Fast Enough - S1-E23
Corrected entry: At one point near the end of the episode, Professor Stein says to Barry, "That event has an energy level of at least 6.7 teraelectron volts. It cannot be stopped." One TeV is a measurement used in particle physics and is a very small amount of energy, approximately that of a very small flying insect. Hardly a proper measurement for a huge, catastrophic event.
Fast Enough - S1-E23
Corrected entry: Particle accelerators have to be a perfect vacuum in order to work properly, otherwise the particles inside would constantly collide with the air molecules. This means Barry couldn't possibly be running inside, because he doesn't have any breathing apparatus with him.
Correction: As seen in many episodes, Barry's cells can rapidly reproduce new cells even with no oxygen (as seen in season 1 where the man could create a poisonous gas) and Barry survived. Therefore he would not have to have a breathing aid.
Correction: Teraelectron volts measure particle energies, or their acceleration. The power comes from the amount of space the energy is squeezed into. The Large Hadron Collider accelerated protons to 1.18 teraelectron volts, so not much more than a mosquito, but a trillion times smaller than a mosquito, so quite powerful. The energy reading from Stein is over 5.6 times more than the world's most powerful superconducting proton synchrotron, and it's crammed into a very small space, making it nearly unstoppable.
