Does Time Dilation apply to Sunlight Traveling to Earth?
It takes approx.8 minutes for the sun's light to reach the earth (depending on the earth's location at any given moment).
But, how much time passes on earth during the sunlight's ~8 minute voyage to us, seeing as time passes at a different (and slower?) rate for anything traveling quickly (especially 186,282 miles per second) as opposed to significantly slower things (the Earth)?
This would be a fun fact to know, but I'm not sure of the formula to figure it out, nor am I certain that something without mass would experience time dilation.
Also, as the sun is a constant source of light, does that mean for every second of sunlight we receive there are also X additional seconds of overlapping "time-traveled" sunlight layering up and bombarding us?
Would the sunlight somehow be less layered and intense if we were closer and it had less distance to travel?

Kinda supports that light isn't the only thing that travels fast as light.
I know that a shadow is the depletion of light, but can a shadow be cast as fast as light?

First off, I thought we were about 4 light minutes from the Sun.
But, I could be wrong.
Given the rate of the orbital trajectory of the Earth around the Sun, and the time it takes for light to reach that point that the Earth is, ....
We have a time differential.
But, it's not 'Time Dilation" which is a change in the perception of time.
It's a mechanical issue of when do we receive the information(light) from the Sun.
Time dilation is a concept of matter's velocity in relation to gravitational fields.
All issues of Cosmological time is strictly mechanical.
It's how much change in matter's relation to itself per unit of instance.
Not a distortion of time itself.
The mechanics of matter forms can be slowed in the presence of strong gravity fields, but that does not change or affect the overall progress of time for this Cosmos, or the Universe.

You are.
It takes 8.3 minutes for light to propagate from the Sun to Earth (a distance of 93,000,000 miles).

Bad♥News:

Approximately 8.3 minutes.
But if you could be traveling at very close to the speed of light, and you left (or passed by) the Sun when the light leaves it, then practically no time at all would transpire onboard your ship by the time you passed Earth!
The flip side of this is that, from the perspective of your ship's rest frame, the Earth would be very close, out in front of you, when you pass the Sun.
Hence it takes practically no time at all, from the perspective of your ship's rest frame, for Earth to fly by!
The time dilation of muons (mu mesons) has been observed in cosmic rays, as they plow into the Earth at near light speeds.
Their half lives are considerably longer when they are traveling, relative to our earth-bound labs, at near light speeds.

Anything with zero mass can travel at the speed of light, not just light (gravitation waves also travel at the speed of light).

How fast does it get dark when you turn out the light?

Light or electromagnetic wavelength will normally propagation away from the point of origin in the vacuum of space at c 299,792,458.00 m/s (the speed of light) .
The same speed a shadow will appear or disappear, or become dark when you turn off the lights.
There is no time dilation effect
“Time dilation is the effect that a moving clock runs slower than an identical stationary clock”, but there is no stationary point in the Universe .
This assumption also leads to not only the clock run slower, the chemical and biological processes slow down.
Therefore, a person moving in the time frame with the clock would detected or see no change in time interval.”
The time dilation effect is a perception.

Yes, if the time dilation effect exist then it is a matter of an effect on the mass of a clock and not time.

How can you explain that light speed is the same for all observers then?
For all that has been said, no offense, both you and Stowell seem to over look the fundamental bases of which "time dilation" is drawn.
For either your assertions to be meaningful, you need to explain the light speed phenomena.
Or don't, whatever, but you are overlooking the critical point.
There is no absolute time.

Ok, then you seem to believe that an observer can superceed the effects of mechanical distortion.
I guess that in your mind, the data you receive form any test of temporal distortion does not affect you.
WOW, SPECIAL!

I don't understand your statement(s).

The relationship of the speed of light is relative to the fabric of space.
It's velocity is so maximal that observation at any speed near it's velocity changes the mechanics of the observer, not the observed.

Time Dilation
The observation of the clock at rest (frame of reference), a light pulse between two mirrors A and B is L <m>, thus the equation.
t = 2 L/c , relative to the frame of reference of the clock at rest .
The assumption of “time dilation” is that the frame of reference of a moving observation traveling at the speed v , at a 90 degrees angel to the two mirrors A and B.
The light pulse would traces out a longer, angled path (½ D + ½ D) between two mirrors A and B, L , is now assumed to be the longer 2D, giving the equation.
t = 2D/c
But the frame of reference between mirrors A and B, distance L for the light pulse has not changed, with the velocity v of the clock .
It is the same distance or frame of reference (L) between mirrors A and B, even with the velocity of the clock .
Therefore, the speed of light (c) must change, and that would violate the principles of relativity.
Light traveling in a straight line with no obstructions.
The speed of light pulse from A to B, therefore can not change.
So if the frame of reference between mirrors A and B, or L at velocity v has not changed, and the speed of light pulse can not change relative to a state or frame of reference of the clock.
Then the assumption of “time dilation”, or t = 2D/c would be incorrect.
The equation should remain at t = 2 L/c , relative to the frame of reference (the clock), even if the clock is moving in any direction to mirrors A and B, comply with the principles of relativity.
