The discussion centers on the hypothesis that the universe's Big Bang may have originated as a one-dimensional construct, evolving into a two-dimensional form before developing into our current three-dimensional reality. Key references include an article from Live Science and a paper on arXiv (arXiv:1304.6444) that explore this concept. Participants highlight the speculative nature of early universe theories, noting that causal dynamical triangulation (CDT) offers a background-independent geometric framework compatible with general relativity (GR) and quantum mechanics (QM). The conversation emphasizes the need for empirical evidence from high-energy physics experiments, such as those conducted at the Large Hadron Collider (LHC).
PREREQUISITESAstronomers, theoretical physicists, cosmologists, and anyone interested in the foundational theories of the universe's origins and dimensional evolution.
scimeister said:Was the beginning of the univeres's Big Bang, a one dimensional construct which then formed into a two dimensional form and later, our three dimensions with time?
While I'm not aware of dedicated studies, I think the LHC experiments would have noted if high-energetic (~1 TeV) 4-jet events would be very planar, as predicted there. And the cross section is not falling with energy, it is rising.Dale said:Interesting. I was not aware of this. A better reference is probably here:
