Was the Early Universe 2 Dimensional Spacetime? 309
astroengine writes "According to two theoretical physicists, our current four-dimensional Universe (3 dimensions of space, 1 dimension of time) is actually an evolution from a lower-dimensional state. The early Universe may have existed with just one spatial dimension (plus one time dimension) up until the Universe cooled below an energy state of 100 TeV. At this point, a transition occurred when the spatial dimension "folded" to create 2 dimensions. At 1 TeV, it folded again to create the Universe we know today: 3 dimensions of space, one of time. This may sound like a purely theoretical study, but there might be evidence of the evolution of universal dimensions in cosmic ray measurements and, potentially, in gravitational wave cut-off frequency."

Not far from the truth. You don't even know what big is. [youtube.com]
Holographic Principle? (Score:5, Interesting)
I wonder if this follows from the Holographic Principle [wikipedia.org], which states that the information from the entire universe scales with area, rather than volume. That is, the information inside our universe is embedded in 2-space, not 3- or 4-space.

Obviously the universe was dimensionless in the beginning. I'm talking out of my ass (of course!), but I have come to believe that the form and structure of the present-day universe evolved from an initial state of dimensionless chaotic energy bounded by a single (and not comprehensible, at least not yet) mode of operation which ultimately lead to the separation of that energy in arbitrary but locally persistent ways.
What a mouthful of BS. I still think I'm right, and I look forward to physicists proving me right or wrong in my lifetime.

How does a concept of heat and energy even work when there is no possible motion (how do you have motion with only one dimension?)?

This isn't the first theory about the dimensionality of the universe changing over time. A while back it was proposed that time itself is shifting into a spacelike dimension. [telegraph.co.uk]
