What is the science behind black holes?
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) When the surface reaches the event horizon, time stands still, and the star can collapse no more – it is a frozen collapsing object.
How does string theory explain black holes?
In string theory, black holes are neither black nor holes. Instead, the best metaphor to explain what a fuzzball is to look at another compact-and-weird object in the universe: neutron stars. Neutron stars are what happens when an object doesn’t quite have enough gravity to compress into what we call a black hole.
Are black holes an illusion?
Theories about black holes have been in the news quite a bit recently, and new research is starting to point to evidence that black holes are not 3-dimensional, rather they are just optical illusions in the universe.
How many black holes are in the universe?
So in our region of the Universe, there are some 100 billion supermassive black holes. The nearest one resides in the center of our Milky Way galaxy, 28 thousand lightyears away. The most distant we know of lives in a quasar galaxy billions of lightyears away.
Does black hole really exist in the universe?
Yes. Black holes do exist in the Universe. Recently NASA scientists using their instruments have painted the pictures of these strange and fascinating objects in space. These black holes are formed because a big star collapses into itself creating a very high gravity due to massive mass squeezed into a tiny space.
What are black holes and how do they affect the universe?
Black holes are the strangest objects in the Universe. A black hole does not have a surface, like a planet or star. Instead, it is a region of space where matter has collapsed in on itself. This catastrophic collapse results in a huge amount of mass being concentrated in an incredibly small area.
What is the purpose of black holes in the universe?
The purpose of black holes is to enable the existence of large galaxies and us humans. Without them the universe would be a chaotic mess. Massive Black holes are at the center of galaxies and low mass ones orbit the massive ones at the center.
What if the universe became a black hole?
If you took the mass and energy of the entire Universe and turned it into a black hole, it would have almost the exact same density as the Universe itself, and an event horizon larger than the observable Universe. So does that mean that we are, in fact, living inside a black hole?
