All I wanna know about hese black holes is:

Do they really contain all the items that come up missing, like some folks say? My wife always claims that's where the other sock that's missing from a pair goes.

Nevermind yer funny little chickenface there; Daryl Beano Ratting Oort of yer Grey Alien friends, yuh heeeah? I mean, just because yer the House FizzyCyst dozen give yez License to Chill, yer know? Cold Dark Era, indeed.../ But now lookit, didn't Hawking Hisself declare (thru his voicesynthesizer) that stuff CAN leak out of the black holes, after all? Next thang y'know, they'll have Hair, too.../ But these mere Stellar black holes are just little random Pipsqueaks, ain't they? The galactic cores, that's the real thing. Oy.

Well, danged, Micheal. It's not like there a lot of light out there in space, so me and the Wes Ginny slide rule figure that the "ripple" will get be slowed considerably by the *speed of darkness*...

What intrigues me is this:

-- Those black holes are 400 million lightyears away.
-- They appear to be 100 million years from collision.
-- That means the collision already happened... 300 million years ago.

Se we're not going to see anything happen. But what about that "gravitational ripple" effect?
Would that spread at the speed of light? Faster? Slower?

Dammit, Don, I was going to add that story.

Makes ya feel kinda small, donit?

In Astronomy 101, the prof says, "The sun will have used up all its fuel about five to seven billion years from now, and when that happens, it will swell into a red giant, expanding well beyond the orbit of earth before it finally collapses into a white dwarf."
A hand goes up in the back row.
"Yes?" says the prof. "You have a question.?"
"Yes. How long did you say it would be before that happens?"
"Five to seven billion years."
"Oh, thank God! I thought you said million!!"

Mooman --

Actually, that might be the key to the pesky question of what could possibly cause a big bang!! Universes in collision, one of matter, one of antimatter. Kaboom!! So we only see the amount that got leaked in to our share of the aftermath.

THe rest is all in the next universe over, the one Lewis Carroll and Gary Larsen and a few Mudcat denizens are secretly from... :>)

Amos,

Shouldn't there theoretically be as much antimatter as matter? Perhaps we just haven't found it so far?

Thanks for the link Michael!

well - the thang about a black hole is that the gravity is so intense that not even photons escape - so wouldn't expect much except the "ripples in the gravity field" to be observable.

First of all Amos, Iz gon on record of sayin' that I did *not* have sex with that "perturbation".

With that said, nice guess but like guesses tend to be (the bobert yawns) just.... a guess.

It is not a matter of anti-matter. It is a matter of matter, but made so dense that its gravitational pull is phenomenal. Two of them colliding will cause perturbations all across the frequency spectrum, but it is debatable how much of what would actually escape. Ripples in the fabric? Well at least, ripples in the gravity field.

Anti-matter is something else again, rarer by far than black holes. Or so it seems.

Danged, and to think I've been worried about George Bush?

Silly me...

Ahhhh, any math wizzards out there? Okay a black hole is like negative numbers, right? So if two of 'em hook up do they create matter? Or twice as much anti-matter?

PM me for the correct answer...

It will probably be a great deal as if we/our universe/multiple worlds were all shoved into a front-loading clothes dryer and set going. It will take sorting out when it stops.

"That collision would not be viewed on Earth for at least another 100 million years, the astronomers said."
