Traveling
through Space & Time
with Einstein

Without Einstein
Series
How
do Einstein’s
discoveries both constrain
and enable space travel and time travel?
After
you have enjoyed the broadcast, get the book! All of the information
presented here, and more, can be found in World without Einstein

Time
travel to the future is easy, if you can afford the fuel costs.

Shortcuts
through wormholes are “pipe” dreams that rely on fanciful “negative
energy.”

Everything moves through spacetime at the speed of
light. The faster something moves through space, the slower it moves
through time.
