Many theories state that the closer to the speed of light that you travel, the more time will dilate. Which means say an object is traveling at 0.8 of the speed of light, time for that object will pass by the same. However, time for everything outside of that object and speed passes by much faster in comparison. This is all based on theories of course. But my assumption from this is: it's possibly that traveling at the speed of light, time has not moved for you, but for the rest of the universe it has. So what this could mean is it takes light time to travel based on our observation of it. However, for that light particle, perhaps no time at all has passed for it. Thus showing us what is happening right now from wherever that particle came from. It's a bit hard to put into words, IDK if i came out clear as to what I was trying to portray here or not.
I fully get what you are saying. The light, likely does travel great distances in <pun> no time at all </pun> ha ha... I'm not funny, I know....
Time dilation makes $#it SUPER complicated.
Still though, you are mistaking 'now' with 'now right here'. If light bounces off an apple, and flies off into space, that light won't percieve any length of time, but the wavelength of that light will remain fixed to what it was when it left the apple's surface. So that years later, for the apple, and lightyears later for the light, as it will be happily floating along percieving 'no time' only distance, will still have the same wavelength as was caused by the apple as it was. So that at its destination, where some other being percieves that light, it will see the shiny red apple. The apple though, will have aged and rotted away. Once the apple and the light part physically, they have no way to interact with each other. The rotting apple can no longer affect the wavelength of the light that has already left.
Light from point A to point B, B sees what is 'now' in A's past. That 'now' being the 'now' for the apple/ point A. That's easy.
Time dilation can be used to move 'forward in time', by moving an object with mass, like a person who would percieve the trip (which that gets all sorts of whacky).
If I left point A at 99% the speed of light, and came to rest at point B, and turned around, I would still not be able to see the 'past'. I would have traveled a great distance, that for me maybe was only a few seconds. But what happens back at point A is they would not see me arive for another few mins/hours/years depending on how far I went. Thats some trippy stuff right there...
