If you agree with the special theory of relativity, Einstein states the a clock ticks slower if moving faster(physically). That was proven with an atomic clock. Now, I'll assume you understand $${\mathtt{E}} = {{\mathtt{mc}}}^{{\mathtt{2}}}$$, but if you don't, it's Energy (belonging to said object) equals the mass of it, times the speed of light, squared. Energy=Mass*The speed of light, squared. So, Einstein calculated that light moves at roughly 186,000 miles per second.
If you can double the speed of light, or even achieving it, you would most likely reach absolute hot, $${\mathtt{2.55}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{32}}}$$ degrees Fahrenheit, essentially messing you up. But, let's say that you survive absolute hot, and you DON'T die. Einstein's general theory of relativity states that time is different to all observers, so you would't be stopping time for everyone, just yourself, and you wouldn't be even stopping time, just making it seem very slow from your perspective. So you would have to be moving at around the speed of light. BUT WAIT, THERE'S MORE! Time isn't REAL. It's just some stuff made by man to keep track of things! It's not REAL! What I just said above could all be false! There might not even be a past, or a future! Ok, thats enough tinkering with the Matrix for now. Bye.
-Wow, that was deep. I like π.
