Comet 

A small icy body--usually only a few kilometers across--that orbits a star. Most comets orbit the Sun beyond the outermost planets in an enormous cloud known as the Oort cloud.

Like asteroids, comets are builders' rubble left over from the formation of the planets.

Arrow of Time 

The direction of time associated with entropy increasing, people growing old and dying, coffee mugs breaking, and the like.

The Arrow of Time as hit me again as I watch many things I loved disapear.

Brane 

An abbreviation for membrane. Branes can be in any dimension up to eleven. They are the basis of the M-Theory, the leading Theory of Everything. If we take a cross-section of an eleven-dimensional membrane, we obtain a ten-dimensional string. A string is therefore a one-brane.

One theory is that our universe was created by two branes smashing into each other.

Blue Shift 

The increase in the frequency of starlight because of the Doppler shift. If a yellow star is moving toward you, it's light will appear slightly bluish. In outer space, blue shifted galaxies are rare. Blue shift can also be created by shrinking the space between two points via gravity or space warps.

Red shift is more common than blue shift because most objects in our expaning universe are moving away from us.

Light Year

1. The distance light travels in one year, or approximately 5.88 trillion miles.

2. A figure of speech meaning very advanced.

1. The nearest star is about 4 light years away, and our galaxy is about 100,000 light years across.

2. If alien's exist, chances are they're light years ahead of us in technology.

Many Worlds Theory 

The quantum theory which states that all possible quantum universes can exist simultaneuously. It solves the Schrodinger cat problem by stating that the universe splits at each quantum junture, and hence the cat is alive in one universe and dead in another.

In other words, everything that can happen, does happen (just in seperate worlds). Every possibility plays itself out in one universe or another.

Recently, an increasing number of physicists have voiced their support for the Many Worlds Theory.

Quantum Foam 

Tiny, foam-like distortions of space-time at the level of the Planck length. If we could peer into the fabric of space time at the Planck length, we would see tiny bubbles and wormholes, with a foam-like appearance.

Our universe may have been born out of a sea of quantum foam.
