The size of a black hole is a meaningless quantity. The black hole itself, meaning the matter contained within, is infinitely small. However black holes can be defined by their schwartzchild radius which is the size of the event horizon. Look the equation for it up somewhere.
It may sound crazy, but yea. there is this big as black hole in the middle of our galaxy, so we orbit the black hole.
its about a guy who falls in love with a girl but isn't expecting it because he never thought he'd fall for anyone, but now that he's in love it sort of feels like he's in a never-ending fall...never-ending a.k.a black hole...and the love he has is really strong or big and or super-massive...therefore he's falling in to a super-massive black hole
scientists think that the Big Bang which generated the univerese waas the consequence of the explosion of a massive black hole. so the big bang
While scientists have never actually SEEN a black hole (they are called "black holes" because their gravity is so great that not even light can escape!) we believe that super-massive black holes are at the hearts of most galaxies. These super-massive black holes might be the mass of a million stars the size of the Sun, or larger.
how many stars there are in the galaxy its size in light years its mass in terms of our sun[ like 100.000.000.000 solar masses]how big is its super massive black hole in the center and its mass
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.
stellar black holes, no none at allhawking black holes, no none at allsuper massive black holes at galactic centers, no none at alluniversal black holes, yes we are an example, if the entire universe is indeed inside an ultra massive black hole as would be suggested by the combination of big bang theory and black hole theory
Massive, big, and very luminous stars turn into black holes most of the time
Unlikely. The universe is a very big place, even next to the largest black holes we know. For a black hole to suck in the entire Universe, it would need to be nearly as massive as the universe itself. There is no way that such a black hole could form.
Neptune does not have a black hole
Stars like the Sun are not massive enough to become a black hole. Instead, in several billion years, the Sun will form a white dwarf. Black holes can be formed if the remaining core of a star after it had gone supernova is very massive (more than 2.5 times the mass of the Sun).
No. No black hole is big enough to do that.
