The speed of light has been measured to be 299 792 458 m/s. Now, the Solar System is traveling at an average speed of 828,000 km/h (230 000 m/s). Summing up the numbers we get close to 300 000 000 m/s
Does it mean, that the speed of light can be actually a relative number based on the movement of the source?
Does it mean that it IS actually 300 000 000 m/s but is calculated incorrectly due to sun moving round the galaxy?
