Light does slow down when going through matter. The denser, the slower (opposite of sound).

[incog-nito]

Is that from the perspective of an observer? Or the guy holding the flashlight? Or both?

From any inertial reference frames, no matter what velocity you''re at, the speed of light is constant.

[incog-nito]

Maybe its the same way with light.

It''s not. Sound depends on the matter that it travels through. The more dense the matter, the faster the speed. Light is totally independent of that. It''s always constant whether you''re going forward or backward. It''s one of those strange properties that''s kinda hard to comprehend.

''The speed of light is fixed, no matter if it''''s from a standstill or from a speeding car. You cannot go faster that it (at least from what we know at present).''

When yer listening to a train go by and that whistle sound goes from high pitch to low pitch, thats because sound is speeding up as the train approaches you, and slowing down as the train moves away from you. Maybe its the same way with light.

But the light from a headlight of a car going 100 km/hr is going 300,000 km/sec + 100 km/hr.

''The story has merit. Publish it''

Thanks. :)

[william2970]

Or it could be 300,000 km/sec - 100 km/hr.

[incog-nito]

If you''re traveling at 99.9% the speed of light, you wouldn''t be in the same "form" you''re in now, let alone holding a flashlight and using it. There wouldn''t be a "you" to speak of.

[william2970]

''(grin) That would mean that ''''light had no speed limit, Right?''

It would mean that 300,000 km/sec was the speed of light from a point of origin standing still. But the light from a headlight of a car going 100 km/hr is going 300,000 km/sec + 100 km/hr.

I have a question for you; If you are traveling at 99.9% the speed of light and you turn on a flashlight and shine it in your direction of travel, "What happens to the ''light'' it emits?"

I firmly believe that ''we'' aren''t the only ones nor even the ''first'' ones. The GOD I know is big enough to have many (projects?).
How about cross-dimensional existance?

It wouldn''t matter when they met us, We are so backward we will try to control them and when they resist we will fight them and then they will destroy us (rightfully so)

[whitemale08]

we tax theirs). In the end, everything we buy costs so much more we have to raise wages for the automakers and everyone else. Wages keep going up, products get more expensive, Sounds like the 70''''s all over again, 20% interest rates on new homes.

that''s what we need, a return to the high-paying manufacturing jobs of the 70''s.

What made the economy so bad was the abandoment of the gold standard and the Bretton-Woods ''fixed-exchange-rate'' that Nixon stupidly did back in ''72.

Had he not did that then we would''ve had those high-paying manufacturing jobs without high interest rates and full prosperity like in the 50''s and 60''s.

It''s the ''debt-based'' economy stupid.

Begin Part (2)
Now the planet is so parched that nothing can grow. Billions have already died and now they have only a few hundred left to propagate the species. Then they all boarded the only means of escape and rocketed into the skies hoping against hope that the third Planet might be able to provide a place to live. They all vowed with one voice to "Never destroy their world again". God slumped and said to himself,"WANNA BET! and a tear fell as he looked at Mars and saw the red dust covering all he had made for them?"
