Lecture no. 21 from the course: Life in Our Universe

Space Travel—A Reality Check

Taught by Professor Laird Close | 32 min | Categories: The Great Courses Plus Online Science Course

In this mind-bending lecture, review the obstacles to space travel and consider their theoretical solutions—from combining matter and antimatter into energy, to taking "short cuts" via warp drive and wormholes.
