Time travel: This physicist wants to build a time machine05:42
When Ronald L. Mallett, a retired theoretical physics professor, was 11 years old, he read H.G. Wells’ famous classic, The Time Machine, a book that he said changed his life. He decided he would figure out how to build a time machine so he could see his deceased father again. Nowadays, Mallett, who is an expert on Albert Einstein's theories, still insists that time travel could become a reality.
