If you could figure out a way to invert all the constants and principles in the universe, then we could relive our past, in reverse. tea cup fragments on the floor would assemble into a teacup then accelerate up into the air and then sit on the table. The universe would play out, right back to it's formative moments. Then you could watch yourself being born, though you would have to wait years for it to render.
I don't understand the physics but I do believe Stephen Hawking disproved this[1]; he said that after entertaining the idea that as the universe contracts time might reverse he concluded later this was wrong.
