By observing the stars near the center of the Milky Way, Ghez was able to study the gravitational field distorting their orbits, revealing a supermassive black hole. We now think there are black holes at the center of most galaxies.
WebWhy do some stars end up as black holes? The answer involves the gravity and the internal pressure within the star. These two things oppose each other -- the gravitational force of the star acting on a chunk of matter at the star's surface will want to cause that matter to fall inward, but the internal pressure of the star, acting outward at the surface, will want to … WebAug 21, 2024 · A black hole is a place in space where gravity pulls so much that even light can not get out.
