Science Fiction literature is replete with stories of Time Travel. The most famous of these is The Time Machine by H.G.Wells. In that story, an inventor built a Time Machine and travelled ahead in time, slowly at first, then way into the distant future.
It is, however, not only authors who have an interest in the subject. Time Travel is taken quite seriously in the scientific community.
The biggest obstacle to time travel is the amount of energy required.
Now a leading Physicist, Professor Amos Ori has set out a theoretical model of a time maching which would enable folk to travel back in time.
