Because there is usually nothing around the spot where the black hole is because the black hole "ate" everything.
there is no aswer to that question, because we know almost nothing about the black holes
A black hole? well scientist are not sure. Black holes is a theory, not proving to be true. But there could be.
No one has ever seen a black hole; so how do we know of them? Well, scientist's measured to movements of planets and saw them all moving toward a force. Now, we believe that there is something in the center of the galaxy that is pulling planets and stars towards it. Scientist's measured that this force is strong enough to decease anything that comes in contact with it. We call this force a "Black Hole". Why is it called a BLACK hole? Well, it is so strong that not even light can escape it.
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
No. The nearest known black holes are many light-years away. Everything we know - everything we THINK we know - about black holes is theoretical. Guesswork.
They know because the effect the black hole has on other matter.
No the singularity is at the core of the black hole.
Don't know which black hole.
technically, we do not know whether black holes are real. theoretically, they are completely possible. scientist believe that they have seen on but are not sure. if real, the largest one originate from larger stars
Since the nearest black hole is many light years away from Earth, it's impossible for a scientist to physically travel to a black hole to study it. Instead, they have to make do with observing the effects of black holes from Earth.
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
Never, because if we can thrive in it than we are not in a black hole
