Black holes

Assuming that black holes never "stop", what would happen in the future when a black hole becomes so large that it pulls in the entire universe?

Shit fucking blows up

SHIGITY SHIGITY SHIGITY

OH FUCK WE'RE ALL GONNA DIE

Division by zero becomes possible.

Dont worry! The new life will evolve in black holes since the material doesnt disappear anywhere... but you die!

eventually black holes get so huge that they collapse under themselves. by that time it may have already sucked in some planets though

wow, you are all wrong...

when a black hole sucks in everything, and there is nothing left besides black holes, they will suck in eachother until all matter in the universe is compressed to the size of a grain of sand, which case another big bang will occur, and the universe will expand once more, its called the big crunch theory...

>>8
Yeah, well, Big Crunch theory really isn't believed in anymore. Where are you from, the 1970s?

compressed to the size of a grain of sand, which case another big bang will occur
You have a common, but incorrect view of the big bang. The big bang did not start from a single point, but it was everywhere.

a singularity.

Jesus christ people do I have to correct you on everything ONE a black holes wouldnt suck anything from this planet why would it want anything to do with this planet and again ya we would get shrunk to a grain of sand NOONE ACTUALLY KNOWS ITS A MYSTERY OOOOOOOOO like ur penis (just talkin to that guy Anonymous) and if we were to get sucked into a black hole wow that sucks for us I mean really what the fuck are you gona do at that point run.... good luck well HAVE FUN BEIN DICKS!

The big crunch theory has nothing to do with black holes, and everything to do with the total mass of the universe causing enough gravity to slow and eventually stop and reverse the acceleration of the universe caused by the Big Bang, resulting in all the matter condensing back into a singularity not unlike the one that originated the Big Bang.

everybody is phail - it's obvious nobody took a course in GR

I don't know much about the eventual fate of the universe, since that requires detailed knowledge of cosmology, which I lack.  However, given the original question of the universe getting sucked into a single black hole, it would be a very simle answer.  The universe would be infinite and almost flat, and there would be a single black hole.  Furthermore, this universe would be exactly described by the Swarzchild (sp?) metric.  I assume lack of cosmological constant/Hawking radiation, which might screw things up.

It's essentially both.  When the big bang happened, there was a singularity, which means it happened at one point.  That point was also the entire universe, so it happened everywhere.

>>12
We have no experimental evidence of what would happen after getting sucked in, but current theory suggests destruction at (and possible incorporation into) the central singularity.  By definition of singularity, it is a point, which is infinitely smaller than a grain of sand.

Black holes do not grow in size. The accretion disk does.  Anything outside the boundries of the black holes gravitational field wont be effected.  Hence why we have not been pulled into the supermassive blackhole in the center of our galaxy (because 5 billion years is enough time to do that). Not to mention the popular theory is that like mini-black holes, black holes in general "evaporate".

Look it up.

>>15
Black holes can increase in size, along with its accretion disks.  As stuff falls in, its mass increases, which causes the event horizon to grow outwards.

The boundaries of a black hole's gravitational field is infinite.  I think you're saying that the deviations from Newtonian theory is very small far away, which is true.  It is also true that black holes are not magical vacuum cleaners that suck everything up.  The OP was assuming that somehow, everything already got sucked in.

evaporate -> hawking radiation; that takes billions of years

Brown holes can increase in size

also, hawking radiation likely has a negligable effect on huge black holes.

>>18
Which was why I ignored it in >>14

The word pirahna, is all I can think of that rhymes with marijuana

Marijuana MUST be legalized.
