I know the textbooks say light travels 186,282.4 mps, but if time slows for a very fast object, how do scientists really know the speed of a photon?
Please explain this to me Drakkith. I'm only 12 years old.
Is it because time dillation only affects objects with mass, and photons do not?
No, you misunderstand time dilation. Time dilation is an artifact of remote measurement.
YOU, for example, right now, this very minute as you read this, are traveling at .9999c from some frame of reference, and observation from that frame of reference shows you to be seriously time dilated. Do you feel any different, knowing that? You shouldn't, since you are NOT time dilated from your own frame of reference.
I require more clarification. If I am not actually moving at 99% of c, is it because the frame of reference is moving at 99% of c? If so, would the frame of reference would see me as moving slower than c?

If light is not affected by time dilation, are there any "light clocks" to measure time exactly without the effects of time dilation? Or am I still getting the concept wrong?

Also, I changed my mind. I will only post questions.

I think you are still getting the concept wrong. I say again, time dilation is an artifact of remote observation. You in your own reference frame cannot measure any time dilation on you because there IS none, and you cannot help but measure time dilation in a different reference frame that is moving at relativistic speeds relative to you.
You can COMPUTE the "local" time scale of a different reference frame that you see as time dilated, if you know its velocity relative to you.
Can you expand on that? Not sure it what sense you mean it is an "artifact of remote observation".
It sounds like you are saying it's an illusion of sorts, or has no physical meanings / consequence.
