What Is A Black Hole In Simple Terms For Dummies Black holes are dying stars. a black hole is formed from a dying star. but, not just any star. it has to be massive. at least 20 times the mass of our sun, which is already enormous. as the star goes through the process of its violent death, all of its material is crushed down so tightly that processes and physics, as we know them, break down. A black hole’s gravity, or attractive force, is so strong that it pulls in anything that gets too close. it can even swallow entire stars. nothing can move fast enough to escape a black hole’s gravity. this includes light, the fastest thing in the universe. that’s why we can’t see black holes in space—they've gobbled up all the light.
What Is A Black Hole In Simple Terms For Dummies A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. a black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. matter and radiation fall in, but they can. Nothing is darker than a black hole. a black hole is an area of such immense gravity that nothing—not even light—can escape from it. black holes form at the end of some stars’ lives. the energy that held the star together disappears and it collapses in on itself producing a magnificent explosion. here’s where things get crazy. A black hole can be formed when a huge star uses up its fuel. a star is normally a huge ball of a gas called hydrogen, which serves as fuel for the star. the star constantly changes the hydrogen into other gases and in the process makes energy. the energy pushes outward. at the same time, the star’s gravity pulls inward. A black hole is a place in space where gravity pulls so much that even light can not get out. the gravity is so strong because matter has been squeezed into a tiny space. this can happen when a star is dying. because no light can get out, people can’t see black holes. they are invisible.

The black hole is 6.5 billion times more massive than the sun. this picture was the first direct visual evidence of a supermassive black hole and its shadow. the ring is brighter on one side because the black hole is rotating, and thus material on the side of the black hole turning toward earth has its emission boosted by the doppler effect. Transcript. [narrator] black holes are among the most fascinating objects in our universe, and also the most mysterious. a black hole is a region in space where the force of gravity is so strong, not even light, the fastest known entity in our universe, can escape. the boundary of a black hole is called the event horizon, a point of no return.
