Time Travel

Afraid of the Dark



Who remembers trying to race against light so you could get in bed before it got dark?

Turned out light was really fast

If only we had a time machine


Einstein’s Great Idea


The speed of light is constant(ly very fast)

If we had very fast spaceships, this would allow us to observe some crazy things
For example
The twin paradox

But we don’t need a spaceship
A regular passenger jet will do
Or even just a tower! (Visual explanation)
