Time Travel Theory and Practice
..."us physicists believe the separation between past, present, and future is only an illusion, although a convincing one." -Albert Einstein.
Time Travel is theoretically Possible. Technically speaking, we all travel in time. We travel through time at a 1 to 1 ratio - 1 fraction of a nano second at a time. The phenomena of moving through time at varying ratios is where the complexity arrives. As per Einsteins Special Relativity it is possible to alter the ratio. Nikola Tesla once claimed that an experimental mishap put him outside his time-frame. He claimed that was able to see the immediate past, present and future simultaneously.
