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.
What else can I help you with?
Does really milkyway galaxy revolves around super massive blackhole?
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.
What is the song Super-massive Black Hole about?
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
First 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
Is there such thing as big black holes?
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.
What are features to include about how big is a galaxy?
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
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.
Is there any chance of life in a 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
Which type of star often turns into a black hole when they die?
Massive, big, and very luminous stars turn into black holes most of the time
What do you call a dead star caves in itself due to its very big mass?
When a dead star collapses in on itself due to its massive weight, it forms a black hole. A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.
Can a black hole destory the galaxy?
No. No black hole is big enough to do that.
Is our sun big enough to form 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).
What star can make a black hole big?
Since the radius of a black hole is directly proportional to the mass it contains, one can safely say a massive star can make a black hole big; the more massive the star, the larger the black hole. Note that, depending on composition and some other factors, a heavy star may or may not blow out much of its mass in a spectacular explosion (supernova) and the small remnant it leaves behind may or may not be a black hole - it could potentially become a pulsar or neutron star instead. Black holes may also be companions to massive stars, and their size governed by how much mass they accumulate - since the star may supply the black hole with a fairly continuous stream of matter captured by gravitational effects from the companion star and thus the black hole continues to grow in size.
