2 Black Holes: What Would Happen?

In summary, when two black holes, one smaller than the other, move towards each other, they would merge into a larger black hole, conserving properties such as mass, angular momentum, and charge. This merger would also produce a significant amount of gravitational radiation, which can be detected by gravity wave detectors.

when there are 2 black holes and 1 is smaller than the other and they move toward each other. what would the effect be? would they combine and become 1 big black hole or would the smaller black hole just disappear?

they would merge into a black hole with larger mass

some energy would escape as gravitational waves
(repercussions of the merger)
but except for that, the mass of the combined hole would
be the sum of the two masses when they were still separate
and far from each other.

Yep, they would coalesce into one larger, black hole conserving properties such as mass angular momentum and charge.

As Marcus said tey would produce a lot of gravational radiation as well, which means that gravity wave detectors are set up to look for just this kind of event.
 

1. What are black holes?

Black holes are regions in space with such strong gravitational pull that nothing, including light, can escape from them. They are formed when a massive star dies and its core collapses under its own gravity.

2. How are black holes detected?

Black holes cannot be directly observed since they do not emit any light, but their presence can be inferred through their effects on surrounding matter and light. Scientists use telescopes and other instruments to detect the gravitational pull and radiation emitted by black holes.

3. What would happen if two black holes collided?

If two black holes were to collide, they would merge into one larger black hole. This event would release an enormous amount of energy in the form of gravitational waves and could also create a burst of X-rays and gamma rays.

4. Can black holes destroy the universe?

No, black holes cannot destroy the entire universe. While black holes have strong gravitational pull, they are not infinitely powerful. They can only affect objects within their immediate vicinity and do not pose a threat to the entire universe.

5. Is it possible for a person to be sucked into a black hole?

It is highly unlikely for a person to be sucked into a black hole. The gravitational pull of a black hole would have to be incredibly strong and the person would have to be very close to the black hole for this to happen. Additionally, the intense radiation and tidal forces near a black hole would likely kill a person before they even reached the event horizon.
