A black hole is a void in space-time where gravity is so strong that no matter or energy can escape the effects of its force.
No - at least no black holes as defined by physics.
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.
Puncture, Tear Or Hole
The term 'black hole' is particularly appropriate in its application to the astrophysical phenomenon of the same name due to the property of the escape velocity exceeding the speed of light. This means that no light or matter escapes a black hole.
A white hole is a theoretical gap in space-time where matter and energy are ejected by its event horizon.
Quasars have a large black hole, called a "supermassive black hole". The term "supermassive black hole" simply means that it has millions or even billions of solar masses.
They're still called black holes. A black hole remains defined as a black hole as long as it absorb everything near them, both energy and matter, including gas.
No non-fictional astronomical body know as black circle. If the question is meant to employ the term 'black hole' in space, what a black hole does is to exist.
No. And the term is "black hole," not "dark hole."
The size of a black hole is a meaningless quantity. The black hole itself, meaning the matter contained within, is infinitely small. However black holes can be defined by their schwartzchild radius which is the size of the event horizon. Look the equation for it up somewhere.
