I just finished watching a show on the Science Channel about Stephen
Hawking and the question of information being lost in a black hole.
The next show is on time travel and whether or not time travel is
possible. I saw a show like this one before. It might even be the
same one. Well, it got me thinking just now about time. I think I
finally figured out what time is. A moment in time is a specific
configuration of the universe!! So if you want to go "back to" a
certain moment in time, you can do so by changing the configuration of
the universe to what it was at that moment in time. For example, to
bring people back to life, you'd have to reconstruct their exact
bodies with their DNA sequences etc using the basic elements. Does
this make sense in theory? It's like System Restore on a Windows
machine - but you'd have to change the entire universe if you wanted
to really go back to a certain moment in time. I guess, you could
just change the local universe and be happy with the results. So yes,
time travel is possible!!

Did you find out the information is not lost?

So lets say you invent a machine to do that. It would also have to unbuild
itself as well.
