Stephen Hawking Looks At Space Exploration, Time Travel

Stephen Hawking is one of the most intriguing men alive today as well as one of the most intelligent. Hawking is now almost completely paralyzed by Lou Gehrig's disease. Despite his disability, Hawking said he has lived a full life. When he speaks out on a subject, the world listens. He speaks out about space exploration in the article below.

Humans must continue exploring space, if only for the romance of it, and time travel should be possible, but engineers will have to figure out a way to warp space-time to be sure, famed physicist Stephen Hawking says.



Hawking spoke out on those subjects and others in a Sunday interview with PARADE Magazine to discuss his new book 'The Grand Design' with Caltech physicist Leonard Mlodinow.


In the interview, Hawking said he supports the continuation of human space exploration.

Robots may be good at gathering data, he argued, but they shouldn't entirely replace people in space. Seeing astronauts floating around in all that vast blackness is inspiring, and people need inspiration, he added.

"Science is not only a disciple of reason, but, also, one of romance and passion," Hawking told PARADE.

On paper, time travel should also be in cards because of Albert Einstein's general theory of relativity, which allows for the potential to warp space-time so much that a traveler could leave Earth in a rocket and return home before he or she ever departed, Hawking said. Of course, that means you have to be able to warp space-time, which is pretty tricky.
