If time and space are intertwined does that mean time has multi dimensions like space. In space we can move forward or backwards, left or right and up or down, does time have equivalent dimensions… We move forward in time, the past is backwards but what would be the equivalent of left or right and up or down for time?
In: Physics
It’s not that space and time are intertwined but that there is a concept called spacetime. One word and it’s just the one thing. Spacetime in our experienced universe has three dimensions of space and only one of time, so all you can have is back and forth in time.
But what if it wasn’t three to one? Theoretical physics has investigated this and messing with the numbers of time and space dimensions gives universes that don’t work. To be more precise, the rules of our universe fundamentally don’t work and there are no stable arrangements.
