- And so we need a stronger force to keep the plasma together to confine it.
- The stars are not just physical, distant, abstract balls of plasma or gas.
- That gives the plasma enough time to try to make fusion happen.
- OK, so that explains the thruster and the plasma.
- Even in a gas, there's still there's still bonds, but when you get to plasma, they completely break free.

Etymology
Plasma takes its name from the same Greek root for 'something formed', and scientists used it for the hot, ionized gas because that glowing gas looks and behaves like a single 'formed' sea of particles that carries free electrons and ions, just as blood plasma carries cells, which is why the word fits this state of matter.
