How Do Black Holes Form in Galaxies?

KOMPAS.com– Black hole or blackhole is part of the space in a time galaxy, which has the strongest gravity, not even light can blur.

However, what it is actually black hole and where it comes from, as well how black holes are formed in the galaxy?

Astrophysicist Neta Bahcall, from Princeton University in New Jersey, United States of America say that black hole is an object or point in space, where the gravitational pull is so strong that nothing can escape from it.

These objects can even suck up light waves and this is the reason why black holes are black.

According to Swinburne University of Technology at the Australian Center for Astrophysics and Supercomputing, black holes are formed because of star a very large one falls on itself or collapses.

When stars in a galaxy run out of fuel for fusion, or are nearing death, the level of outgoing radiation is weaker than the inward force of gravity.

When this happens, at the end of its life, the star will explode and the explosion of the star is called supernova. Supernova is an exploding star that blew some of the stars into space.

According to NASA, Albert Einstein’s general theory of relativity predicts that it takes a large mass to create a black hole in space time.

If gas and dust surround the object, the material will be sucked into the belly of the black hole, creating a bright burst of light as the gas and dust heats up and then infuses this mass into itself.

Reported Live Science, Wednesday (28/8/2018) when two black holes meet, the gravity or strong magnetic field generated by each black hole will attract each other and make them closer and then rotate to each other.

Their collective mass will shake nearby spacetime structures and will send out gravitational waves.

Researchers believe that supermassive black holes used to be much smaller, forming more modest-sized black holes in the early days of our universe.

But over time, these objects or black holes absorb gas and dust, merge with one another, so that they continue to grow until they become very big and strong.
