E=mc2, true or FALSE!
Time dilation
Many scientists today
What is time travel?
Moving in time
Travel into past
Travel into future
Time dilation involved (Theory of relativity)
Leave the present
Slow time or speed it up
Bending space time
Has time travel been achieved?
Future achieved
Go 99.99% speed of light for future or…
Orbit in space for future
Faster then light for past
Look into milky way for past
Is traveling into the past easier then the future?
Milky way is past
Can’t change past
Grandfather paradox
Future travel achieved
Past unachieved
Impossible to go faster then light (for past)
Do you believe in time travel? Some scientists do
Some scientists don’t (Du Shenwang, assistant professor)
Future travel more probable
Future has been done
Harder for past
Many ideas to travel
Spacetime vs. earth time
Matter bends space time
Earth drags spacetime
Spacetime is 4th dimension
Faster you go, space time slows (time dilation)
Spacetime is relative
Space and time mixed
Different ways to travel
Black holes & white holes
Cosmic strings
Wormholes
Time dilation
Kerr holes (Like black holes)
Time machine
Conclusion
Time travel into future is possible, according to Albert Einstein and others
Future, yes… past… not yet
Some people believe in it, some don’t
There are many theories to travel in time
Spacetime is involved
Time travel is going on around you
