What Is A Black Hole Nasa

What Is A Black Hole Nasa Space Place 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. A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. the strong gravity occurs because matter has been pressed into a tiny space. this compression can take place at the end of a star’s life. some black holes are a result of dying stars. because no light can escape, black holes are.

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. The black hole would have the same gravity as the sun. earth and the other planets would orbit the black hole as they orbit the sun now. black holes do not go around in space eating stars, moons and planets. earth will not fall into a black hole because no black hole is close enough to the solar system for earth to do that. A black hole is an extremely dense object in space from which no light can escape. while black holes are mysterious and exotic, they are also a key consequence of how gravity works: when a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity.
