There’s even a famous
song about it existing, from the movie Casablanca, and everyone knows the movie Casablanca.
We humans know that ‘time
goes by’, time moves on, and space is
where we park the car and hang our clothes. We see time and space as separate ‘things’.
Always did.
Modern Physics suggests
there is no such thing as Time and no such thing as Space separately like that,
but only the-two-together as spacetime.
Can we really understand spacetime without getting into other mysteries of maths and geometry? Perhaps, if we
don’t make the same mistake twice.
We need to
think of spacetime as not some thing ‘inside’ or ‘outside’ something else, something we call the Universe, but of Time-and-Space together as a property of the
Universe.
Now instead of getting all technical (as if I would or could!), Einstein is said to have got the idea for
Special Relativity while going down in a lift somewhere.
Inside the lift, he intuited
that if you were falling inside a lift that was falling, there would be no Space and Time anymore. Can we all imagine that happening? Just going on and on? Maybe we can, but not on Earth. Where then
could it happen?
Only where there is no up and down, no left and right, no backwards and forwards. In spacetime infinite
Universe. Where there is no Space and there is no Time.
