Thx for the links, Orac. So, the idea is that the highest energy levels allow only 1 spatial dimension, whilst additional dimensions unfold as the energy level drops. In that case, as one of the referenced articles says, planar scattering might be detected at LHC.
Wow, that's something else. Truly amazing stuff. I hadn't heard of it, and it's over a year old already.
From the Physorg link (above):
So the physicists suggest that a future gravitational wave detector looking deep into space might find that primordial gravity waves cannot be produced beyond a certain frequency, and this frequency would represent the transition between dimensions. Looking backwards, it would appear that one of our spatial dimensions has “vanished.”
...The scientists added that it should be possible, though perhaps more difficult, to test for the existence of (1 + 1)-dimensional spacetime. “It will be challenging with the current experiments,” Stojkovic told PhysOrg.com. “But it is within the reach of both the LHC and cosmic ray experiments if the two-dimensional to one-dimensional crossover scale is 10 TeV.”
...the cosmological constant is fine-tuned to fit observations and does not match theoretical calculations. A solution may lie in the existence of energy that is currently hiding between two folds of our (3 + 1)-dimensional spacetime, which will open up into (4 + 1)-dimensional spacetime in the future when the universe’s decreasing energy level reaches another transition point.
