Based on that principle you could go back but not return to the present because it hasn't happened yet.
I spent the last week in Scotland and, going by Nicola Sturgeon's hairdo, it's still the 50s up there. On that basis, I'd have to say that time travel is possible.
Not at the level of quantum mechanics though, so once we master that its back to the future for everyone
but surely if you had traveled back in time then your future would have already existed so you could go forward to it ? Or is it like you catch the last bus to the past and then theres a strike or a sudden petrol shortage so youre stranded unless you have an HGV license ( well, the equivalent for buses ) or the good fortune to be on a bus that runs on diesel ?
My heads not hurting, as soon as a slight headache began to set in I traveled back in time by a couple of hours , took two paracetamol and returned just in time for this thread going into its second page
It's forward TT that's theoretically possible not back, if you travel near to light speed, not past it. At 90%+ LS the effect vastly increases, eg; if you traveled away from earth and then back, to the earth's new position in the galaxy, for about 10 years you'd come back in around the 2040's Time is not stable in the universe. Planck and then Einstein proved this after the discovery of Photons. Sorry for being a geek!
Yes, Gambol's an idiot, you can only go forward in relative time - and you go forward in time by going towards the speed of light (you don't have to surpass it). Most of the man-made satellites orbiting our planet are moving forward in time, slightly faster than us, due to the speed they are travelling relative to us. So when we fit the likes of clocks and GPS software we have to modify them slightly from Earth settings to counter this move forward in time http://en.wikipedia.org/wiki/Time_dilation I am not sorry for being a Geek.
