Can light enter a black hole without physically entering?

« on: June 27, 2011, 08:19:51 AM »

Like, can light just travel in there or can only a physical object enter?

Thanks.
Thanks guys.

I mean, though, can all of our universe's light enter a black hole? I'm confused. Does light enter a black hole just like light reaches us?
I know it's not a literal hole, but figuratively, sure it is. You can't escape it, but stuff can 'enter' it, therefore I'd call it a hole.

Light can enter black holes, but like everything else doesn't get out.

Try looking at it this way --
Everything in the universe, including light, is embedded in space. The shape of space is altered by the presence of mass. A black hole's mass is so strong and intense that space is literally turned back on itself, therefore light embedded in that area of space will "enter" a black hole.

Light enters black holes all the time, hence the reason they are black. The light is actually taken away from the black holes surroundings. In fact black holes even slow down time the closer you get to them.

Black holes pull light and anything else into them that crosses the event horizon for them.

Since black holes warp spacetime, any possible course of action inside that event horizon will result in the particle (light or otherwise) going in to it.

Basically it's like holding up a sheet tightly between two sawhorses and putting a bowling ball (represents the black hole's distortion) on it. Then, toss marbles (particles) onto the sheet. The marbles fall towards the distortion of the large bowling ball when they get close enough to it and they can't escape from it.

No, black holes don't "pull" things in like the common misconception. They are a warping of space itself, so even though light can't be influenced by most forces, it obeys the laws of space like everything else and is pulled inward like anything else. Space is warped fastest near the center, so there is also a point in a black hole called the "event horizon," it is the point where space is being warped inward faster than the speed of light, the point of no return essentially where you can't possibly exit. So no, light cannot escape a black hole.

Just to point out the obvious in case you didn't know, Black Holes are not holes. It was yet another stupid name in science which stuck but has probably caused huge confusion over the years. Another one is Big Bang.

Black Holes suck in everything, even light. That's why we can't see what's in a Black Hole from the outside, because the light will never reach our eyes.

as one of the previous answers black holes never pull a thing as normal, as a normal massive body pulls with its gravity. . but there will be a great time dilation, length contraction and mass elongation in them. hence though things like light don't easily undergo changes.. due to the high gravity and the high effectiveness of the three above changes of relativity, light undergo these changes in it. there will be even space time curvature in it. thus, as the theory of black holes are more confusing we cant trace the perfect path of a light. but we can conclude that light never go to it as it falls on us. the path, the way of travel, all have more differences than that of the light's travel in a normal body like earth.

Nothing physical enters a black hole. Black holes disintegrate all physical things and energy before they are forced into them. Just as some animals, like insects, actually prepare their meals by putrefying them before ingesting them, black holes disintegrate all things before devouring them. Even light is broken down to some of its elemental particles just before entering a black hole. All of the light of the universe cannot enter a black hole. A black hole only pulls things into itself within a relatively small region of space. Light in a sense does enter a black hole just as it reaches us. Just as light reaches our eyes and through it it is converted to chemical and electric signals, so too light and all energy that enters a black hole is converted into the most basic elemental particles to be recycled.

Actually a black hole is a hole. It is a spacial hole, that is, a hole in the energy fabric of space. It is a vortex that leads to the recycling of parts of the universe, especially within galaxies.
