So, in 1 years time if you are 1 light year away from where you are now and looked through a telescope to your exact position you would see what you are doing now, even though it's 1 year later, so you are looking back in time (sorry if that's hard to follow I've already spent about 10 minutes trying to explain it the best I can!)
Whilst I don't believe you can go back / forward to a period in time you can actually see different time periods to the one you're in (IE the state of the sun if you look at it)

As I said, what a bizarre universe you live in.

That's exactly what I'm suggesting :)
I'm sure it is possible, just as what's been said, it won't be accessible in our lifetimes. But that's the joy of my interest - stuff that doesn't seem possible has been witnessed, so therefore must be possible... Just with this particular topic, physics seems to be able to back me up!

What a bizarre universe you live in.
