In theory if you traveled in a circle fast enough there would be a point when you arrived at the depature point before you left it?

No. Time travel, however you attempt to go about it, cannot happen. If it did, we'd be visted by time travellers from the future.

Travel back in time and travel forward in time, yes. because time zones are different and time is just an idea. uk and the far east has 8 hours time difference, plus 8 hours in the far east. so when you travel from the far east 1pm on 1st of january and arrived in the uk after 6 hours, you will find your watch at 7pm but in fact the time is 11 am 1st of January, which is 2 hours earlier than your departure time of 12 pm. You do the reverse traveling from UK to the fareast to travel forward. I think the real question here is "can we change the events that happened before?", my answer would be NO!

Time is not constant. That's why people take about space-time. You wont be able to travel back in time by doing that (you'd have to travel faster than the speed of light - and that's not possible, E=mc2, says that as you approach the speed of light the more energy you put in to increase your speed, your mass will increase instead - or something like that.) you can slow time down by increasing your speed.
Didn't they do that with the two atomic clocks, sent one up to space spun it round the earth a few hundred time as fast as they could and when they check the two clocks, the one that was up in space had slowed down and was behind the 'static' clock.

No you would have to travel much faster than light, you would not travel back in time however, you would simply get back to where you started before the light reflecting from your body had updated if you like, showing your new position, you would arrive just in time to see your self for less than a nano second then you would disappear, you would not travel back in time, more like time was frozen for the length of your journey

No, because time is forever moving forward for you so you would still arrive after you'd left.
To be perfectly honest I wonder if time is not linear but layered in dimensions so that if we found a different frequency we would be in a different time. I really don't know enough about this though.
Time to go study I feel...

I'll have to disagree with you because time is not a NATURAL feature of our universe. It's nothing more than an abstract concept invented by our species to separate events. In order to accomplish what you describe you'd have to physically travel back in time. That can't be done because there's no such material thing as the past following along behind us. Likewise, you can't move ahead into any physical future since there's no such thing.

the faster you travel the closer the departure and arrival would be, but they could never be the same or overlap as it will always take time for you to travel the circle.
plus the fact that the closer to the speed of light you get the more your mass increases up to infinity....

Your proposition is the perfect method for disappearing up your own *** - if it weren't for the fact that you gain mass when attempting to go faster than the speed of light, rather than going faster. So, conventionally speaking, one cannot achieve your result because you'd die in the attempt - albeit it would be fun trying. Let me know if you end up with a smelly head, though.

Yes it is possible I have just done it!
I answered this question before I read it and got best answer before you asked it but nobody voted for me because they didn't know the question so I failed to get 10 points and went back to level 1 before I joined Yahoo answers
If time is relative would it be an Uncle or an Auntie type relative?
Does this answer your query? :-)

There could be a possibility "IF" we were to travel that fast - However it requires infinite amount of energy to do so which is impossible by present technology.
