How big are blackholes?
They can be only a few miles across, while others are several million miles across.
A black hole can have a mass of about 50 billion suns, which is the limit.
Black holes can grow larger, depending what it sucks.
Since black holes are suns that have exploded, explosions spread, causing the black hole to emerge.
When our sun goes to the next stage in life, the black hole, it might not make a black hole, or a very small one.
There are two ways blackholes form: Massive blackholes - these are formed by collapse of stars having more than 3 times the mass of our sun, when the stars die. Micro blackholes - these could have only formed in the big bang. Their event horizons are roughly the size of a proton and their mass is similar to that of a mountain. Unlike massive blackholes, which last forever, these evaporate then explode giving them a…
15billion years ago the birth of our Cosmos or Universe was born. My theory is that this was due to an incredible compression perhaphs that which takes place in the density of a blackhole. Since blackholes are at the center of every galaxy ther can be many big bangs taking place even as this is being typed.
Blackhole are way more dangerous. Since there is only one star in our solar system and our planet will be long gone before our star even going to explode, but Black holes are worse because there are 'wondering black holes'. So there are blackholes out there in traveling the universe and eat everything up along its way so you know, there can be wondering blackholes coming to our solar system.
Blackholes are not really holes, it is where a huge amount of matter has come together and has been concentrated into a very small area. Mass is related to gravity, any mass has gravity, but you don't really notice it until you have enough mass like that of the earth. There is so much mass at the centre of a black hole that even light cannot escape it's immense gravity - that's why it's black.
"The" black hole is wrong: there are many black holes, not just one. If you mean a specific black hole, please clarify which one.A black hole can destroy anything that gets close enough. The closest known black hole is at a distance of several thousand light-years; at that distance, it is harmless. It is unlikely that Earth will collide with a black hole as long as Earth exists (say, for the next few billion years)…
