According to Einstein’s theories of relativity, objects travelling at great speeds in 3D
space
would appear from an external observer to flatten in the direction of their travel.
This squishing effect happens exactly in line with this model, and is to do with time
dilation.
However, from the person whose travelling’s perspective, they do not flatten, but it is
the rest of the universe that warps. I talk about this in greater depth in another video of
mine, where we can see the effects
of spacial warping in a computer model. From their perspective, everything would stretch
at the edges of their vision, while their
destination would seem further away, which is again what this model would predict.
The only difference is that in this model we’re just exploring a 2D object stretching,
so the stretch is in only one direction, while in real life it’s 3D, which means it stretches
in 2 directions instead. But that is what you might expect, as you turn away from our
conventional 3 dimensions,
and start orienting yourself away from time. But if this is correct, so what?
Why does this matter? If time is truly a direction, then it deepens our understanding of
the universe.
It also raises more questions. What is the force that pushes us ever-forward in time?
Why does it seem that we can never move against it? Although in this model there is no
reason why a vector could not point downwards, in
real life this doesn’t seem to ever happen. This model also answers the question of, if time
is a direction, what is our shape in
time? Does part of us protrude into the past, or into the future?
According to this model, that does not happen. We are flat pancakes in the 4th dimension,
pennies that look round when you look at us
head on, but revealing our thinness when we turn away from you. That’s a strange
thought, but may just be true.
