Nope, your lights and vehicle will be traveling at the same speed.  [/quote]
How do you mean? Yes the headlights are attached to the car, but i'm on about the photons emitted from the headlight. I'm on about the light, not the lightbulbs!!

BlOOp = same speed. The photon travels at the same rate at the speed of light. It doesn't matter how fast you're going, the photon will travel at the same rate. You said it yourself.

Alpha Cent is a twin star system and does not have any inhabitable planets.

WRONG.
Alpha Centrauri is a triple star system: two large stars and a white dwarve, aka Proxima.

no, that doesen't sound quite right. alpha centuri is 4.4 LY |
alpha centari is not the closest star to our own, alpha proxima is,its 2.3 lithyears away. |
i am pretty sure that the closest star is 4.4 light years away, but maybe this is alpha proxima. 2.3 light years is wrong for the closest star, no star is that close. |
2.3 lightyears is too close... i think its 4.4, like PrankishSmart said. If a star was that close to us, the orbits of the planets in the Sol System would ge upset

Alpha Proxima = 4.2
Alpha Centuri = 4.4

The writers really should have done some research on this one. (Maybe they did, and the joke's on us.)
Our galaxy is approximately 100,000 lightyears across. Our stellar system is about 30,000 lightyears from the center. This puts Voyager as far from Earth as you can get and still be in our galaxy.

Quoted from: http://www.what-is-the-speed-of-light.com
"What is the speed of light?
The speed of light in vacuum is exactly 299,792,458 m/s (metres per second)
In 1983 the SI (Systeme International) defined a metre as:
The metre is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second.
When people refer to the speed of light, they refer to the definition above - the speed of light in a vacuum.
The speed of light is normally rounded to 300 000 kilometers per second or 186 000 miles per second.
The speed of light depends on the material that the light moves through - for example: light moves slower in water, glass and through the atmosphere than in a vacuum. The ratio whereby light is slowed down is called the refractive index of that medium.
In general, the difference in the speed of light in other mediums is ignored."

Quoted from: http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question19.html
"A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers."
