Can you flash a light into a black hole?

Answer 1

Everything about a black hole is about gravity. As gravity pulls star systems together, the pull of gravity becomes stronger.

Light itself is subject to gravity. Even large planets like Juipter have been shown to bend light.

So simply, the immense light and other energy which must be generated by what is essentially one huge star, is pulled back into the mass by gravity, and we can't see it (which at least saves us from any risk of light blindness). (^_^)

Answer 2

Einstein redeveloped the theory of gravity with his "Theory of General Relativity" and this predicts that light bends when it passes near a body (like the sun).

Near a black hole it bends so much that it cannot escape the area. This is not because light has mass, but because light travels along a path in space-time and mass curves space-time (which curves the path of the light).

Answer 3

A Quasar is just a Galaxy that emits huge amounts of energy, it does not escape a Black Hole. Nothing can escape a black hole, it is the most powerful thing in the universe.

It is said that a Quasar may have a black hole in the center of it, and if it did, it would not technically escape it, but just revolve around it.

For example, our galaxy, a spiral galaxy, is believed to have a massive black hole in the middle and our galaxy revolves around it.

Answer 4

No.

For a start, an object with rest mass CAN'T achieve the speed of light. The objects that do move at the speed of light - such as photons - have no rest mass; they can ONLY move at the speed of light.

Answer 5

For many years, it was universally agreed that no particles or radiation could escape the radius of a black hole, but relatively recently, Professor Steven Hawking has put forward a compelling theory regarding a type of of "black body radiation" as applied to rotating black holes (this theory is now commonly referred to as "Hawking radiation"). Also, jets of high-energy radiation have been observed coming from the poles of rapidly rotating supermassive black holes. These jets may not originate within the black holes themselves, but rather be caused by particles and radiation coming very close to the "surface" (the Schwartzchild radius or event horizon) of the black hole, so while this phenomenon does not appear to originate from "within" the black hole, it is nevertheless certainly caused by the black hole.

Answer 6

To be quite plain, no mater cannot escape a black hole. Not even light its self can escape the gravitational pull of a black hole.

*more info*

Black holes are created when a massive star (about 3-4 times the size of our sun) explode and create a supernovae. The stare will then implode on its self creating a black hole.

The star must be greater than three solar masses, 1 solar mass is 1.98892x1030 .

Answer 7

No. All they do is suck up EVERYTHING in its path and stretches it out to a point where it explodes and becomes absolutely nothing, not even matter!

Yes. At the center of every galaxy (so it is theorized currently) is a super-massive black hole. In galaxies we are able to study, including the Milky Way, there is a lot of star formation at the centers. The things going on in the neighborhoods of these super-massive black holes are very complex, and involve amounts of matter and energy that we can only imagine. Matter does not simply fall straight into a black hole, but it begins to orbit around the hole, more and more rapidly as it gets closer to the event horizon. This causes the ejection of huge amounts of radiation and some matter as well. Even though the black hole may be feeding on a lot of matter, all of this matter and energy is setting the stage for formation of new stars not far away.

When the Andromeda galaxy collides with the Milky Way in a few billion years, the two super-massive black holes will end up colliding, after swirling around each other for goodness knows how long. Gigantic quantities of matter will be taken in by them, but very high energy will also be radiated off of them, and huge amounts of matter will be sent into a frenzy. Out of all of this there will be a period of invigorated start formation. If you can hang on for 4 or 5 billion years, you may get to see some of the action.

Answer 8

To put it rather simply, gravity distorts dimensions (including all spacial, and even time). Because of the absolutely massive gravity of the black hole, the demensions are distorted in such a way that all directions actually lead back to the center. Imaging putting a 50lb wieght on a trampoline, then dropping marbles on it. The marbles would flow to where the the wieght was, despite wherever or in whatever fashion you placed them, or however fast they were thrown, even circling around a part of it maybe for a while. Basically, light=marbles, trampoline=space, wieght=black hole. It doesn't matter how fast the light goes, since once past the event horizon, all directions lead to the center in some way.

Answer 10

Light doesn't have enough energy to escape from the stupendously powerful gravity at the center of the black hole. We don't really understand what is going in the region around a black hole; our physics theories seem to break down there. In the area within which light cannot escape, called the "event horizon", we really don't know what's happening.
