Schematics of the House
Platohagel: Socrates saids,”dimensions as different rooms in a vast house.” I wonder, does dimensional reference made, fit with current physics extrapolation. Socrates: Ah, dear Platohagel, let us inquire together as if walking through a garden of thought, pausing to inspect each flower of concept. Socrates, were he to speak of “dimensions as different rooms in…

Illusions of Grandeur?
Illusions of Gravity Three spatial dimensions are visible all around us–up/down, left/right, forward/backward. Add time to the mix, and the result is a four-dimensional blending of space and time known as spacetime. Thus, we live in a four-dimensional universe. Or do we? Amazingly, some new theories of physics predict that one of the three dimensions…

A Holograpical Universe
Plato likened our view of the world to that of an ancient forebear watching shadows meander across a dimly lit cave wall. He imagined our perceptions to be but a faint inkling of a far richer reality that flickers beyond reach. Two millennia later, Plato’s cave may be more than a metaphor. To turn his…

A Conformal Field Theory Approach?
Using the anti–de Sitter/conformal field theory correspondence to relate fermionic quantum critical fields to a gravitational problem, we computed the spectral functions of fermions in the field theory. By increasing the fermion density away from the relativistic quantum critical point, a state emerges with all the features of the Fermi liquid. See:String Theory, Quantum Phase…

Blackhole Information Paradox
What good is a universe without somebody around to look at it?Robert Dicke John Archibald Wheeler (born July 9, 1911) is an eminent American theoretical physicist. One of the later collaborators of Albert Einstein, he tried to achieve Einstein’s vision of a unified field theory. He is also known as the coiner of the popular…

What is Happening at the Singularity?
WEll, some of the commentors like myself are not worth counting?:)Thanks for keeping it interesting Clifford of Asymptotia. I hope you won’t mind the following quotes for consideration.( it was considered spam) so I reprint it here. Quantum geometry differs in substantial ways from the classical geometry underlying general relativity. For instance, topology change (the…
