Light Clocks and Special Relativity

You may be aware of 'light clocks' and special relativity.
If not see this site below for 4 and 1/2 minute video...

I believe that the reason it seems light slows down is due to the greater distance the photon has to travel. This is because the object is moving at right angles to the motion of the light clock.

Think about this... Would they get the same result if the light clock ran parallel to the motion of the moving object?

Would love to know your thoughts...

Also, if anyone has any other links to proof of time travel in this area, would love to see them, and whether they stack up to analysis.

Just had another thought...

This seems to work if the object moves in two directions at once (let's call them across and up).

But if the object is moving in both across and up, they are no longer two separate directions, but one (that being diagonal)...

Does this make sense?

i love physics but it seems that i can not access the video so i cant answer you but i would have loved it if you wrote what happens in the video.

We can see light slowing down sometimes through telescopes. Over extremely long distances, as objects such as stars are moving away from us, light is stretched as its wavelength changes. This is known as the Doppler effect, or "red-shift." Technically, when we look at the stars, we are seeing into the distant past. When we look at different, far off Galaxies and stars, sometimes they get a snazzy red tint, this is a result of the Doppler effect. What you need to be more worried about is when there is a blue tint in an image, as this means that the object is coming towards us!
