Just wondering cause I've seen lots of movies where light gets suck into the black hole, or maybe I just too many watch movies ?

Yes, this is true because a black hole is simply an imploded star with a density so great that even light does not have enough energy to escape its immense gravitational pull

It is true that at distances very close to a black hole, escape velocity is greater than the speed of light. That is not the same say saying light gets sucked in. And you need to get REALLY close too. If the Sun was a black hole, Earth would be too far away to feel such effects.

yes it is true. The fact is that any object with gravity has an escape velocity. This escape velocity means that this is the required velocity that is need to leave the surface of that object. For example, here on earth to leave the earth and make it into orbit the required escape velocity is around 11km a second. For a black hole the escape velocity exceeds the speed of light (that meaning the required velocity is faster than 300 km/second) , so not even light can escape.

Yes it is true. A blackhole is a super-massive star that colapses infinitely small to a point called the singularity. The whole reason why the are called black holes is because NOTHING not even light can escape the gravitational pull of a blackhole.

No, its true... a black hole is so powerful and so dense that not even light can escape it, and because it doesn't let light escape and it gives off no light of its own, we can't pin point with exact certany where one is... we can only look at different factors and make an educated guess about where they are...

That is what the current scientist tell us, that even light will be sucked into a black hole. Of course, no one has ever really found a black hole, they seem to thing they exist.

Just to clear up a misconception that einstein1351 has about escape velocity --
Escape velocity is NOT the speed that is required to leave the planet's (or star's, etc.) surface and go into orbit. Orbit can be achieved by going at a speed less than escape velocity (less by a factor of sqrt(2), in fact). For example, the space shuttle has NEVER reached escape velocity.
In fact, escape velocity is the speed that is required to LEAVE orbit and continually increase your distance from the earth (or star, etc.) forever. If you travel at escape velocity, you CANNOT stay in orbit--you will just keep travelling farther and farther away from the primary body.

yes the reason why an inquisitive person like you self is because your IQ is three digits and you are curious. if you have watched to many movies, is that bad? there is science stuff out there that explains black holes. do not be pissy. just do the research. a black hole is a nasty celestial enity. in theory, if it comes to play with us , bad things go happen. what we humans have got to accept is that there are are things WE DO NOT KNOW.

Yes within some reason. When a black hole appears in the universe it dosen't suck up all our lamps and candles! LOL!

its not true light can travel through a black hole
