Do Black Holes get bigger when they suck in objects?

Question

Does the mass of the singularity increase?

Answer 1

not bigger so much..as it accumulates more and more mass until it basically collapses on itself..which creates a singularity and then another big bang!

Answer 2

I saw this on a show called Hyperspace with Sam Niell, the guy from Jurassic Park.  When material enters a black hole, it then belches it out in a stream of matter traveling at light speed.

Answer 3

no the black hole dont get larger because if you go in one you or an object will become a string and when they reach the bottom you become a microscopic dot that is what is going to happen to the sun!

Answer 4

Yes, the mass of the black whole is equal to the mass of the star that collapsed to form it plus all of the matter that has fallen into it.  That's why you may hear them talking about "supermassive black holes", those which have a mass of billions of times our sun's mass.  It is unknown exactly how a black hole's volume increases as matter falls into it, but it's generally thought that once the core collapses into a singularity, all matter that is subsequently added becomes part of that singularity (which has zero volume).  However, the definition of a black hole can include everything within the Swarzchild radius, which is the same as the event horizon.  As more matter falls in and the total gravity increases, the event horizon will grow, however the bulk of the matter goes straight to the singularity.

Answer 5

Yes, the mass of the black hole increases, and therefore so does its radius.

Answer 6

yes both the mass and the according schwarzschild radius for that black hole increase but the addition rate should of course be larger than the evaporation rate

Answer 7

That is correct. The more matter and energy a black hole swallows, the more massive the singularity, and the bigger the event horizon surrounding it becomes. The size of the event horizon is directly proportional to the black hole's mass. Double the mass of a black hole and the radius of the event horizon also doubles.

Answer 8

Well by my best reasoning, my girl friend says I am a black hole at the dinner table, and gradually I am getting larger.  So I conclude that black holes DO get bigger but...

You know.. Im not sure where Im going with that last bit, but I think if I continue I might get banned from Yahoo Answers ;)

Answer 9

who knows?

Answer 10

Yes but it is very small in comparison to the sun it just ate...
