Ronald L. Mallett, Ph.D. is a professor of physics in the University of Connecticut.
Well… to me it was quite surprising that this fellow has devoted his life to Time Traveling. He also showed his theory in CNN as well.
Though never heard of him; but still not late to know about him and his work. I just went through a couple of documentary videos in youtube and have come to the conclusion of my previous funny experiment that no one from future can ping me until and unless there is a time machine switched on. The timeline in which the man from future can come back is the span from the moment when time machine is switched on till the time of that man in future; and the time machine should remain on in between. WOW, great perspective. Still, it was quite interesting to know about him.
