I am a Comp Sci, Physics and Mathematics Major that works out of the Air Force Research Lab in a summer intern position. Right now I'm doing a lot of work with X code and Objective C, but also do some work with Java and Matlab.

That isn't so much to say it doesn't exist though. There is a similar senario with a faraday cage that gives its interior electric shielding from the surroundings of the cage. This prevents the inside of the cage from getting any information on the electric field outside the cage. The sheilding however only works in one direction, as the shell (if spherical and ideal) will take on a universal charge equal to the net charge on its inside. In this setting information can travel in a single direction, even though the inside cannot be effected by the outside's electric fields.

A bit misleading, Dark Energy is not thought to be related to Dark Matter, but is thought to comprise something like 72% of the universe. Basically this expansion of space is speeding up exponentially, to the point where our known universe will take on a "minimalist" appearance. Eventually we might only be able to interact with our local galaxy cluster, then eventually just our own galaxy, solar system, planet, etc, until matter itself is ripped apart. Hence the "Big Rip".
