What happens if a black hole is next to another black hole?
It is possible for two black holes to collide. Once they come so close that they cannot escape each other’s gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. These ripples are called gravitational waves.
Can a black hole pull in another black hole?
Suppose we have a spacecraft just inside the event horizon of a black hole, struggling to escape, but slowly receding into it. Another (bigger) black hole expands until its event horizon includes the spacecraft as well. This pulls both the black hole and space-craft into itself.
Can black holes be gateways?
Scientists use Einstein’s theory of relativity to describe the curving of space, but Einstein’s equations start to break down in the singularities of black holes. So a black hole could be a wormhole, a gateway through space and time.
Can an object come out of a black hole?
Once something falls into a black hole, it can never get out. Although that’s what we conventionally think of, a black hole is more accurately the region of space around this objects from which no form of matter or energy — not even light itself — can escape.
What happens to a black hole when it strikes a companion black hole?
So it is with black holes — after the initial strike of the companion black hole, they continue to vibrate for a long time, gradually losing energy to space until they find themselves back the way they started — isolated spheres of gravity’s total dominance.
Are black holes spheres?
Black holes are also spheres, and are probably some of the most perfectly round objects in the universe. A close second place goes to neutron stars, which are slightly less dense than black holes — they don’t quite have enough mass to collapse down to that level — and light, though extremely distorted by the neutron star, is still able to escape.
How do black holes bend light’s path?
When this was confirmed by observations, the idea of a black hole became obvious. If you pack enough material together, its gravitational pull should be strong enough to not only bend light’s path but also keep it from escaping, just as the Earth is strong enough to pull back much slower objects (like baseballs) to its surface.
How do supermassive black holes form?
Supermassive black holes, meanwhile, form differently – perhaps from the merger of many smaller black holes early in the universe’s history – and grow over the years as they suck in gas from their surroundings. The formation of these objects and their relationship to the galaxy that harbors them is still an area of active research.
