In Algebra 2 back in high school, there was a math teacher that taught at Princeton who mentioned that if pi were 3, we could be talking about time travel and also travel through dimensions.
Why would pi being 3 and instead of 3.14159.....etc etc allow us to be able to think about traveling through time and dimensions?
A false hypothesis implies anything.
If you have fourteen fingers, then there is an invisible purple dragon in my garage.
Pf: The only way this can be false if somehow you have fourteen fingers and I don't have an invisible purple dragon in my garage.
But that can't happen because you simply do not have fourteen fingers.
So this can't be false. So it is true. Every time you have fourteen fingers (all zero of the times) were also the zero times I has an invisible purple dragon in my garage.
And likewise every time $\pi =3$ happens, time travel exists.
