few light-hours at most).Also, observations of gravitational lensing. The black hole's gravity will distort the light coming from objects behind it.A black hole can not be truly seen but what astronomers do look for manly is the event horizon it is the very edge of the black hole ... the event horizon is noticed when light droops and bends in to the black hole ...
How does light calculate in a black hole?
I am not aware of light calculating anything in a black hole.
What is the brilliant light coming from a black hole?
if there is light surrounding a black hole it is normally from material entering into the event horizon of the black hole.
Can you make light circular?
Only around a black hole. There is a sphere around every black hole where light orbits the black hole.
How can you in notice a black hole in the space if it absorbs all the light?
we can notice by the effect it causes on the nearby stars. A star which is near a black hole revolves around it and when it is closer to a black hole ,it revolvles faster and it revolves slower when it is farther away from a black hole.Secondly, we can notice a black hole by the space distortion it creates. Thirdly, we can notice it by finding the amount of gas of nearby stars falling into the black hole
If light can be pulled into a black hole that suggests mass What is the weight per square meter?
light has no mass and therefore no weight. Light cannot be "pulled" into a black hole. The escape velocity from a black hole is greater than the speed of light, so no light can escape from a black hole. Spacetime in the vicinity of a black hole is greatly distorted by the hole's gravity, and light may travel along curved geodesics that intersect the black hole. But it is not pulled in.
How does a quasar work?
A quasar is believed to have a supermassive black hole at its center. The radiation is emitted outside the black hole's event horizon - from matter that is falling into the black hole.
