“What do cancer research, time travel theories and the possibilities of life on other planets all have in common? For one thing, Paul Davies,” said Steve Goldstein, host of the radio show “Here and Now” on KJZZ (91.5 FM) in metropolitan Phoenix.

Davies, a theoretical physicist, cosmologist and astrobiologist at Arizona State University, where he is a Regents’ Professor, talked about the varied topics during a 15-minute interview Dec. 21.

Time travel was the first topic raised by Goldstein, and Davies replied: “People want to know, can it really be done? And, the answer is, well, maybe.” He explained that using Einstein’s theory, “we know how to travel in the future … just move. You can only go forward in time … this way.”

Davies didn’t want to give too much away on the radio show about time travel, since it is the topic of the annual Sci-fi meets Sci-Fact lecture at ASU. Davies, who is director of the BEYOND Center for Fundamental Concepts in Science, will deliver the lecture at 7 p.m., Jan. 31, in Neeb Hall on ASU’s Tempe campus.

However, he shared with Goldstein, “with something like a wormhole in space, it might be possible to go back in time.”

Other topics covered during the interview were one-way missions to Mars, the importance of continuing to search for extraterrestrial intelligence (SETI) and the importance of imagination to a scientist.

Davies also discussed his current research on cancer, as director of one of the 12 federally funded physical-science oncology centers looking at cancer research through fresh eyes … those of a physicist, rather than a biologist or chemist.
