Thread: If matter cant be created or destroyed, where did all this stuff come from?

Check this out, I might have pulled this clip off this website that someone posted, but I don't really remember where I found it.

The particles they accelerate in the LHC gain mass as they approach the speed of light (attempting to add more kinetic energy to the particles to find they just keep gaining more and more mass like Xei entailed).

I linked to that video See post #110 just above.

It's a great educational video, with nice visuals.

Oh my mistake bahahaha. I haven't been here for a while, I do appreciate that vid though thanks for the link.

Crap, this thread is old...

As it has probably been stated above, matter and energy cannot be created nor destroyed, but they can be converted back and forth. In nuclear weapons and such, a small amount of matter is converted to pure energy. Scientists at CERN and other facilities are also trying to get matter out of energy...not sure if they've succeeded yet or not.

Nuclear weapons do not convert matter to pure energy, only a small fraction. You would need antimatter and large amounts at that.

In nuclear fission 0.04% of the total mass becomes energy.
In nuclear fusion, 0.03% of the total mass is released as energy.

Yeah, a fraction

Is it that matter/energy cannot be created or destroyed, or that matter/energy cannot be created or destroyed by any way known to mankind?

I feel pathetic that instead of listening to my science professor and hearing about that, Dan Brown told me about it.
