Solar Light System

Samantha Said:

the solar system is moving, is the Light of the sun moving faster than the theoretical speed of light?

We Answered:

It's true that the speed of light is constant no matter what speed at which you or the source is moving. This is a fundamental postulate of relativity, and there is no explination. It's just accepted because our experiments indicate that it is true. You used the formula "lights speed + X = actual speed" this type of velocity addition is called "Galilean". It turns out that speeds don't actually add that way. Far out.

Where is the rest of the energy? Good question. The frequency of the light you observe from the sun DOES depend on how fast you and it are moving. The energy of each photon is given by E = hf, where f is the frequency of light.

I'm looking for projection of solar system to light up on childs wall as a night light?

That eBay thing looks really cool!
