In The Daily Mail, Stephen Hawking writes that time travel may be possible. Since time and space are "wrinkled", people might use these wrinkles as shortcuts in time:

Nothing is flat or solid. If you look closely enough at anything you'll find holes and wrinkles in it. It's a basic physical principle, and it even applies to time. Even something as smooth as a pool ball has tiny crevices, wrinkles and voids. Now it's easy to show that this is true in the first three dimensions. But trust me, it's also true of the fourth dimension. There are tiny crevices, wrinkles and voids in time. Down at the smallest of scales, smaller even than molecules, smaller than atoms, we get to a place called the quantum foam. This is where wormholes exist. Tiny tunnels or shortcuts through space and time constantly form, disappear, and reform within this quantum world. And they actually link two separate places and two different times. [...]
Given enough power and advanced technology, perhaps a giant wormhole could even be constructed in space. I'm not saying it can be done, but if it could be, it would be a truly remarkable device. One end could be here near Earth, and the other far, far away, near some distant planet.
Theoretically, a time tunnel or wormhole could do even more than take us to other planets. If both ends were in the same place, and separated by time instead of distance, a ship could fly in and come out still near Earth, but in the distant past. Maybe dinosaurs would witness the ship coming in for a landing.

Also, everything happens at once, time is just how we perceive it.
The theory could be correct. That doesn't mean the execution is physically possible.
Actually, I agree with Christophe. Why haven't people from the future traveled back to visit us? Are we so boring we are not even a tourist destination? Wouldn't somebody have gone back and killed Hitler? The only logical conclusion, unfortunately, is that we do not exist in the future. Or more specifically, we do not exist long enough to perfect time travel.
Greetings from the year 3000....
[insert less lame joke here, and pretend I made it up]

I concur with Cristophe.
@Pony...we didn't need a telephone-like apparatus on the moon to travel from the Earth to the moon. Because we can move about in these three dimensions we know so well. Therefore, expanding these other dimensions should give us additional capabilities to move about without the need for a telephone booth on either end of the journey.
In conclusion, regardless of which timeline we travel, I don't believe there will ever be a dead, male Northern Quoll without a smile on its face.
Draw your own conclusions.
Okay, so I'm not a scientist, but my logic makes sense
he stated that time travel to the past is not possible due to "feedback" that closes the wormholes.
Time travel to the future is possible, but if u read the article, you know that type of time travel is not the hollywood-type. It merely means time for the "travellers on a high speed vessel" is slower than the rest, hence they aged slower.
read before u comment, pple!
We may not be able to make the time tunnel, but it could be possible.
