How long until the sun makes Earth uninhabitable? At the current rate of solar brightening—just over 1% every 100 million years—Earth would suffer this “runaway greenhouse” in 600 million to 700 million years. How far will the sun expand as a...
Why a black hole isn’t really a hole? No, a black hole is not really a hole at all. A black hole is an object just like any other, except that it is extremely dense. This gives it such a high...
How much does time dilate in a black hole? At the point r=rs (this is the event horizon of the black hole), the length of the et-basis vector actually shrinks to zero, which physically corresponds to time dilation going to infinity....
Is time travel possible through a black hole? As you might expect, the possibility of time travel involves those most extreme objects, black holes. And since Einstein’s theory is a theory of space and time, it should be no surprise that...
Does time bend around a black hole? Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in...
Why do black holes speed up time? Time indeed slows down around a black hole according to Stephen Hawking. Now this phenomenon happens because of the super gravitational force of the black hole. By virtue of this enormous force the black...
How long is 1 minute in a black hole? One hour for a black hole observer would equate to 100,000,000 years for a person on Earth. Therefore one minute in a black hole would be roughly 1,700,000 years. How long is...

Can a human survive a black hole? Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home. Aside...
