Here is a pretty amazing paper:http://arxiv.org/abs/gr-qc/0412068

Quote:This procedure will throw light on several peculiar features of gravity (which have no explanation in the conventional approach) and
will provide a new insight in interpreting general coordinate
transformations.

Its got to be read to be believed!

A question posed some time ago:Is Gravity an Holographic Effect, appears to be the conclusion?

Vacuum Lengths have also been given an intesting angle(no pun intended)
 


T Padmanabhan's latest paper delves into the peculiar features of gravity and offers a new perspective on interpreting general coordinate transformations. This is an exciting and thought-provoking read, as it challenges the conventional approach to understanding gravity and offers new insights into this fundamental force of nature. By exploring the underlying principles of gravity, Padmanabhan sheds light on mysteries that have long puzzled scientists and offers a fresh perspective on this complex phenomenon. This paper is a must-read for anyone interested in the mysteries of gravity and the ongoing quest to understand the universe.
 
OK, so this has bugged me for a while about the equivalence principle and the black hole information paradox. If black holes "evaporate" via Hawking radiation, then they cannot exist forever. So, from my external perspective, watching the person fall in, they slow down, freeze, and redshift to "nothing," but never cross the event horizon. Does the equivalence principle say my perspective is valid? If it does, is it possible that that person really never crossed the event horizon? The...
ASSUMPTIONS 1. Two identical clocks A and B in the same inertial frame are stationary relative to each other a fixed distance L apart. Time passes at the same rate for both. 2. Both clocks are able to send/receive light signals and to write/read the send/receive times into signals. 3. The speed of light is anisotropic. METHOD 1. At time t[A1] and time t[B1], clock A sends a light signal to clock B. The clock B time is unknown to A. 2. Clock B receives the signal from A at time t[B2] and...
From $$0 = \delta(g^{\alpha\mu}g_{\mu\nu}) = g^{\alpha\mu} \delta g_{\mu\nu} + g_{\mu\nu} \delta g^{\alpha\mu}$$ we have $$g^{\alpha\mu} \delta g_{\mu\nu} = -g_{\mu\nu} \delta g^{\alpha\mu} \,\, . $$ Multiply both sides by ##g_{\alpha\beta}## to get $$\delta g_{\beta\nu} = -g_{\alpha\beta} g_{\mu\nu} \delta g^{\alpha\mu} \qquad(*)$$ (This is Dirac's eq. (26.9) in "GTR".) On the other hand, the variation ##\delta g^{\alpha\mu} = \bar{g}^{\alpha\mu} - g^{\alpha\mu}## should be a tensor...
