early universe starting as 1 dimension

Migrated topic.
the article suggests that high energy exists in fewer dimensions. This would seem to imply that as the universe spreads out and becomes less energetic, the number of dimensions increases. Especially on very large scales. But they don't describe the function of the extra dimensions. I wonder what a 4th dimension would "look" like to us or if it could be observed at all.

So, high energy means a single point, medium-high means a line, medium means shapes with depth. Whew, it's kind of mind bending to imagine what low energy systems would be like.

Maybe this video can help with imagining dimensions beyond the third. Even though I can hardly comprehend the dimensions after the fifth.

I am by no means an expert on the subject of theoretical physics, but isn't the fourth dimension time? If so, how could there only be one dimension in the beginning of the universe? I can understand if it implies that matter was so dense that it was basically just long strings that functionally only had one dimension, but given that it happened at a certain point in time, I cannot fathom it being less than four dimensions. From my (very) limited knowledge, I can only assume that an explosion like the big bang would spread out in a spherical shape, or at least something similar.

Still, interesting concept.

Maybe the first dimension was time. As this dimension expanded the spacial-extension dimensions emerged.

Hmm i suppose it's true that none of the dimensions are tied to any particular number, so the designation of time as the "fourth" dimension is perhaps irrelevant. Still, it's hard for me to imagine the universe as having nothing but time...it leaves quite a few questions unanswered, most obvious of all "where did matter and energy come from?", though I suppose the same question remains true for the more commonly accepted theories as well.

Interesting ideas :d
