Quantum physics makes my mind do loop-de-loops.
People that study quantum physics for a living feel the same
So when the pulse of light is at the same frequency (wavelength) as the atomic resonance of the super cooled matter (the frequency of the atoms natural shimmy, which in a super cooled state act as a single, massive atom), the time (when measured as the amount of quantum state change as a result of the photon passing through the atomic medium) in which it traverses the atom is less than what it should be, indicating that the photon was not slowed in any way through it’s interaction with the atom(s).
…is that right? did I do an understanding?
So basically the first real recorded backwards time travel
No. The pulse still took longer than light through vacuum. That’s the limit that needs to be broken for any causality violations to happen and that’s the limit that can’t be broken.
