CERN collider revs up search for cosmic mysteries

"It could also help back up the string theory concept which provides for extra dimensions other than the known four ? length, breadth, depth and time ? and for the existence of parallel universes."

Known 4? More like known 3. We perceive time as passing because we age, and everything breaks down and decomposes, but time is a theory, I don't think there's proof that time exists as a dimension. Time is something we assume to be real, what is time?

Time is the increasing amount of entropy* in the Universe. [* Entropy is the tendency of the universe to have energy migrate from a high energy state, to a low energy state. A cup of coffee does not suddenly become warmer over time, unless time is flowing backwards.]

Time isn't a theory, as we have measured it's effects with respect to gravity. The passage of Time changes depending on proximity to mass, and with respect to velocity - as Einstein predicted. Understanding time, that is the big quest. Why do we remember the past, but not the future?

Thanks for that.

Question...do you believe in 11 dimensions?

Happy to help. The question is, do they believe in me?

It's not 'belief' that is required. What I know about string theory is that is requires the presence of 11 dimension in this universe. That's just how the math works out, if the Math is correct. If the theory and equations are correct, then they exist. There used to be many more dimensions required for the two different expressions on string theory, but a bright physicist named Edward Witten saw that there two theories were just different ways of expressing the same thing.

There are a few theories as to where these dimensions reside, and one of them explains why the Nuclear and Electromagnetic forces are so incredibly strong but only are effective at close distances; and why Gravity is so weak, but operates at such a long distance.

DrCaleb, thanks again for your view, I thought I would stop using the quote thing as it starts to take up a lot of space repeating what's already been said. I am by no means a scientist but I do love it, I so look forward to the future and what discoveries we are yet to make. I regularly visit a science web site (newscientist.com if anyone is interested), and I find it very interesting keeping up with new discoveries.
"We will be focusing this year on super-symmetry, extra dimensions, how black holes are produced, and the Higgs boson. We expect some first results by the summer," said Buchmueller. Really looking forward to any news coming out of CERN this year/summer.

Ditto Newf. I recall the 70's and 80's when particle physics had a big renaissance. Almost every day there was a new particle at some unforeseen energy level.

The LHC and the Tevatron are both doing things that we can only dream of. Did you know the touch screen on your smart phone utilizes quantum properties in order to work? The batteries in your phone and laptop also wouldn't be possible without discoveries that come from high energy physics. Things like this don't just affect geeks, but every day objects!

Watched a BBC documentary What Is Reality or some thing. It was insightful, actually gave me a much better understanding of this quantum stuff. Five minutes before the end buddy explains that it's all about math and the only way to explain it is through MATH. Math = I'm fucked!

Oh I could get in to this discussion, I've heard, read, watched a lot on this subject...What is reality? Most people seem unaware of the world around them. You know what's really f..ked up? And hard to wrap your head around, the world around us is made up of %99.999999 empty space (I can't remember the number of 9's but it's a lot). Everything is made from atoms, and of course the fundamental particles of the atom, and an atom, from everything I know, is made up of almost all empty space, the number I mentioned above. So, everything we know and see is actually not quite as solid as it appears. Maybe DrCaleb can vclarify anything I may have mis-said.

Nope. Quite correct.

Imagine an atom of Hydrogen. Neutron, proton in the center. If they were grains of sand on one of earth's beaches, the electron orbiting them would be a grain of dust on the dark side of the moon. And there is nothing in between.

...Can it be possible that matter doesn't even exist at all? What we perceive as matter is perhaps just another form of energy.

Now you are getting into String Theory there raydan.

How is that string theory? I thought Einstein already said that long ago?

Maybe it's all mental:
