Hi all,

Would you answer this question for me.

What is the total energy of a proton travelling at 0.999999c inside a particle accelerator?

Thanks

I heard on a TV programme that it was equivalent to an aircraft carrier traveling at 30 knots. :rolleyes: which is , a lot of energy!

But, i think that was for a bunch of Protons in the LHC . Not sure how many a bunch is....

A web page on the Oh My God Particle (http://www.fourmilab.ch/documents/OhMyGodParticle/)claims that a velocity of v = 0.9999999999999999999999951 c equates to an energy equivalence of "an American baseball travelling fifty-five miles an hour."

The total energy of your 0.999999 c proton is about 700 times less, closer to that of your brother playfully tossing a piece of popcorn at you during the football game.

Here: http://lhc-machine-outreach.web.cern.ch/lhc-machine-outreach/lhc-machine-outreach-faq.htm (How much do the protons weigh in the LHC at 7Tev?) the LHC team derive 1.2477*10^-23kgs.

You wouldn't notice that if you dropped it on your toe.

You might notice a very high energy cosmic ray secondary if it traveled vertically through your spinal cord. There's certainly sufficient energy in the trail to create an electrical impulse, and with human sensitivity to sound around a billionth of a watt, I'm thinking you'd notice a twitch,,,though some physiologists on board might have a clearer perspective. pete

Also of note,there's a slight acoustical twitch in ice from showers, either of proton/air secondaries, or of HE neutrinos, but is likely undetectable by torso....which is being proposed as we speak. see:http://www.iop.org/EJ/article/1742-6596/136/2/022053/jpconf8_136_022053.pdf?request-id=28495513-40a2-4a03-963d-ff38161c5fb7
