Well this is a very interesting and deeper

BRADY: If I put my hand in front of the beam at the Large Hadron Collider,

The beam is a hundred meters underground.

PROF. BOWLEY: Well I really don't know. I mean you've got these things coming together

and you would have thought it'd be extremely dangerous.

Somebody would yank you out of there before you could do that.

PROF. MERRIFIELD: That's a good question. "I don't know," is the answer.

PROF. MORIARTY: I don't know the total amount of energy that'd be distributed,

PROF. COPELAND: The beam is sending protons in one direction,

and of course there's a counter-beam going in the other direction.

These protons are going to have an energy of the order,

So it's not a lot, right? It's of one proton.

But the difference is this energy is like

concentrated into a volume a million million times smaller than the mosquito.

Each bunch has a hundred billion protons.

PROF. EAVES: But by the scale of energies that we notice, it wouldn't

PROF. MORIARTY: 'cause the other thing, 'cause I've worked at synchrotrons

if you're giving off synchrotron radiation

because you've got particles traveling very close to the speed of light,

if they're accelerating then you're giving off synchrotron radiation.

PROF. COPELAND: When they collide them together there are something like 600 million collisions

whereas the energy in the individual proton may not be very high,

the total energy stored in that beam is about

That's like the energy of an aircraft carrier moving at 11 knots.

It's suddenly gonna hit your hand, or your body,

whatever you put in. And it's got to deposit that energy.

So it's like being hit by a massive object.

And I don't think you'll survive very much.

BRADY: Because it's just hitting such a small space

won't it just drill the ultimate hole through your hand?

Why would it start affecting other parts of your body?

that's why I was hesitating of course at the beginning,

the beam has a ranges from a width of about a millimeter,

hair's width, when they actually collide the beam.

So they're really narrow when they collide them.

When they're not being collided they're about a millimeter.

So they're going to come in and crash in here.

So I have thought maybe they'll just shoot through, but

but it seems to me that what's got to happen

because it's now hitting a lot of matter.

almost a total vacuum in in those things,

and so all these particles, it seems to me, will just

I thought it might be a bit more dramatic
