Could there be a totally different dimension not bound to what we, in our limited understanding of space, know as time and space?
I mean, there has to be something… What’s there then? I know we are limited as far as what we understand and we can only come up with limited explanations based on known facts… but again our facts of what’s out there, to the edges, is not a certainty… which opens up the possibility of unlimited theories…
Could our universe be part of a supercluster of universes? Could it be the only universe but after it their is a different dimension with totally different laws of physics etc?…

]]>I understand Pi, but if we have spacetime, and if all the fabric of the universe is part of spacetime than how can even in diameter there be more distance than the 13.8
billion years of the age of the universe? The diameter of the universe could be say 400 billion light years across. The diameter is still part of spacetime. So that would mean 2 galaxies could be further apart in light years than the lifetime of the universe? Which can’t be true because the diameter couldn’t have grown faster the the center of the universe if all of it is collectively spacetime? What the heck
“The shape of the universe depends on its density. If the density is more than the critical density, the universe is closed and curves like a sphere; if less, it will curve like a saddle. But if the actual density of the universe is equal to the critical density, as scientists think it is, then it will extend forever like a flat piece of paper.”

This is why it leads me to believe it’s more like a möbius strip twisting infinitly. If you follow the curving path of a mobius strip it appears your traveling in a straight line along a flat surface forever, when actually your traveling along a curving path indefinitely.
]]>how about the spooky action at a distance and time? quantum stuff is never mentioned in this article though somehow can it be ignored? seems weard. in another article you said the big bang happened everywhere thus if the universe is expanding we can conclude is not only expanding in space but also in time thus maybe this expansion we just observe it as distance and we do not actually measure the time. am i making any sense? it is a space time thus it must expand in both.
how can the universe be flat, expand in the same time and there is no center? seems kind of strange theory. would be like you stretch some paper but all particles will believe they are the center? but big bang theory does not give any center right?
how can the flat universe explain the black holes?
