EINSTEIN’SGENERAL RELATIVITYAND TIME TRAVELWhere would you go?
I’ve Always Loved Time Travel
How We Think of “Absolute Time”
Time is a force of nature separate from us that moves at the same rate for all of us
Sir Isaac Newton’s“Absolute Time”(1600’s)
Yes, sometimes we perceive time moving slow or fast but that’s just a trick our mind plays on us
Time Travel is Impossible!
Einstein Discovers “Relative Time” in 1905
Time, Space, and Gravityare intertwined (not separate)and can affect each other!
Time is relative and can move at different rates for different people! This means your present isn’t necessarily my present.
Time Travel is Possible!
The Time-Space-Gravity Demo
Time(clock)
Space(speed)
Gravity(weight)
How Could You Possibly Test This?
Start With A Ground Clock (stationary, normal Earth Gravity)
Add A Space Shuttle Clock(orbiting the Earth at 17,000mph
+ near orbit microgravity)
Cesium Atomic ClockAccurate to within 1 secondover 100 million years!
Space Shuttle Clock ran slower than the ground clock!Confirming time travel!
So all you need to Time Travel is…
A Really Fast Ship! Super Strong Gravity!OR
