Since no one seems to have any information on the subject, I would like to asked for others input into a subject I have pondered for some time now. I envisioned long ago a homogenous brane that filled space similar to what these distinguished scholors are hypothesizing...

study of brane decay that results in a brane/antibrane "pair"? I have heard of anti-branes and have a few questions. Has there to anyone's knowledge been any study of brane decay that results in a brane/antibrane "pair"? Is such theoretically possible?

I read a statement on another message board the SR forbides BHs and GR demands them. Does SR forbide Black Holes, if so, why?

They will reach the center between the two at the same time, but since the train is moving toward one it will see the flash of that one first since the spped of light is finite.

Because the speed of light is c and not instantaneous. The same reason that if a person in front of you is running from left to right between two baseball players and they both throw a baseball at the same speed towards the person, the ball thrown from the right will nail the person in the head...

How does the clock "know" this? My reason for asking this question is that as the clock moves from the center toward the surface the energy required to move further increases proportionally and when it reaches the surface it requires even more energy to continue to move away from the earth.

How fast would a clock tick at the center of the Earth compared to one on the surface?

So the slow down due to acceleration is not constant for both masses in an absolute sense. So the larger the mass the less relative time dialation. I have learned something here, thank you very much. Johnny

I know that when a clock reaches c (it can't because it would require and infinate amount of energy) it will stop. So the clock with the greater mass would stop before the one with the lesser mass. Does this mean that there is a lower speed limit for more massive objects at some speed less...

So let's explore a triplets problem. One triplet in on a space station, one is on a highly massive spaceship and the third is on a spaceship the same size as the space station. The two ships take off together traveling at the same rate, say 3/4c. Who would be young, younger and youngest...

You are right, I am missing a major point here. A clock on Earth ticks faster than a clock in orbit around the earth. A clock on Earth ticks faster than a clock on the Sun. My question is that you have two masses in which one is much larger than the other and I assume that from a third...

I understand that clocks move slower as they approach c. I also understand that clocks move slower on more massive bodies. My question is are these two phenomena consistant and cumulative? For example. We have two masses of significantly differeing masses and both have clocks on...

You could build a two stroke engine that uses the heating and cooling of mercury.
