Exactly, so you can't reassure us nothing will go wrong.
But the likelyhood of something going wrong is very unlikely.
For a start, protons crash headlong into other protons all the time.
We're still here, aren't we?
So, that disproves the whole "Protons smashing into protons will end the world!!!!!" thing, doesn't it?
Secondly, if blackholes were to be created, they'd be miniscule and evaporate before they even had a chance to turn into something.
You only find really powerful Blackholes in space because they're created by dying stars, plus, there's no gravity out there.
Thirdly, even if these "So-called" black holes were to end the world, who's to say that we'll die? Do you know what goes on inside of a black hole? It could take us to a Parallel Universe, it could take us back to the past when we started to kill the Earth.
It could be Natures way of giving us a second chance to not kill her hard work.
You know the saying.
Hell Hath No Fury Like A Woman Scorned.
You only think a Blackhole will kill us because Hollywood glamourised the truth. Not even they know what goes on inside a black hole. They just glamourised what they thought was the truth to turn it into a Horror Movie.
Lastly, this could be our only chance to find out what happened at the beginning of the Universe. If the Higgs Boson doesn't exsist, then hundres of years of work could go down the drain and we'd have to re-learn everything about how life was created here on Earth, how the Earth came into being. Because at this minute, no-one is completely sure about how the Earth was created. How is it so round? Why does it have a different Atmosphere to other Planets?
How does the gravitational pull of the Sun keep us from endlessly falling into nothingness?

Well... A black hole would almost certainly kill us because its gravity would be SO strong that the tidal forces would rip our bodies (and everything else) in to its elementary particles before we got too close. But true, we don't actually know what's inside it - that's something we'll probably never know, unfortunately, due to its very nature. I mean, we couldn't well send a probe in to have a look if it's going to get atomised!

And we do know many of those. It was (and these are the best available scientific theories, which I should also point out are different to the word 'theory' in that the latter is basically a guess and the former has facts to back it up) thought that Earth was formed from the accretion disc around the sun as it was forming, with matter congealing and gathering together under the influence of gravity. It's round because of gravity as well - everything is being pulled towards the centre, so anything too tall or too out of shape will get crushed down by its own weight.

The atmosphere... Well, that's something we're still working on, but we're looking at Venus and Mars (extremely similar terrestrial planets which have an atmosphere, even if it's pretty tenuous on Mars, but there's plenty of evidence that it used to be thicker) to get answers for that.

And we know how Earth stays in its orbit, thanks to Kepler's laws of planetary motion and ESPECIALLY Newton's law of universal gravitation (although you use Einstein's laws of general relativity for more specific examples), but how gravity itself works is still a bit of a mystery - it's thought to be its own particle, the graviton, but we still need to learn more about its nature, and why it's so weak compared to the other three fundamental forces, and if it, y'know, exists. That's actually one of the things that the LHC is investigating, bringing us back on topic!

Aaaand I'm going to be quiet because I'm REALLY living up to my Mr Science reputation ^_^

I'm quite excited about this. If they can discover more Fusion and matter iteself, it can change the world. People are freaking out over nothing.
It's so unlikely to destroy the world that it's nearly impossible.
It's a GOOD THING.
$6 Billion is NO COST when you thuink about the good it can bring to the world... The power it can supply to so many people is ASTONDING, and it's more likely to help the world than hurt it.

Go scientists.

According to an old Cosmic Variance post, the power of one of the LHC's proton beams at full energy is 10 trillion watts (TW). (A watt is a joule of energy per second.) A household microwave produces 500 to 1000 watts of power. Let's call it 700 watts. And defrosting a frozen pizza takes about six minutes*. So that's

700 joules/sec x 360 sec = 252,000 joules of energy needed to defrost a pizza

Therefore:

252,000 joules / 10^13 joules per second = 3x10^-8 second for the LHC to defrost a pizza
That's 30 nanoseconds (billionths of a second).
Quote taken from: How long would it take the LHC to defrost a pizza?: Scientific American Blog

Now THAT is advancement I care about, and impacts my daily life

Ryttu3k- I think I lurve you. XD Don't shy away, you're the voice of reason in this thread. I feel bad that I discovered this thread too late to fend off the dramatics whailing this is going to start a black hole...

And to whomever corrected pippy on the whole dark matter thing, thanks. ;D I'm doing my science research project for school on it. Basically it's this class where you choose a topic sophomore year and then reasearch it and such and display your findings at the end of senior year.

I'd take the time to post what I've learned so far but there's too much. D; I advise you, pippy, to go onto the NASA site to get a brief lesson on it.

Well, I already know how our Atmosphere was formed.
Gases and whatnot pumped out by the very first volcanoes.
But, what I want to know is how that makes our Atmosphere lighter than Jupiters Atmosphere (Which, if we were to go there, would crush us)?

Well, that's down to pressure. It's not so much that Jupiter has a heavier atmosphere - in fact, it's mostly hydrogen with a smidgeon of helium, which are the two lightest elements. In contrast, our atmosphere is nitrogen and oxygen (again, with a few other things, like argon, carbon dioxide, water vapour, a tiny bit of methane, stuff like that), which are heavier.

Jupiter's atmosphere would crush us at certain altitudes because there's so MUCH of it. Almost the entire planet is, well, atmosphere, with liquid hydrogen inside and POSSIBLY a rocky core buried waaay down deep. Again, it's down to planetary formation and a large amount of chance - it so happened that there was more gas in the outer parts of our solar system when it was forming, which got picked up by the planets that were being made there and scrunched in to a ball.

The fact that, in this solar system, all of the gaseous planets are on the outside (Jupiter and Saturn are Jovian planets, ie. Mostly hydrogen, and Uranus and Neptune are ice giants, largely hydrogen and helium but also with a lot of ices - water ice, frozen ammonia, frozen methane, stuff like that) and all of the terrestrial (rocky) planets are on the inside is pretty much down to chance. We know of many, MANY other star systems, now, and these systems vary hugely.

There is, for instance, Gliese 581, which has three known planets - all rocky, terrestrial ones. As far as we know, there are just no gas planets there. But something like 55 Cancri has five known planets, the innermost of which is probably a terrestrial 'super-Earth' (with a mass similar to that of Neptune), while the other four are all Jovian gas giants. In the case of 55 Cancri, the four innermost planets are all clustered around in an orbit smaller than that of our own Venus, while the fifth has a similar orbit to Jupiter's. That's a hell of a gap between them!

But yeah - our atmosphere is thinner than Jupiter's pretty much by chance. If there had been large quantities of hydrogen gas around when the inner planets were forming, they might be gas giants with similar atmospheres to Jupiter as well, but as it happened, it was well past us and we ended up with a relatively thin atmosphere.
