Otherwise known as a Black Hole
The singularity at the centre of a black hole.
A singularity, made of unimaginably dense material.
A singularity is a point in space-time in which matter and energy are infinitely dense, as at the center of a black hole or at the moment of the Big Bang.
In Physics, singularity is a point at which a function takes an infinite value, especially in space-time when matter is infinitely dense, as at the center of a black hole.
a singularity
A "Singularity" or a "black hole".
There is no "behind" a black hole. A black hole is not a circular disk. The event horizon is spherical, with a singularity at the center. That singularity is an infinitely dense point.
Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.
Good question - some would say that it was a singularity...
A true mathematical singularity is a point, with dimensions of zero.A singularity is a finite mass in zero volume. If it has any length, width, height,or radius, then it may be enormously dense, but it's not a singularity.You're right. I don't understand it either. But that's how it works.
The Big Bang theory postulates that the universe is expanding from an extremely hot and dense state. It does not necessarily say that this state was a singularity - but a singularity would have been consistent with Einstein's relativity theory. If it was indeed a singularity, then it would have been much smaller than a dot; much smaller even then a proton. In fact, it would have had no size at all.
A black hole isn't a hole as such. It is an extremely dense dead star that attracts all matter into a tiny singularity that has a massive density.
