Yes a full sized blackhole would take a very long time to radiate away, but you could have had smaller black holes formed in the early universe.
As near as I can recall, from what Donald Coyne was explaining, black holes have a life span (albeit a very long one) which go something like this:
A large mass forms, could be from a sun or suns.
It continues to attact matter until it reaches a certain critical size (like 1500 lyr diameter!)
Due to the extreme amount of matter accumulated it begins to collapse, reaching an incredible density and kicking out staggering amounts of energy from its poles.
Effectively this process converts the matter of the black hole to energy.
At some point the black hole, as it approaches maximum density also approaches minimum mass and ceases to exist.
Sounds like an interesting read...if I want to continue lying in bed at night staring at the ceiling, with my mind completely blown.
Recently I joined the local astronomy club in Santa Cruz, CA. The night I joined the feature was a lecture, "The Mystery of the Ultimate Fate of Small Black Holes" presented by Donald Coyne.
The scope of matter, energy and time necessary for various things to take place is baffling, at least to me. Black Holes take a lot of time to be created. The Universe is estimated to be 13 billion years old. The theories put forth were such that black holes have formed and are dissipating (something about reaching a critical mass then collapsing in upon
themselves, and kicking out staggering amounts of energy in radiation.) It seemed to me that for some of these things to have taken place the Universe would have to be older (as some of the processes would take longer than the universe has been in existence for.)
It's fascinating stuff, but a little goes a long way.
Oo! My widdo bwain, it bwoo my widdo bwain! Oo! Oo!
Whoah; that sounds like a very interesting (though morbid) story. I don't suppose you have any more details that I could google on?

I would think that that would'nt be a very efficient way of transporting/making alum. parts.
WTF does there need to be 1300F molten metal on the interstate for?
As it was explained to me, it's very efficient. Aluminum hauled in tankers moved between locations in only a few hours, thus saving having to build a facility for melting the aluminum. I knew there was an aluminum smelter near Toledo, OH, which frequently trucked molten aluminum up to Saginaw, MI.
As much as it shocked me when I first learned they did this, it should be no less shocking than all those gasoline/petrol tankers you see on roads everywhere, which would turn you and your car into crispy critters just as efficiently.

I like the iron idea. I think I'll hop over to the local hardware store and grab some on the way home.
Depending upon where you live, you may be suprised to find trucks on the interstate hauling molten aluminum. There has been one accident to my knowledge, vaporizing the occupant of a car.
What's the world coming to? Why can't we simply limit ourselves to portable music? Must we *always* have 2.9 billion forms of electronic media at our fingertips in the ever rare chance that our natural surroundings ever become boring?

Spammers don't need programs like that. People who have ads on their web pages and want to generate hits on the ads would want that.
Spammers, on the other hand, have now moved onto blogs lately. Fred Rodriguez, a rider Emeryville, CA, for italian team Aqua e Sapone has spams for the usual penis enlargment, diet pills, cheap computer eqz, etc. on his guest book. Spammers got no shame, just like this fool.

Anyone so daft as to outsource content to India (or any other country) and market to the US is probably on their last legs anyway. No offence, and I'm sure Indians can write good technical documentation, but if you don't have the native insight or point of view, you're just writing stuff that will baffle the reader as much as that useless technical mumbo-jumbo on MSDN (1. Search for help on Google, 2. Ignore MSDN links as they're useless 98% of the time.)
I don't got to italian pages, german pages or spanish pages because unless the have some idea who I'm writing for I'm not likely to find help there. They're trying to write for their own targets. I won't bother with Builder.com for the same reason, as they evidently only mean for indian readers. What a disappointment it will be when they realise they can't make the same revenues because outsourced employees don't have the same spending power.
Like the blinding flash, shockwave and mushroom cloud wouldn't give you a clue
Like you haven't been paying any attention to this Dirty Bomb stuff.
Let me give you an example: What looks like a car bomb goes off on Wall Street. It turns out Al Qeada operatives have scraped together (from 10,000 smoke detectors or wherever) a bunch of radioactive material and included it in with their Tim McVeigh-style fertilizer and fuel oil bomb. Physical damage may be minor, but hundreds of people get exposed to the nuclear toxins and the grounds will take a major effort to clear.
Granted, one move like that and treaties with Pakistan or not, the US will be hell bent to exterminate Al Qeada.
Pififully, this is the one piece oof hardware around the house I can't get rid of. *SIGH*
Years of video tapes in several fanfold paper boxes (the big 132 column stuff) take up a lot of space and I really need to get cracking editing this stuff and burning what I want to save onto DVDs. I've even got the entire run of Max Headroom, the first time it aired.
The last time I took my VCR in for a fixup it took $125 out my pocket and I thought I should have just bought a new one for $60, but I'm hearing the new VCRs last about 1 year, this was top of the line (NEC 960v, iirc) bought back in 1986.
So, when did it become fashionable to predict the deaths of everything from consumer eletronics to companies?
It's been fashionale to:
Predict the future
Rattle on about spifty new things that'll be out RSN
Contemplate the next acquisistion of Microsoft
Contemplate the next anti-trust action against Microsoft
Poke fun at Duke Nukem 4ever (RSN)
Write in glowing terms about the next generation of electronics (MP3 players, cell phones, PDA's, Ditigal Cameras, combos of all four)
How could it be out of character to lay some of these things to rest, when their time comes?
Personally, I've got a video card which allows me to record to HD whatever, whenever I want without any fees. When I can do that, why should I buy a Tivo, or even Replay? And wasn't someone b!tching a while back about Tivo or someone collecting viewer habits?
AOL builds horrible, buggy software. So does Microsoft. They are a perfect fit!
If it happens and television, internet, operating system, instant messenger, office, email, music, etc. are all integrated, well, there's one thing for it:

