What about the ? ...People have done studies in outer space of astronauts and how long they could survive in the vacuum... That information say that … - Suzie Sheehy

So what is ? It's energy in the form of moving particles or waves, emitted by an atom or another body as it changes from one energy state to another. That's the official definition.

They developed this machine which was only about this big [~1 meter] and they used ultra-lightweight materials, and it only weighed about 50 kg. So compare that with a 27 kilometer long ring. ...It was only low energy but they... sent it up in a rocket and they actually tested it in space and brought it back down... and they tested it again on earth, and it still worked, which I think is an incredible feat of engineering... [P]eople really haven't heard of this experiment... It's called the BEAR (Beam Experiments Aboard a Rocket) project in 1989, and I have a contact who worked on it...

[Y]ou may have seen... when the LHC was in the news, diagrams that look a little bit like this. These are called s after the famous physicist, Richard Feynman... [W]hat... most of my colleagues in particle physics do, is they take this [full Standard Model] equation, they figure out which particle's interacting and how: what's coming in, what coming out. They do twenty-one pages of calculations, and they come out with a number that is the probability of that interaction happening... [D]epending on which particles go in, you choose a different term that corresponds to those, and which particle comes out, you choose a different term that corresponds to those. Turn the handle and you get your result out the other end. I just taught you quantum field theory in about 2 seconds.
