I got very interested into this and started reading upon many websites speaking of black holes. I found one theory very interesting. This is the example they talked about:
Say there were two different people in two different ships. Name them "Sally" and "John" so its easy to keep track of who is who. Pretend Sally and John head out to a black hole in space. Sally stops before the Horizon to the black hole, while using a lot of fuel to stay there and not to pass the horizon. But John keeps going past the horizon. As you already know that the black hole moves with incredible forces. Even traveling at the speed of light, you can not escape the black hole once you have entered it. As John gets closer and closer to the black hole, Sally would actually appear to be seeing john Move slower and slower. Lots of people say this is a pure Optical Illusion. What sally is seeing is the image wave of john. But as he gets closer and closer, this image wave gets further delayed because of the black holes force. So with each step his image wave gets further delayed. It is said that the second before he enteres the black hole, his last image wave sent would appear as if he stoped, and froze in time. And Sally (Sitting at the horizon) would never see him enter the black hole because his image wave could never escape the black hole. Nothing can escape it, not even light.
I thought this was highly interesting. So from one view (Bieng johns) he moves at the same speed he always did. But the sally's view watching John seems to be moving in slow motion. Each moment getting slower and slower, untill he appears to litterally freeze in time.
They were also talking about "white holes" which is the exact opposite of a black hole. Black hole=sucks everything in. White hole=blows everything out. And lastly a worm hole, which as many of you know has an enterence in, but an exit in a far distanced place. They say mathmatically speaking if you have a black hole, you have to have a white hole. Than he pretty much contradicts himself by saying just because the mathmatics work on earth, doesn't mean they would apply in space. Hey said white holes and worm holes do not exist (to the best of any scientists knoledge) but mathmatically, they should.
These are just purly interesting points id like to throw out there. What are your views on Black/white/worm holes? Do you think they should exist because mathmatics say they should?
By the way:
I think a lot of the people who view these threads gain false information, not because the post was false, just because they misconstrue the idea of a necessary concept.
First of all, a theory is devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.
So here is a theory about size and infinite:
Our universe is said to be infinite, which makes all distinctive size absolutely irrelevant.
I will elaborate why infinite makes size irrelevant.
Picture your self drawing a perfect circle with chalk on the ground with a radious of about 5 feet. Now start walking precisely on the line of chalk untill you reach the end, not where you started, but the end.
Picture your friend next to you drawing another perfect circle with chalk on the ground with a radious of about 25 feet. Have him start walking precisely on the line of chalk untill he reaches the end, not where he started, but the end.
Because you and your friend would just keep looping(Because there is no end) the size of the circle you are walking around would make no difference whatsoever.
infinite is a unique instance because it embodys no forms of inauguration, intermediate, or cease in it whatsoever.
There is a linegraph drawn out in extraordinary manageable way to be able to fathom the universe with tranquility.
This is called a "KLEIN BOTTLE"

And to help the above poster understand better about the black holes mass bieng compressed over and over.
Picture a trashcompactor with a size of 10 cubic feet.
Now picture a trashcan with a size of 10 cubic feet next to the trashcompactor.
For each bag of trash you put into one, pretend you put the exact amount (A clone of trash) in the other one. Now the trashcan will soon be full, as the trashcompactor will too. So now you compact the guarbadge in the trashcompactor, and keep adding guarbadge to it. But the trashcan is already full, so you leave it be for now. Although the trashcompactor and the trashcan take up the exact same space (10 cubic feet) the trashcompactor can, and will hold far more guarbadge (in terms of mass) than the trashcan. But their is an end to how much trash you can keep compacting in their before it must be emptied, just like the black hole.
The black hole is constantly giving off radiation. Once the radiation runs out, the black litterally evaporates into nothing. (note-This hole process takes much time from when the star dies, to than evaporating. Its not overnight)
This was ment to help you understand that mass is not limited to size by anymeans, as size is very irrelavant when speaking in terms of the universe.
