i mean 4d of space and 1d of time.

In a nutshell it says that in a super high energy system, like lets say right after the "big bang", lower level dimensions would of been possible. even if for a small amount of time. This is how i got to the idea if we had a dimension of 0 with infinite energy that move into 1d of space and 1d of time, it would decay into a 3d universe.

do you have any idea or guess as to what a 4d plane would look like to us? we will say a 4d sphere or would it just be indistinguishable from a 3d sphere to us?

Thank you for this info I hadn't come across something like this, Please ignore previous statements. Doesn't the CBR (Cosmic background radiation) show that the universe had to have some kind of start? Also what do you have to say to the "vanishing dimensions" concept that has been floating around

No i meant why dose there need to be space-time in the first place, from my understanding of Special relativity, Space-time only exist because the fact that dimensions exist, so why would you NEED space time at all. Wouldn't it just start when the universe went from 0 to 1 or more dimensions? Or are you stating that because in a 0 dimensional space with out space-time nothing could happen? In which case what is your view on how the universe started?

There doesn't need to be unless you can show me a reason there dose have to be.

In a universe with 0 dimentions the speed of causality can be infinite. with infinite "time" anything can happen

What would one expect to see if they were inside of a 3D object that was slowly turning into a 4D object? This is a little broad I am aware. But to be honest I wasn't really sure where to start on this one. The reason I want to put this out there is that the more I grasp some of the theoretical side of science and the maths, I'm starting to see a trend to the possible max speed of causality and the number of dimensions. This brought me to what if Dark energy is an energy that slow's Causality by increasing the dimension count. Please let me know how wrong I am but remember the original point of the thread.
