That’s too bad. My neighborhood is going stronger than ever. All my neighbors are super into Halloween and we all go nuts with decorations and I give out full size bars too. Rumors spread amongst the children and more come to our neighborhood each year.
At 1/100 speed, light would be so redshifted that you wouldn’t be able to perceive it. However, some X-rays (1-10nm) would be redshifted into the visible range (400 to 700nm).
I guess this means you would have x-ray vision. But you would see little to nothing since our environment normally does not include significant levels of X-rays.
