##### How much does time slow down inside the LHC?
« on: 14/10/2009 09:30:03 »
Mick Pletcher asked the Naked Scientists:

How much does time slow down relative to the electrons inside the LHC at critical velocity?

What do you think?

It's not what anyone of us thinks. Appropriately give the transformations the equations require.

The LHC is going to be firing protons at each other at high velocities.  You can go through the relativistic math, but the gist of it is that fast particles have a "Lorentz factor," which measures how many times slower time goes for the moving particle than a stationary observer.  For the LHC, this factor is 7460, so time travels 7460 times slower for the protons than for us.

I'll calculate it for you:

Assuming that we are talking about the general mass of the proton, we would find a 7000 change in factor for a proton has a 7Tev generation of mass-energy, the calulation of rest mass comes to the above value when the original question is analysed.

Mr.Scientist:  The 'What do you think?' phrase is added by the forum software, not the original poster, so I wouldn't waste your time trying to criticise it.

Also, you should really read what other people have posted before you post your own answers, as they may be redundant.  If you had read JP's post and looked at the link that explained the maths you would have seen that the question had already been adequately answered.

Just another thought.
I have a problem stating that the whole universe slows down relative those electrons. Considering the amount of high energy particles existing we should be standing still if so?

Are we??

Yes, it was a joke
I'm sort of bored presently...

...
"After traveling one light year, the particle would be only 0.15 femtoseconds—46 nanometres—behind a photon that left at the same time."

And JP, why so slow?

Speak up! I have seen no answer but mine. I have given a numerical answer.

What on earth are you on about?
jpetruccelli gave a numerical answer (7460) before you did.

Presumably you also missed the post by LeeE telling you to look to see what has been posted.
You really need to be more careful.

I don't think i originally read any of the responses.
