>could we observe the past directly in some way
Yes. When we see something in deep space, light years away, we're observing that something's past, in real time.
If we look at a star that say, 100 light years away, we're watching that star as it existed 100 years ago. To see what's happening with that star at this moment in time, we'll have to wait 100 years, perhaps longer if that star is moving away from earth.

If time travel were ever possible, it would be possible now.

So we don't have to go 900 year into the future using a stolen Klingon time crystal to get programmable matter?

Reply to The multiverse by Manureofhistory
The multiverse is one of many similar theories who's sole purpose is to hypothesize about unknown. For everything we know about physics, there are still a lot of things that don't add up, and things like multiverse theries just propose possibilities that might fill in the blanks.
