The black hole pulls all of your atoms in ONE direction, you are pulling both strings in the opposite direction.Quote:

Isn't hawking radiaton just a hypothesis? It has never actually been seen or measured. Am I right?Quote:

If there were even a grain of chance that a black hole could be created and sustained well enough to swallow us all whole, don't you think there are grounds for concern? I understand there are well-qualified scientists armed with assurances that nothing bad will happen, but our knowledge of matter is far from trustworthy, else this LHC would not have been built. This is especially true if these well qualified-scientists don't actually have any substantial evidence for Hawking Radiation. Aren't the same people in this thread, who demand concrete proof for everything, the same people saying that everything will be fine because a bunch of scientists have a solid theory on what will happen?
Just one more thing i'd like to bring up, just to be pedantic (and i don't know if it has been pointed out yet):
Honestly, if you were given even a shade of a reason to doubt the safety of apples for humankind, would you eat one? Honestly? If you calculated your risk wrong you would effectively be destroying mankind. There is, after all, reason to peoples' objection to this particle accelerator, so there would likewise be reason to doubt the safety of apples. They sure are delicious and healthy though, aren't they?Quote:
The basic formula is "it's very unlikely BUT it would kill EVERYTHING so that multiplies up the risk", which might sound reasonable, but by the same argument I could say "Nobody eat apples in case one contains a rare virus that could RENDER EVERYONE IN THE WORLD STERILE".
But, as i say, i'm simply playing Devil's advocate with these questions, which people more knowledgeable than i are welcome to answer. I for one don't really care about whether they flick the switch or not. If they do we will probably have some new and interesting information about our world. If they don't, those discoveries will wait. Life goes on. I don't think the world will end, but then as i pointed out in the first place: i'm ignorant on the matter. I do however see that any doubt from anybody who knows anything about physics is valid. This Wagner fellow may not be Stephen Hawking, but still seems to know one or two things about physics. No great physicist has been without their errors, i'm sure.
You know, i've always wanted to know what it was like to be sucked into a black hole. Maybe i'm in favour of this LHC after all! :D
(i voted undecided, because i'm not worried either way at this stage)
Well it's kind of ironic that everybody's saying 'silly science, what about black holes??' considering if it weren't for science we wouldn't even have any concept of a black hole in the first place.
But yes there is a certain moral ambiguity I'd say.
When they first tested the a bomb there was a small chance that it could have ignited Earth's atmosphere.
God damnit!!!

Yes, because the people in charge of the largest particle accelerator in the world are going to be laymen administrators that demand MORE POWAH! while bashing their fists on the control panel.
Phew...God saved us, again.
Don't take my dreams away with sarcasm...Quote:

Ah yeah it does LF =/. Buuut, I guess caution beats clumsiness :P
In my opinion, the LHC is a joke.
Because the advancement of physics is so funny, right?Quote:

Why is the advancement of physics a joke? I think it's amazing to discover how it all began, and to explore "reality" we live in even more.Quote:

Don't immediately assume that critisism on the LHC project means I hate physics. Don't make a religion out of it.
To Dajo: good job immediately assuming I'm a religious nut or anti-science conservative/fearmonger. That's not very scientific now, is it?
Don't immediatly assume the LHC is a failure then.
What I said is fact. The LHC has never functioned on full power, and somehow it keeps breaking down before they can even start using it.
actually, it wasn't really directed towards you, I just wanted to post that hilarious comicstrip.
It's only been operational for a year and a half, you haven't even given it a chance. You'll fail a lot in life if you are that quick to admit defeat.Quote:
