What If You Met a Time Traveler?

With your support we can make our show better! Join our Patreon community: http://bit.ly/whatif-patreon If time travel is possible, why haven't we met a single time traveler yet? And if we did meet one, how would we know they weren't faking it? What would their time machine look like? And how would it operate? Would there be a set of rules for time travelers to follow? And what would happen if they decided to break them? Transcript and sources: https://insh.world/science/what-if-yo...

But without it, we go nowhere." — Carl Sagan What If is a mini-documentary web series that takes you on an epic journey through hypothetical worlds and possibilities. Join us on an imaginary adventure — grounded in scientific theory — through time, space and chance, as we ask what if some of the most fundamental aspects of our existence were different.