According to the report, Time Warner lawyers have also been analyzing possible antitrust issues from such a deal
Besides having to sell over Netscape (I think I have $10 here...) wouldn't there be a problem with Microsoft's existing deals with Comcast?
The Post quoted Time Warner spokesman Ed Adler as saying "such speculation is silly and pointless." Microsoft declined to comment on the matter, the report said.
Well, when they deny like that, what additional proof does anyone need that this is pretty much a done deal?
Daffy Duck told me Marvin the Martian was there and was going to destroy the earth! Don't tell me television has been lying to me all these years.
As an authority on this subject (I can do the Marvin voice as well as Mel Blanc) I'd like to point out that Bugs Bunny (whose voice I can't do) was the first to encounter Marvin, as Marvin planned to destroy the earth with his Illudium 236 Explosive Space Modulator. When did Daffy Duck encounter Marvin?
The delay is only enough for Worf to open his mouth and talk. It is not long enough to replay "Data to Lt Worf." I freely admit I'm crazy.
The real fantasy here is that Worf, or anyone in your workplace, will answer a communicator that fast. Has there *ever* been a busy signal?
"Lt. Worf is on a nother line, please hold...dah-dah-dahhhh..dah-daddah-dah-dahhh..."
Now when you face someone who appears to be talking to you, you won't see a headset and think they may be on a call. This should add to confusion. (Like that funny phone commercial where the woman comes onto tha man, she's unaware is on a call.)
At the rate Rowling is churning out the books they'll have caught up with her. Then what? Harry Potter 5.5 the Gap Filler?
I wouldn't be inspired to read the books after seeing the films, but I read about 30 books a year and see maybe a third that many movies. (next on my calendar is Kill Bill vol 2) Harry Potter is a pretty good yarn, a bit smarmy in parts, but good nonetheless. It was a major seller around the world before the first film debuted. Also, Harry Potter 5th book made more money in sales the same weekend The Hulk appeared in theaters. When was the last time a book outstripped a big film release?
although that one somewhat missed the point by showing the military, eventually, triumphant.
No, that wasn't the military, that was Will Smith as a Buck Rogers type character saving the earth with his own macho and bravado.

Nice CGI, incredibly boring story. I can't really watch it again because it's just not interesting. Shallow action pics are like a one trick pony. Once you've seen the trick you could care less about seeing it again.
Bladerunner, as someone else alluded to (as a possible remake target) is still something I'll watch every year or so, because it's a great story.
If you look at the bright side, if someone enjoys the movie, they'll be more encouraged to read the book. I read Heinlein's Starship Troopers after I saw the movie and thought "Wow, they hacked the crap outta something that really doesn't translate well to the movie media at all." (And I also am reading the Bourne Identity cause I enjoyed the movie a ton. And the book is VERY different than the movie, and much better, might I add).
Better idea: Skip the movie and simply read the books. When I've read books and seen movies I'm often disappointed, because someone went along with the philosophy "this book won't translate into a movie", usually wrongly. I think lots of books would make great movies, but Hollywood has a few things in mind, like Marketing and Merchandising. They don't believe a good story can be sold, but an bunch of vapid acting, CGI and action can make up for depth.
Probably one of the most memorable movies of all time, Star Wars: A New Hope challenged that attitude, but Hollywood is a creature of habit and goes back to what it considers "Tried and True"
