I understand that modern day Physics allows for travel into the future, but not the past. I understand that time slows down the closer and closer you get to the speed of light, so that you never exceed that limit. But what if you meet it? I know because of the laws of Physics, you couldn't meet it, only 99.99% of it, but what if you reach 100% the speed of light? I understand this violates the currently accepted laws, but would time completely stop for the observer traveling at 100% the speed of light? Because any slight movement of the hand, or head or any ligament would then exceed the limit... Again, correct me if any of my understanding is wrong, I'm relatively new to Physics and I really enjoy it.
