"The World As A Hologram" - Prof. Raphael Bousso (1 of 3)

Because the sources of gravitons are subject to inertia and gravity is possibly bound to electromagnetism at the higher end of the energy spectrum, there is likely no causality violation necessarily involved in gravitons being slightly superluminal, IMO.

Supposing there's a random sea of gravitons and each is either raising space a bit or lowering it, where lowering it on a 2-d model universe matches the elastic-sheet model of gravitational potential, while the full raising/lowering cycle for each graviton is in lightyears. I assume in the lower limit a lightspeed propagation of gravitons and a source always emits gravitons at the positive maximum of the cycle. A spectrum of gravitons is possible, and I'll suppose gravitons can form into light.

For "patterns in nature" useful in explaining quantum gravity, how about ring galaxies such as Hoag's Object? I'm guessing the ring diameter is defined by ultralong-wavelength core gravitons, with the ring sitting on the boundary between positive and negative gravitational phases, giving 3/4 a wavelength between ring and core, for a graviton wavelength of about 75,000 light-years.
Seems to me the core+ring form arises by simple evolution from a highly random distribution using this form of QG.

why does he stutter al the time? is this his first lecture? does he need mommy to hold his hand?
one would expect some eloquence from a mother foking profesor, shit, profesors have gone to the dogs

Maybe he has a speech impediment asshole. He is a professor in physics, not in public speaking, or the english language

In some sense man is a microcosm of the universe; therefore what man is, is a clue to
the universe. We are enfolded in the universe.
David Bohm

Very clear exposition of a complex and difficult concept.

fascinating video incidently!! :)

Hmmm, moving avatars are clever, but annoying. Can't wait for the novelty to wear off so that they are no longer used and, therefore don't detract attention from the subject matter (or make u feel queasy) :)

If anybody is wondering, the symbols written using atoms are in japanese. They are pronounced "genshi"（原子） - which means atom or atoms(there is no prular form for nouns in japanese)
