Definition of black hole. 1 : a celestial object that has a gravitational field so strong that light cannot escape it and that is believed to be created especially in the collapse of a very massive star. 2 : something resembling a black hole: such as. a. : something that consumes a resource continually. a financial black hole.
black hole. An extremely dense celestial object that has a gravitational field so strong that nothing can escape, not even light. A black hole is formed by the collapse of a massive star’s core in a supernova. See more at star.

4 days ago · The event horizon of a black hole is linked to the object’s escape velocity — the speed that one would need to exceed to escape the black hole’s gravitational pull. The closer someone came to a
Today’s Popular Stories. With no force to check gravity, a budding black hole shrinks to zero volume—at which point it is infinitely dense. Even the light from such a star is unable to escape its immense gravitational pull. The star’s own light becomes trapped in orbit, and …
Ask a dozen physicists what a black hole is, and you may get a dozen different answers – but that’s okay, new philosophy research suggests.
Jan 22, 2015 · Fact 5: Weird time stuff happens around black holes. According to NASA, the black hole is 10 times more massive to the Sun. Nearby is a blue supergiant star that is about 20 times more massive than the Sun, which is bleeding due to the black hole and creating X-ray emissions.
Nov 21, 2018 · Formation. The most common type of black holes are known as stellar mass black holes. These black holes, which are roughly up to a few times the mass of our Sun, form when large main sequence stars (10 – 15 times the mass of our Sun) run out of nuclear fuel in their cores. The result is a massive supernova explosion,
Apr 08, 2019 · The first photo of a black hole is coming Wednesday. What are we going to see and what will we learn? Astronomers will supposedly release the first-ever photo of a black hole on Wednesday.
Into a Black Hole. This means that a black hole contains a lot of information that is hidden from the outside world.But there’s a limit to the amount of information, one can pack into a region of space. Information requires energy, and energy has mass, by Einstein’s famous equation, E = m c squared.
A black hole is what we predict because that’s the only thing that fits the mathematics we use to describe gravity, and there’s too much mass in that general location to be anything other than a
2 days ago · While black holes, by definition, cannot be seen, radiation produced by gas and dust as material is sucked in at enormous velocities and heated to extreme temperatures is visible across multiple
