As for dark matter, you're quite correct. It is still very much conjectural, though the effects thereof lend themselves to a fair assumption that it does exist.
Only if the laws of gravity are kept as they are - assuming that they are right. Some scientists are actually questioning the laws of gravity so as to compensate for the ridonkulous amount of mass in the Universe that is unaccounted for because of them. One of the more common known of these scientists is Prof. Mordehai Milgrom.
This mass was unaccounted for, so some dudes came up with the theory of dark matter, but some other dudes started to question how "perfect" the laws of gravity happen to be.
Well I highly doubt the laws of gravity are going to change. I could google it but i don't think there is a figure for how many times they have proved them. that said, one of the issues with the standard model of the atom is that the fourth and relatively weak force of gravity does not fit into the standard model at the moment. The Higgs-Boson could Solve this mystery or it could mean that Physicists need to rethink the atom. I think the latter is highly unlikely because every other part of of the standard model has been proven to exist.
I have hesistated to post this with out a reference but if you go and redefine Newtons second law, F=ma, you will need to completely redefine mass, since mass is the proportionality constant.

to be put simply there are many things they want to find out, like the particles that create mass, and particles that are called dark matter, something they think is a life giving substance etc, its not really about just creating a big bang or black hole but also to be able to study particles that have been observed from far away but never actually in an environment that enables analysis etc
New Delhi - An Indian teenage girl killed herself because she feared that a massive experiment to re-create the birth of the Universe would herald the end of the world, reports said on Thursday.
Chayya Lal, 16, from the central state of Madhya Pradesh, committed suicide after watching television reports on how the particle-smashing test in Geneva could bring about doomsday, Indian newspapers reported.
She swallowed unidentified tablets on Tuesday and was rushed to hospital, but doctors were unable to save her.
Chayya's parents said she had spoken of her fears about the "Big Bang" experiment.
"Chayya had asked me a number of times whether the world would end as they were saying on television," her father Bihari told the Hindustan Times.
"We tried to divert her attention and told her not to worry about any great disaster," the Mail Today quoted him as saying.
The Mail said the local police inspector had raised doubts about the reasons for Chayya's death and had vowed to investigate.
The start of the underground test on Wednesday was hailed a success after the Large Hadron Collider (LHV) designed to expose the secrets of the cosmos swung into action.
Scientists behind the project had earlier dismissed fears that it could create either a "black hole" whose super-gravity would swallow the Earth, or a theoretical particle called a strangelet that would turn the planet to goo.
When the machine is fully operational, scientists hope to fleetingly replicate conditions at the "Big Bang" that created the Universe 13.7 billion years ago.
Yes, Newtonian Mechanics is not applicable to quantum physics but that does not make newtonian mechanics flawed. It only means that it is limited. And besides, for some applications, Lagrangian mechanics is much better than Newtonian mechanics It is not applicable to near light speed velocities either

Something has to happen, that energy has to go somewhere.
You know what I mean... They will find out loopholes and various weird things happening. E=(1/2mv^2), add relativity to that equation and it becomes divided by the square root of a negative number if you exceed the speed of light. Or div by zero at c (speed of light).
Eventually they will add to the equation. The speed of light can be broken if you bend space, bring the thing closer to you and move very fast.
Newton said E=1/2mv^2
Einstein said E=(1/2mv^2)/((1-v/c)^(1/2)) IIRC
He added something. I can remember if Newton came up with that equation or not but that's besides the point.
There's probably flaws in my equations. Will the resident rocket scientists and particle physicists please point them out along with my spelling mistakes. I'm using IE, piece of crap.
Whoever came up with the equation, it is flawed even if it's almost correct at low speeds, it's not 100% correct. We need to find out what's really going on if we ever hope to become a highly advanced civilization.

Ok, we did not do Relativity for the Energy Equation, last year but It might help people if I publish the formulae's for some of the relativity equations.
I am trully suprised that any modification is necessary to the energy equation because it is time and path independent.
So what is the actual chance of this thing backfiring and blowing all of us into the theory of a black hole? (Which will be proven to exist, only problem is that nobody will be freakin there to take notes!)
We got pretty good odds. That's like the same chance that you'd win the American National Lotto like 3 times in a row or something crazy like that. If I'm spreading FUD I do apologize, that's what I heard.

Lol. Does she know you are the type who spend your life on the internet
Seriously though. the same phenomena that could generate these black holes happens on an almost daily basis from cosmic radiation colliding with the earth's atmosphere and other planets(?) and scientists have yet to observe a single planet being eaten up from a black hole as a result.

Yes but those collisions don't happen on the same speed/energy scale as that which they will be attempting with the LHC, so you can't really compare them

I honestly don't know what speed cosmic radiation travels at.
