There's better time travel with mathematics and we could say the time has come but it was here already, wasn't it. (Science Daily: Using math to investigate possibility of time travel)

After some serious number crunching, a UBC researcher has come up with a mathematical model for a viable time machine.
Ben Tippett, a mathematics and physics instructor at UBC's Okanagan campus, recently published a study about the feasibility of time travel. Tippett, whose field of expertise is Einstein's theory of general relativity, studies black holes and science fiction when he's not teaching. Using math and physics, he has created a formula that describes a method for time travel.

His book is a perfect example of time travel since it's impossible to write a book before you read it, even when that only happens in your head.
The division of space into three dimensions, with time in a separate dimension by itself, is incorrect, says Tippett. The four dimensions should be imagined simultaneously, where different directions are connected, as a space-time continuum. Using Einstein's theory, Tippett says that the curvature of space-time accounts for the curved orbits of the planets.
In "flat" -- or uncurved -- space-time, planets and stars would move in straight lines. In the vicinity of a massive star, space-time geometry becomes curved and the straight trajectories of nearby planets will follow the curvature and bend around star.
"The time direction of the space-time surface also shows curvature. There is evidence showing the closer to a black hole we get, time moves slower," says Tippett. "My model of a time machine uses the curved space-time -- to bend time into a circle for the passengers, not in a straight line. That circle takes us back in time."
While it is possible to describe this type of time travel using a mathematical equation, Tippett doubts that anyone will ever build a machine to make it work.

How wimpy! Get some investment capital and build it yourself, Mac. With a line of bullshit as we have just read, you could be President if you like. Here's the beauty part with the borrowed money: since you will now have a time machine, you will never have to pay it off. It works the same way as America's national debt since the ones who ran it up are always gone when the bill arrives.
For his research, Tippett created a mathematical model of a Traversable Acausal Retrograde Domain in Space-time (TARDIS). He describes it as a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path. The bubble moves through space-time at speeds greater than the speed of light at times, allowing it to move backward in time.
"Studying space-time is both fascinating and problematic. And it's also a fun way to use math and physics," says Tippett. "Experts in my field have been exploring the possibility of mathematical time machines since 1949. And my research presents a new method for doing it."
Tippett's research was recently published in the IOPscience Journal Classical and Quantum Gravity.

Ed: what if it works?
What do I care if it works? Should I go back to the 60s at sixty-six and hang out with the groovy people. That would be outasight wouldn't it.
Ed: yah, yah, really heavy, man
Critic: Robert Heinlein wrote about going back in time and having sex with his mother
Oh, yeah, that's great. It wasn't twisted enough with schoolteachers fucking children; now it's got to be incest. Get the fuck out!
