I never said that it did not travel at that speed. Only that relative to something traveling at 99% the speed of light the light is not traveling that much faster than they are. It is still traveling at that speed, but not that much faster than they are.
The speed of light, rounded off, is 186,000 m/s, in a vacuum. Correct?
So, for the sake of argument let's leave it there.
Now, if I travel at 1/60 m/s, or .0166666.., the light is still traveling at 186,000 m/s, but it is traveling at 185,999.983 m/s faster than I am. This does not mean it has stopped moving at 186,000 m/s.
It still moves away from you at 186,000 m/s. Just as a truck moving at 70 mph moves away from a car traveling 60 mph at 70 mph. It is merely going 10 mph faster. But it is still moving at 70 mph.
I'm sorry I came off a little belittling. Forgive me.
However, rounded off light travels 3 x 10^8meters/second. I think you're thinking miles/second or miles/hour or something. I prefer metric.
Here's the thing. When you travel let's say 10 m/s. Light travels away from you at 3 x 10^8 m/s. But to an outside observer the light is traveling 3 x 10^8 m/s also... So to you, the moving person, light travels exactly the same speed as too someone who isn't moving... This isn't really a problem because it's hardly noticeable. Everything seems normal.
The problem arises when you travel near light speed. If you are flying in an aircraft that can fly at a constant rate of 50% c (speed of light) and you turn on the head lights (I guess the sun is going down) the light from the headlights will travel away from you at exactly the same speed as if you weren't moving, 3 x 10^8 m/s. For simplicities sake, light
seems to be moving faster than c because it has to escape your speed and maintain its own speed of c. However, to an outside inert observer, the light is also traveling c, and this is where it gets confusing,
not c + 50%c (your speed). As long as you don't accelerate, light will
always travel 3 x 10^8 m/s away from you regardless of your speed.
So, to sum up, if you travel 50% c.
To you, light seems to travel 50% c + c. But to an outside inert observer, the same light seems to travel c. It is relative... I don't really know how to explain it any simpler. You'll have to talk to a Physicist if you want a better answer.
