A little more on the topic of time travel. We all travel in time, forward, the problem is that there is little we can do to stop or change direction.
It's like time is a boat on a river and we don't have any oars or motor.
We know from Einstein that time is not uniform throughout the Universe and that Gravity and Velocity, affect our relative time. So, time passes
slightly differently here on the Earth, than it does on Pluto for instance. The reason is that the Earth is closer to the Sun, than Pluto and so the
Earth is under more of the Gravitational influence of the Sun. The difference is very slight but it is real. The closer you are to a large Gravity
field the more slowly time travels, as seen from an observer that is not under the Gravity influence.
What this means is that you could make time slow down for yourself if you could move close to a Black Hole, or other very large Gravity field. Or time
would move more quickly if you could move farther away from a large field.
Put this all together and we know how to move forward in time, and alter the relative passage of time. What we don't have, is a local Black Hole that
we can get to.
We could also move forward in time by using suspended animation. If we could slow down the bodies processes, then we could sleep through years,
decades, centuries. When we were revived, it would be like we jumped forward in time.
I actually experienced something like this. Many years ago, I worked offshore for a diving company. We went off on one job late in the season. We were
on a small work boat, on large swells. On this trip, I got dehydrated, and then I got seasick. I was as sick as I have ever been for 5 days. The seas
got so bad that we cut the job short.
So, I went home, it was a Saturday night. I got home late around 2am, and let myself into the house and went to bed.
I woke up around 7 am and my wife was up and getting dressed. I asked her, what she was doing? She said, "I'm getting ready for work." "On
Sunday?" I asked. She looked at me and said, "It's Tuesday." I had been asleep continuously for 3 days. It was as if I had jumped forward in time
by 3 days. At first I was incredulous, "It can't be Tuesday, I just went to bed." Then I looked at the clock, turned on the TV and checked the
news. Sure enough, it was Tuesday.
This is a minor example, but it is what suspended animation is supposed to be like.
