Beer would stay nice and cold in there.

I deem it metal.

neutrinos are smaller than stuff like protons, neutrons...that's all you need to know

anyway, cool pics, must have been cold as hell in there, damn.

Ugh... How anything exist and not have any mass... Physics give me headaches, although I would so love to understand some more.

I believe some of the early quantum physicist said that anybody who thinks he understand this fully is either fooling himself or lying

I'd really love to see what would happen if you locked the guys who made TimeSplitters and Half Life in there with food, water and their game making thingumajiggers.

These do have mass, just very little.

As for photons, which actually have no mass, recall the most famous (and least understood) advanced physics equation ever: E=MC^2. This isn't quite the case for high-speed photons, but energy is also a property that can help to define something. The expanded equation, that is accurate when dealing with things that have a great deal of momentum, does include momentum.

Without too much detail, you can view energy as an intrinsic property that helps to set something apart from something else, like mass, and photons do have momentum by another twist of physics/magic/hoobladoop. Basically, the energy carried by a photon is 'good enough' to make it count as something that exists because energy is in some ways more important than mass.

Actually E^2 = m^2 c^4 + p^2 c^2, so photons have energy based upon their momentum.

The second term is only really necessary for high energy and particle applications. In the macroscopic world, E = m c^2 works perfectly fine, because the momentum ( p ) is small.

[JBroll]

Yeah, that's "The expanded equation, that is accurate when dealing with things that have a great deal of momentum", I was just trying to not give him too much of a headache. Low-energy systems can have their mass seen as energy from that equation, which is the point I was trying to make. Energy makes stuff work, basically.

Yeah. "Energy makes stuff work" sums up the whole idea of energy perfectly.

I just wanted to make it clear that the mass is not mathematically necessary to make energy. I guess that is epic fail, though, since momentum is not exactly the easiest concept to grasp without a strong groundwork.

[JBroll]

"The energy transferred when one thing hits another" is intuitive and not too far off.
