[QUOTE="mps42, post: 2670657, member: 9571"] Here's the way I understand it (which could be wrong). Think of space-time as a huge sheet or blanket. There are things of different sizes and masses on this blanket. Each object creates a dent in the blanket, the more massive the object, the bigger the dent. That's gravity. A "Black hole" is created when a white dwarf star (which is a super dense object) collapses in on itself to the point where there is an incredible amount of mass in almost no space. A virtual singularity. Now, light passes along the surface of space-time but, for our discussion, is't really a "part" of it. Einstein theorized that light, being almost pure energy, traveled at a constant velocty, written as "c". That being the case, it can be effected by gravity (the dents in the fabric of space-time) but cannot be sped up by those dents. If that is true, then a "black hole" is bending light to the point where it keeps going around in circles and never gets out again. Light doesn't "stop". If it did, it couldn't be light, it would be something else. There are ways to detect black holes, by radio waves and radiation and such which means that we can currently either detect something that IS escaping the gravity hole or, in my opinion more likely, we can find them (black holes) by observing the movements of other objects. Now, as for relativity, that's almost a completely different animal... Dangit, now I gotta read "A brief history of time" again... [/QUOTE]
