	Quantum Consciousness
		Penrose, 1989, 1994) is the random procedure that is adopted by physicists in their descriptions of the quantum measurement process.
		Penrose (1989; 1994) has contended that, at a deeper level of description, the choices may more accurately arise as a result of some presently unknown "non-computational" mathematical/physical (i.e., "Platonic realm") theory, that is they cannot be deduced algorithmically.
		In the lowest of the three diagrams, a bifurcating space-time is depicted as the union ("glued together version") of the two alternative space-time histories that are depicted at the top of the Figure.

	Penrose diagram
		A diagram (named for Roger Penrose) that shows the global causal structure of a spacetime.
		It is a spacetime diagram in which all light rays are shown as traveling at 45° and in which, therefore, all particles with mass are shown as traveling on trajectories that lie within the light cone which sits at every point in the diagram.
		A Penrose diagram allows even infinite spacetime to be represent finitely by means of an appropriate change of coordinates.

	Roger Penrose's Gravitonic Brains:A review of "Shadows of the Mind" by Roger Penrose
		I have such a "Penrose," and an Omega for it, in a file, though you, of course, are utterly incapable of absorbing it, let alone believing it.
		The reasoner's power was greatly enhanced by a numeric "diagram drawer," which could, for instance, find the distance between points by taking the square root of the sum of the squares of coordinate differences.
		Numeric roundoff error allowed diagram calculations to show equal segments, angles and areas to be unequal, or vice versa, and to obtain different results for the same diagrams constructed differently.

	Beyond the Event Horizon, BlackHols
		Professor Roger Penrose of Oxford University has developed a special type of space-time diagram that is very useful for representing the solutions of fl hole equations (12).
		The additional singularity, marked as past space-like singularity on the diagram, is what is known as a white hole.
		Figure 8 is a Penrose diagram of a Kerr fl hole.

	Kerr black hole
		On leaving the fl hole you would find yourself either in a region of "negative space," the physical meaning of which is unclear, or in an entirely different universe.
		The Penrose diagram to the right, which shows the internal structure of a Kerr fl hole, makes this clear.
		The dark blue path is of an traveler coming from the past in universe #1, crossing the outer horizon then the inner one, avoiding the singularity, crossing the horizons again, and finally emerging in another universe.

	Gothos: Jillian's Guide to Black Holes
		Spacetime diagrams are all well and good for standard static fl holes.
		Roger Penrose developed a different kind of spacetime diagram for dealing with the more complex nature of the charged and rotating fl holes.
		Where the spacetime diagram projects off into infinity, the Penrose diagram ends in clean, neat pointy lines.

	Penrose Diagram (Site not responding. Last check: 2007-10-19)
		Often in General Relativity one uses the Penrose diagram to describe the causal structure of the spacetime.
		The major feature of those diagram is to put the infinity at finite position and at the same time do so such that the null geodesics are preserved (we conserve the structure of the spacetime).
		The interest in this diagram is that an asymptotically flat spacetime will have the same structure as infinity and therefore the same diagram at infinity.

	Re: This site is immense.
		He uses a diagram that I have seen before in several places - a Penrose diagram of a fl hole that has been replicated to tile a plane.
		Kip Thorne said that it was theoretically possible to travel from reigon to reigon on such a diagram, passing from flat spacetime, through the event horizon in one reigon, and back out to flat spacetime in another reigon.
		If, for instance, the correct tiling was on the surface of a cube or a sphere, then the path would eventually return to it's starting point in the original flat spacetime.

		You can project the surface of the Earth onto a 2-d sheet as well, and it's useful for certain purposes, but you lose the information that it is possible to sail from California to China without falling off the Edge.
		That's why I'm suspicious of the idea that you could travel from reigon to reigon on a Penrose diagram ad infinitum (assuming that you could really avoid the singularities).
		I suspect that by simplifying things too greatly, the Penrose diagram suppresses the information on how the various reigons are actually connected around the edges.

	Definition of Penrose diagram
		In theoretical physics, a Penrose diagram (named after Roger Penrose who invented them) is usually a two-dimensional diagram that captures the causal relations between different points in spacetime.
		The slanted lines under the angle 45° correspond to the light rays.
		Locally, the metric on the Penrose diagram is conformally equivalent to the actual metric in spacetime.

		It is based on one of the aperiodic tilings using "kites" and "darts" due to Roger Penrose.
		The following link shows an enlarged view of the quilt.
		The following (not-to-scale) diagram gives the details necessary to construct the kite and dart shapes (the P2 tiles) used in the quilt, if you want to construct them yourself.

		You believe that the magnetic field we observe emanating from the coil made by Naudin is abnormal because of the non-orthogonal manner of the windings?
		Ideally, the coil should be wound in the manner of the Penrose diagram of the Hopf fibration of the twistor on S3, e.g.:
		Sequentially, the layered windings would look like the following sequence of drawings:
