As you can tell, I think in todays life, it is impossible. But I want to know what YOU think.

Oh, I always forget about them! But the amount of power that would be required to do it would be quite noticeable.

to quote myself from this spam-thread:
| Quote: | But, we are actually already on a time-machine!
1. We ar all on the surface of a gigantic-mass,
which makes our time to progress faster relative to the time progressing in an empty part of the universe.
2. We are all moving quite fast (as planet, as solarsytem and as galaxy) which also makes our time to progress faster relative to the time progressing for someone who is not moving (that fast).
Welcome to the relativistic universe!
Even the creation of an time-machine by man is possible.
But only with direction future and a quite low speed combined with very high cost. |

There are multiple sides to this issue, including the metaphysical and the theoretical scientific aspects.
On the theoretical scientific side, relative time travel (in either direction) is plausible with the caveat of certain, specific, not-yet-available technology ( wormhole manipulation and C-scale transportation )
On the metaphysical side, there is the issue of causality. Specifically the question are past events changable? and if so, how does the universe (as we know it) accommodate those changes? And if not, what would the universe consider an 'event'? And then would any interaction with past events be possible?
A number of authors have written some interesting books (with a wide range of scientific influence) regarding the topic of time travel. Isaac Asimov (my hero, btw) wrote The End of Eternity, which explains some possible benefits, abuses and mechanisms associated with time travel. It's a good read, too.
The Orson Wells book is one of the few sci-fi books that I think was better as a movie 
btw: the relative forces on local time are definitely real and measurable. Even cesium clocks on satellites in non-geosync orbits lose entire milliseconds every year!

We are already travelling though time. How quickly depends where we are in the universe. Here on Earth it's taken me a few seconds to write this very message!
