The actual experiment won't take place until mid October. They've turned it on and tested without particles colliding so far.

Firstly – congrats on a wonderful site. I love all things science fact related, even with my very limited knowledge, and this site puts the gobbledegook into words I actually understand!

Right, at the risk of being branded one of the 'unclean' I have to admit I am VERY worried about the LHC being in operation.

I'm well aware that the world won't actually end tomorrow/today (Wed 10th Sep 08) as they're only doing the preliminary tests and aren't actually colliding anything yet – but I'm getting increasingly worried and may just be worried enough by the proposed collision date in October 08 to explode.

I've seen a lot of articles that have said there's very little danger of anything negative happening as a result of the LHC – but what of that small chance that something negative might happen?

I love science, I love technology and I'm well aware that experiments must take place in order to further our knowledge, understanding and application – however very, very few tests have any chance at all of wiping out the human race – be it immediately or over time.

With two court cases attempting to stop the LHC being switched on thrown out of the European Court of Human Rights, it looks as if there's no way to stop it.

My worry is that these scientists, regardless of how good they are, are playing with MY life – and I like it just the way it is.

Oh and don't get me started on the whole 2012 thing, that scares me too – regardless of evidence for or against – as does any notion of the world ending before I'm 80 as we can never be totally sure.

Within the cathedral rooms where the collision occurs is very sensitive equipment (obviously to capture information on sub-atomic particles); if there was a great deal of energy from this process… colliders would only be good for one use, and this obviously isn't the case. They would also have to create everything to be 'explosion' proof… again, they do not have to.
The colliding items are thousands of times less massive than a spec of dust. Even going 0.9 the speed of light, there isn't going to be any great BOOM of energy; and certainly not enough to create a black hole.

I think…. we are safe!

…I'm not even sure where you picked up the electromagnetic part of whatever craziness you are talking about; unless you are somehow trying to feed in Classical Electrodynamics…so I'll attempt at an answer which may be in the ball park of whatever crazy reference you used.

However, lets get to WHY someone might not use the laws to perfection. Every first year physics student knows Newton's laws combined with gravitation and classical electrodynamics should not be used under certain circumstances; like high speed (in reference to special relativity… due to the Lorentz factor which must be considered…along with others), strong gravitational fields and of course very small scales (which drove Einstein nuts anyway; quantum mech was not a love of his).
I won't go any further, you can look up anything you have questions on based on what I've stated so far.

Not sure what your hatred for physicists is, but you should at least have a better grasp of things before you go around saying how idiotic a group of people are.

I mean seriously… if a famous physicist used something for some reason, there is something behind it you probably aren't getting.

Good thing we have you to catch these mistakes that the people that spend their entire lives studying this stuff so flagrantly make. Next, would you please tell all the brain surgeons how they can get electrocuted by cutting into electrically charged tissue (via firing synapses) with metal scalpels… (…genius…)

"Newton said it takes 3 derivatives to completly define motion. Maxwell and Einstien just used 2 in current electromagnetics and special relativity.
velocity & acceleration.

The 3d derivative is expressed as L/T�, or variations of acceleration with respect to position (statics).

And scientists wonder, why so many phantom particles, just using 75% of overall motion in
their flawed theory colliders.

Wow prime – with but a few cunning strokes of the blog-comment pen, you've managed to demonstrate how laughably inadequate our understanding of the universe is, seemingly based vaguely on the work of a scientist who lived hundreds of years ago. I was blind, but now I see! It's all about the third derivative!!! I just wish I'd thought of taking that elusive next step in physics, and differentiated an expression for the displacement of a particle not once, not just twice, but indeed – thrice! Thrice Einstein you moron – not twice. Get that through your thick skull.

Excuse my ignorance, but maybe you could demonstrate how the the derivative of acceleration wrt position (statics) suddenly makes all of these problematic phantom particles that we keep finding with our "flawed theory colliders" disappear…

I am from galaxy where we were also told
"crank the mother up already —-, THERE'S NOTHING TO WORRY ABOUT ."

Thats why I'm here !

I love these super intelligent scientists that know 100 % of Nature – God – the iniverse – quamyum particles -bedrock of it all .

One thing that puzzles me is if they understand everything in Nature 100% that means they should be able to describe it by mathematics 100%

Then why do they have to build the collider LHC in the first place.

Its like a paradox .

trust me compadre – I've been there already

People that believe in the LHC being a threat are in the same vein as thinking global warming, NASA faking the moon landings and the 2012 doomsday prophecy are real.

Get a life.

Hey Ben everythung is connected and so the energy involved in such a collision would be infinite, in an invinite universe such collisions would happen all the time relesing infinite enrgy, such as found in the LHC V2. which will generate a black whole devouring the pkanet this must stop.

DaViD 2012.( Not drunk)

Have 2 mosquitoes ever collided? Have studies been done on the amount of energy released in mosquito collisions?

It makes me feel good to read your article Nancy, I feel a bit more at ease. :[

But what's next, SLHC (Super large hadron collisionator)?

T_T

But, I hope this LHC project will be a positive step for humans.

What a pair of laughable and transparent frauds they are!
