Of course the speed of the light is C still, but the relative speed of the light beam compared to us, should be greater than C otherwise would not be blue-shift effect. As you wrote: "Each wave crest has a bit less distance to travel to reach you than the previous one so spends a bit less time...

Thanks. Nice big formula set ... The next year will be enough for me to digest and understand all of this. :smile:

What about the blue-shift effect? For me, those 2 things are somewhat contradictory. If I interpret it correctly, the blue-shift effect is created because the speed at which a given object approaching the observer is added to the speed of light beam. Which means that the relative speed of light...

Thank you very much! :smile:

Ok, I'm got it. I'm absolutely wrong. Sorry that all of you wasted your time for it!

I would respectfully note that I wrote essentially the same thing. The difference is that I rounded the measured light speed to 300,000 km/s. Furthermore, I did not refer to SI as it is obvious. Yes, according to wikipedia, the accepted last measurement is: “After centuries of increasingly...

I know all the arguments are true, and most have become proven in practice in the meantime. I'm just thinking loudly, and something weird thing flashed in my mind. Actually does anyone know the exact speed of light? The speed of light was measured in our world, which is limited to 3 dimensions...

Thank you for all the answers. I'm still trying to digest ...

Can someone give a meaningful explanation that the relative speed of two oppositely directed light beams is why only one light speeds? I understand that based on the Einstein relativity theory, the relative speed of two beams is C, because nothing can be quicker than light speed. However it is...

I am a software developer but very interested in physics, especially cosmology and the theory of physics.
