The Physics of Interstellar Travel

Saturday 03:00pm

Panelists:
Prof. Kevin H. Knuth  

It is commonly thought that interstellar travel is made physically impossible by the immense distances involved and that the only possible solutions would involve either faster than light travel or the warping of space-time.  In this talk, I discuss the physics of interstellar travel and reveal that the laws of physics work with any traveler making interstellar travel possible even at sub-light speeds.  Aside from engineering challenges, the main challenge is that space travel is time travel and that interstellar space travelers naturally become time travelers that rapidly advance into the far future.  The limits to interstellar travel are not due to physics, but rather are due to both engineering constraints, and social and societal constraints.  The end result is that an interstellar civilization would look very different from our current terrestrial civilization.
