First part: Light (photon) is a form of energy, right?
Second part:Theory of relativity says that our experience of Time is relative (dependant of the facts like: are we moving or not).I don't agree with that.
Third part:- Since it takes some time for light to reach us - it means that we don't see object in their "now" time, but in ours "now" time.
Addendum:- If space is expanding at the speed of light that means that at the furthermost part of universe one could see the big bang.
And if we ever get to travel at speed larger than speed of light - we could see the universe (and ourselves) in it's past. Please note (we can't interact with our past, just see it.)
