Yes. It has happened before. There are supermassive black holes, and they got that way in part from combining with other black holes. And just as it has happened before, it will happen again. It is likely happening now somewhere in the universe. A small black hole is circling a very large one near the event horizon. The X-rays and other higher energy electromagnetic radiation created here bathe this volume of space in increasingly more energy. Soon the gravity of the more massive black hole will pluck the smaller one from spacetime and only the larger one will remain. Or two black holes of approximately equal mass are caught in a "waltz" orchestrated by their mutual gravity. They are gliding like two dancers an arm's length apart who are holding onto each other's hands. In a short while they will pull each other closer and embrace, becoming one. The universe holds wonders that could not have even been imagined just a single lifetime ago. What else hides from our view behind a curtain of gas and dust or concealed by a massive star field?

∙ 13y agoYes, black holes can "merge" and combine to become even larger black holes. This is doubtless the mechanism that creates supermassive black holes like the one in the center of the Milky Way, our home galaxy.

Do black holes live forever?
This answer depends on the size of the black hole. Black holes devour anything that falls onto the event horizon. As a black hole eats any and everything around it, it will grow. These black holes will exist as long as the universe exists. Small black holes do evaporate and disappear. This is because of something known as Hawking Radiation. Hawking Radiation is present in all Black Holes but its effects are inversely proportional to the mass of the black hole. This means that the larger the mass of the black hole the less the effect of the radiation is. A Black hole the mass of the Moon would evaporate almost instantly and the smaller the mass, the faster it will evaporate. You may think that a black hole that is larger but has nothing to consume will eventually evaporate, but you'd be wrong. Black Holes not only absorb stars and other objects, but it also feeds on the heat in space. Space is 2.7 kelvin, this is known as the Cosmic Microwave Background. A Black hole with a Solar mass of the sun will have a Hawking Temperature of about 100 Nanokelvins. This is far less then the 2.7 kelvins that space is. This is why large black holes will live as long as the universe itself, and small black holes such as those that could possibly be made with the Large Hadron Collider will never just stay open and consume the Earth. It is physically impossible due to the Hawking Radiation.Answer #2. #1 is correct however I would like to correct the everlasting black holes bit. No black holes will last as long as the universe. Supermassives have the advantage of accreting from the CMB right now. As the CMB cools they'll get less and less energy. Eventualy it's gonna hit an equilibrium where they're radiating as much mass as they're gaining through the CMB, then the scales will tip and all black holes will start slowly evaporating like their stellar-sized cousins did, ableit vastly slower, unless they continue accreting matter. Problem is, when that happens, the universe will be essentially dead, there will be no more stars to eat. Just vast nothingness full of supermassive black holes slowly dying and drifting masses of carbon (Black dwarf stellar remnants). So basically, no black holes live forever.
What is the name of particles that hit each other in a area?
Unfortunate.
One hypothesis to explain what asteroids really are?
Answer 1: Asteroids are formed by the collision of two planets breaking each into small pieces and floating off into space Answer 2: Asteroids are formed when planets are absorbed and crushed inside a black hole. The pieces of the planet are then ejected from the backend of the black holes into space as asteroids.
When two objects hit against each other they follow the law of action and?
the law of action and reaction!
What is the theory that reacting molecules must hit each other with sufficient energy in order to form products?
collision theory
When will a black hole hit your universe?
There are already black holes within the universe
How do crocodiles communicate with each other?
they hit each other
What happened when two black hole met?
both of the black hole will join together as one big black hole. they can either have a direct hit or both spin, twirling into each other until it create a new super big black hole.
IT IS WHEN YOu hit each other in a sport?
Contact
How do crocodiles communicate to each other?
they hit each others tail
Why has the moon got holes?
The moon has holes because it has been hit by asteroids
Meaning of hit it off?
Like each other
Obstacle to provide that black holes really exist?
The biggest obstacle for proof of existence of black holes has always been our inability to observe them directly, due to their nature of absorbing light and never emitting it (since the escape velocity of a black hole exceeds the speed of light). However, there is abundant evidence of their existence. For example, studies of the orbits of stars near the supermassive black hole at the Milky Way's core have shown that no object other than a black hole could explain their path - otherwise, the stars in orbit would hit the object (i.e., it is so small and so massive, that there is no other possible explanation).
What are crators on the moon?
holes that astroids hit
