OK, I'll slow down. Just for you. Apparently you need it.
I brought up hydrogen rising as a related issue, understanding that this experiment is different (and yes I actually did acknowledge this in a different post, and yes I understand the topic at hand). And yes no one has denied that hydrogen doesn't rise. But that's not what I am arguing, so that is pretty much irrelevant.
What several people HAVE denied is HOW it rises, which is most emphatically due to its average speed being above the escape velocity of earth. I realize this is isn't taught in school. I spent years reading science books, and only stumbled on it myself a few years ago. But I pointed out that a simple google search will uncover it in multiple scientific web sites and got modded flamebait, while the AC who posted that esacape velocity has nothing to do with hydrogen rising got modded +5 insightful. I'm sorry if this ludicrous reversal of common sense got me upset, but this still is a geek website, is it not?
Um, yeah, I basically said that in another post that this experiment is different. What I said was REGULAR hydrogen rises because of the escape velocity. Someone else denied this is the case and got modded +5 insightful. I pointed out that a simple google search will return multiple scientific sites showing this is the case, and I got modded flamebait. I don't feel bad about calling those people retards at all.
Hydrogen is both produced in our atmosphere and constantly bleeding away into space. It was also much more plentiful in the earth's past, and the vast majority of it has since escaped.
Even granting that hot air rises for other reasons, I don't think I'm missing the point. The subject is about hydrogen. Hydrogen rises because its particles' average speed is above the escape velocity of earth. This can be found on any number of scientific websites.
So why does hot air rise? Does heating air make it lighter? Hot air rises because the individual particles have more energy (heat), and so move faster. I will grant that this experiment removes some of the variables by forcing the anti-hydrogen to move at a particular velocity, but the vacuum has nothing to do with it. Hydrogen rises because of its velocity, which is mostly due to its light weight. Most, but not all, of hydrogen (think bell curve here, people) moves faster than the escape velocity of earth and so most of the hydrogen the earth started off with is gone. Some has remained, and some of what little we have left will also escape.
Googling hydrogen escape velocity got this on the first result:
"So the lighter molecules, such as hydrogen have enough velocity to escape from the earth, where as heavier ones such as nitrogen and oxygen don't. That's one of the reasons that you don't see much hydrogen or helium floating around in the air."
Except that regular hydrogen falls up. Since the average velocity of its molecules is above the escape velocity of Earth, hydrogen tends to move away from Earth. If anti-hydrogen has similar velocities, it should also rise.
Hey, I was just going for +1 Funny, not +5 Insightful. I'm a much bigger reader than gamer, but when I play I'm all for mindless violence. The attempts at plot and story are usually so contrived that I simply ignore them. Sometimes I just want to see how much gold I can carry, or if I can get all blue magic items, or to beat my last time finishing a level. They can keep their silly plot.
That's right, it's only a theory, like the theory of gravity and the atomic theory. It's hard to believe they would teach any of that in school. We all know the only explanation of the universe is Unintelligent Design, which says that the creator, blessed be his noodliness, was too stupid or drunk when creating everything. It's the only logical explanation for why Jar Jar Binks could exist.
As I remember, they didn't steal them; they superglued them to the ceiling. Not to mention rewiring all the phones in the White House. It took weeks and god only knows how much money to fix it all.
Thank you for correcting the only mistake in a/. summary. I'm sure your pointed observation will prompt the editors to take more caution when writing, and there'll be no more mistakes.

I have. I read it in these things called books.

This got modded informative? Are you all retards? See my comment further downthread, or just google hydrogen escape velocity for yourselves.

Yeah, I don't know why they didn't consult with me first. I could have saved them a lot of time.

And I can't tell you how excited I was when the FBI called and said they wanted to interview me right away.
Yeah, it would have been so cool to log into DARPAnet while on the go.
If I wanted artful stories, I'd read a book. All I want to do is chainsaw zombies, preferably on a Wii.
Yeah, that's how I got into intelligence analysis. I just started handling classified documents, and pretty soon I got some recognition.
I thought Ron Howard already did that movie.
How does a 5-digit /. user ID talking about desired computer specs qualify as troll? What the hell is going on around here lately?
And Intel's ad campaign should have Radiation Man saying, "Up and Atom!"
Fallout Boy could sing the ad jingle.

Wouldn't the same technique work for VOIP as well? And since when is referring to previous relevant /. articles being a troll?
Didn't /. just post an article a few months ago about how the NSA figured out a way to block steganographic messages in VOIP?
10,000 metric tonnes? What?
If it were filled with water, it would about 6,500 lbs. I think your math is a *little* off.
I heard that they made Goobuntu, a modified Ubuntu, but later learned that was an urban legend. Is there another distro they've made?
