brace urself...tis gonna be long...
i tot that the galaxy rotates around the black hole just like the way the solar system rotates around the black hole.
there isnt any good involved really....maybe it simply eats our thrash and recycle it in its singularity.
if the black hole isnt here...then perhaps our galaxy would have so much thrash that in years(millions/billions/more)...our galaxy would look like ur thrash can...cept that they are in atoms form.
perhaps what black holes do is that they fix our positions in space by using their gravity like how the sun does.
the fate of our solar system is simple, the sun would explode in a supernova(am i using supernova correct here?)...and the solar system would turn into stardust while the sun becomes a "white dwarf".
what i think would be the black hole would suck the whole bloody galaxy into itself then explode "someday", if they ever do. but the numbers state that our universe is constantly expanding, which might mean this will never happen.
to be exact, we cant be sure what use/effect black holes have on our galaxy/universe. we would take millions of years to find out!! to find out whether black holes affect us, we have to find out how it works. we cant simulate such immense content of gravity, we can only assume and speculate using laws and theories...particularly by linkin existing laws and theories to form a new equation and hopefully we will find out the ultimate of the blackhole...DA SINGULARITY.
most of the speculations here are what happens on the way down...we cant speculate what goes on down there.
ok mike is passed to the next good man.
reason why this forum is so seldomly visited is cos everytime u post somethin...its gonna be long, and we have to rack and crack my brains to answer. so sorry for the wait.
guess what...i got my physics test tomorrow! and *ahem*...i made too many careless mistakes in my math paper...argh. dont think im worthy of posting here...ehehhe....
