Astronomers have weighed the biggest known black hole in the Universe.
The monster celestial object is 18 billion times more massive than our own Sun, says a team from Finland - six times larger than the previous record.

Yeesh...where do you pick up a scale that can weigh that much? Hee hee hee

That's monstrous!

I think its amazing whats out in space.

You look at earth and how big it is, and its nothing compared to Space. To think that the universe could be millions times larger than what we already know. Its just so amazing. And black holes, what if they are some sort of portal to another dimension ? Or there is another universe other than ours, or life on other planets and other planets we have not yet discovered. Imagine getting lost in space!

how can you weigh a hole?nothingto worry about straight is our quest.like pool the cue knocks the baals around.

A black hole is not actually a "hole" but was once a star that has collapsed in itself because it has exhausted its fuel supply, no longer being able to sustain its size. It's size is proportional to the amount of radiating energy that the nuclear reactions within it produce in relation to its overall mass, which is the source of its gravity. Since the mass (gravity)does not diminish as its energy does, its own gravity compresses it continually inward until it reaches a point called singularity- or infinate density. At this point gravity is so pronounced (strong) that not even light escapes its pull, hence the name black hole. It creates a region in space where all matter within the range of its gravitational field(event horizon) and light are pulled into it and compressed into singularity.

Under these conditions, it would never be possible for a human to survive being sucked into a black hole, as the closer one gets, the greater the gravitational pull. The theory of what would happen, is called spaghettification.The gravty increase in strength the closer you get to the center or singularity, and therefore acts proportionately on whatever foreign matter is being sucked into it. Say your floating torwards the event horizon feet first. Once you enter the event horizon, the gravity increases bit by bit in relation to the closest matter to the black hole. In effect, since the closest matter would be the molecules or atoms in your feet, they would be sucked in with increasingly greater force and speed than the matter furthest away-the top of your head. You would be stretched and stretched and stretched as you went deeper into the ever increasing gravitational vacuum. In essence, you would be turned into spaghetti.
Black holes are always increasing in mass, as they suck in the matter Aound them(other stars, astroids, planets,whatever) and therefore always increasing in weight and strength. They are in effect, galactic parasites, with a 100% mortality rate of their victims. If a person wants to become one with the universe, black holes are the ticket.

So a black hole is a bit like a whirl pool then ?

A black hole is pure nothing. Gravity that teeters on the edge of infinity, gravity strong enough to prick a tiny hole in the fabric of space-time.

What I don't get is the event horizon...they say it's a point where nothing can move either forward or back. It's the spot where a permanent image is stamped into the very threads of space, forever.

But they say, too, that a black hole can't be seen with the naked eye. There's black holes out there that are immense! They've swallowed up stars much bigger than our own.

So...wouldn't these stars have been stamped into the event horizon? Wouldn't the black hole have so many images stamped into its event horizon that it would be much like a dazzling star in space?

Also, they say nothing (and then they add in "not even light" even though light is something) can escape the pull of gravity from a black hole.

Then they say they know there are black holes out there, because a black hole throws off jets of radioactive gases millions of miles into space from its poles.

Ummm...wouldn't those jets be "something"?

Am I being difficult again?

Here's a site that gives a summary of the most popular black hole theories.Its from 1993 so it may be a bit outdated, but it was the easiest I found, so far to, comprehend
http://www.astronomical.org/astbook/blkhole.html
I was wrong on a couple of things, so sorry about that. But hopefully this site will be interesting to yas.

Carolina...don't be sorry.

Nobody but God can be completely sure, ya know

After all...all we have so far are theories. You have just as much right to have a theory as the rest of anybody.

Thanks Whirlwind, but I was wasn't presenting my theory, I was trying to present what I understood someone else's theory, or the main consensus, to be. I just felt I needed to apologize for giving out wrong info. Don't want to be someone who quotes falsehoods as facts, ya know? Thanks for the encouragement though, bro!
