New 52 Flash can run FTL right?
Well, I’m not actually sure it’s ever been stated exactly – but from this (absolutely amazing) ‘respect thread’ for the Flash of the New 52 we can see a collection of examples of his speed. The Tokyo evacuation certainly sounds like it would have to be pretty up there, not to mention the stuff above femtoseconds…
- Flash is able to outpace Darkseid’s Omega Beams. He’s able to eventually escape them by phasing through a Parademon, causing the beams to collide with the Parademon, detonating.
- He repairs the city all while having a conversation with his therapist, without the therapist even knowing he left the couch.
Speed During Combat
Speed Mind and Reflexes
The Flash is able to greatly speed up his brain’s processing speed and reaction speed.
- His speed mind allows him to process information around him all at once to the point where he can almost predict the future. He can determine every possible outcome and act to make the correct choices.
- His instincts and reflexes allow him to react and move the femtosecond he feels even the slightest changes in air pressure. According to wikipedia, in 1 femtosecond, a ray of light travels only 0.3 micrometre, which is the unit of length used to measure cells and bacteria.
The Flash is able to pull things behind him in his slipstream
As I said above, all the credit has to go to /u/FriendlyFapper over at /r/respectthreads and I suggest that anyone even slightly interested in the Flash should check out the whole post which contains a HUGE amount of info, all with examples like above!
Hope this is helpful, OP! I know it doesn’t specifically say he can move faster than the speed of light and I don’t have time to do the maths right now but hopefully it is useful to you :)
