Well, my physics teacher really sucked and I lost interest after a (short) while and we actually never even discussed matters of higher levels.
Why is the Flash as fast as he is? All I know is that his metabolism is super fast as well, but that doesn't explain why he can so easily overcome the wind resistance.
I do remember though that there was a discussion about the acceleration (in particular the warp speed) of the Enterprise space ship, and that in order for the gravity dampers to work the acceleration has to happen first. And if that happens, even the smallest amount of lag would kill everyone inside.
Just watched the last episode of the Flash's season 1. Now with the ancestor of the Reverse Flash dead in the present, doesn't that mean that all the events that had happened in the future before this event will be altered in the sense of no Eddie Thawne, no Reverse Flash, no going back to kill the mother.
I'm not that familiar with the comics, but Barry becomes the Flash in that accident in his lab, so that would mean the explosion of the partical accelerator is bound to happen in either case and that it was built by the original Harrison Wells.
I guess we are back to different time lines then.
