Quantum Electro Dynamics
I would like to get everyones thoughts on this topic!
its very interesting stuff.

Quantum electrodynamics (QED) is a relativistic quantum field theory of electrodynamics. QED was developed by a number of physicists, beginning in the late 1920s. It basically describes how light and matter interact.

Common sense sorta stuff.

Yeah, totally.

This is more ofey's department. He's the University man.

lol, I know 'QED' a the latin phrase 'quad erat demonstratum'. No idea with the physics thing!

i am fascinated in trying to harness anti matter, can it ever be achieved?

I came to this forum to avoid work. *sigh*

You guys knock yourselves out... . Enjoy.

When you actually have to study this for exams, it's not as fun. Trust me. I got a C for QED. Worst subject ever... .

Well there are four forces of nature, electromagnetism, weak nuclear force, strong nuclear force and gravity.
QED basically is quite accurate being 'i think' 10 decimal places accurate. (Ofey probs will know this topic well!) The only way it can be completly accurate is to get a quantum field theory that includes all 4 forces.

i know its boring for you ofey so its cool,
but i love all this sort of fantasy meets reality stuff,

i know we can't slow down time to capture anti matter, but is there another way it can be possibly done?.

It's not boring, just tedious. The mathematics underpinning it is far too involved for me now.

i just wanna talk about the theories behind it.

i mean once you suck the air out of a structure to form a vacuum whats left?
what are those particles doing?

All I know for sure is that people don't like Light Beer Atoms, Much would prefer the heavier elemental ones for a more enjoyable interaction with the forces of nature
