Have you found it difficult to wrap your mind around the concept of time dilation? Then today’s video should help make it much easier to understand! Professor Mike Merrifield is back with a terrific explanation of the mathematics behind the slowing of time when observing an object moving close to the speed of light.

This is a wrong assumption. If the speed of light is the same in all reference frames you would not see anything move.
This represents the Galilean transformation only. You cannot see a Photon travelling sideways of any descriptions.
This is all just a blind subjectivism. STR is not real. See my website to see how incorrect it is. Light speed is anisotrophic. There is no excuse for scientists not understanding the serious problems in their mind experiments.
Have a look at neuvophysics.com

I think there is another item to contemplate...
Time slows down as you approach the speed of light and time files when you're having fun. So, if you walk slower, do you have more fun or just get more light?

So you're saying that the existing, observed time dilation effects of spacecraft aren't real?
Photons aren't the only thing slowed down by time dilation. A photon traveling in a straight line is just a simple way to visualize it. Look at chemical reactions: chemical reactions are basically just an exchange of electrons, and the electrons themselves must move slower in their orbits if the nucleus they're orbiting is moving at relativistic speed.
Its all implied by the fact that the speed of light is an absolute speed limit in the Universe, and this light limit requires time dilation. You simply can't have one without the other.
Think about this: if a simple body is moving at exactly 1*c*, all of the motion inside of that body is tied up in its linear motion. How could electrons orbit their nucleii if they're too busy moving at the speed of light along the object's path of motion? The body would have no temperature, no electrical conductivity, no internal chemical or electrical reactions of any kind.
Now reduce that to 99.5% of the speed of light. Rather than all of an object's energy being taken up by moving forward, a mere 10th of that object's energy can now be used for things like orbiting electrons and molecular vibrations.
That's all time dilation is: it's just the internal reactions of an object or system being slowed down because the light speed limit itself is limiting those reactions.
