Is Time Travel Possible?

NASA Space PlaceEvery science fiction fan has pondered the weird implications of time travel. Can you travel into the future and find out the winning Super Lotto number -- then come back and buy a ticket? Would doing so be cheating the laws of physics (to say nothing of ethics?) Astrophysicist Marc Rayman toys with such ideas in this Space Place Musings Podcast. Go to http://spaceplace.jpl.nasa.gov/en/educators/podcast/ to subscribe to these Podcasts. Or listen now to this and the previous Podcasts on your computer or read the transcripts.
