Physicist Says Time Travel Is Not Only Possible, but Likely Wednesday, April 02, 2008
Time travel? Teleportation? No problem, says renowned physicist Michio Kaku.
Kaku, a professor at the City University of New York, is creating quite a stir in Britain with the release of his new book, "The Physics of the Impossible."
On this side of the pond, outlandish claims in books are recognized as, well, a good way to sell books.
But in Blighty, Kaku's being treated as if he's Doctor Who informing dim-witted humans about the wonders of the Universe, with front-page treatment Wednesday in both the Daily Telegraph and the Guardian. Even the normally staid Economist is chiming in.
Kaku, one of the earliest proponents of string theory, still a contentious issue among physicists, divides the most common science-fiction tropes, or "impossibilities," into three categories — possible soon, possible in the far future and really, truly impossible.
Category 1, as he dubs it, includes things that may become true within the next century, if not the next few decades: teleportation (already possible, but only among subatomic particles); telepathy (thanks to brain implants); invisibility (already being researched using light-bending 'metamaterials'); laser guns (existing, but hugely power-hungry); force fields; and the discovery of extraterrestrial life.
Category 2 includes things that are theoretically possible but would be realized only with thousands more years of technological progress: time travel (possibly through "wormholes" in space); traveling faster than light; and the discovery of parallel universes.

Paging John Titor.
Hey. He already said that tomorrow.
It seems that teleportation is theoretically possible. We are all made of atoms, and if you had enough technological prowess, you should be able to characterize the current makeup of every cell, and the current electrochemical and biologic state, and then recreate it. Sure, it’s impossible to actually do, but not impossible.
Time travel in a meaningful sense seems impossible. If for no other reason than the fact that if you travel into the future instantaneously, the spot you were at when you started will have moved in the universe in a manner consistant with gravitational and inertial forces in effect at your moment of dissappearance, while you, traveling instantaneously, will not have had any “time” to have those forces applied.
So you should end up in the middle of nowhere. And the energy it would take to make you instantaneously move to the location your position moved to in the real world would be infinite, acting as it would in that instantaneous moment.
One physicists! That’s a consensus, settled science. Get on board you flat earthers, or we’ll come back to your time and kick your butts.
I hate to break the news to the highly paid scientist. There is no “time travel”. He is wasting his and our time talking about it.
I read this next month.
But it only goes in one direction!
And there are no alternate universes.
When he contracts or expands the universe he’ll be sure to let us know.
Time travel “was” developed in the future.
The only reason we have not heard from those “future” time travelers is because, some future intergalactic congress forbid them from coming to the past and fixing (or ruining) their future.
Evidence?
I travel through time every day. It’s always forward at an apparently fixed rate.
Now, if he were a Chemist, it would simply mean he was abusing his own organic synthesis products in order to write things like that. Hoffman and LSD comes to mind.
When did he say this?
Same here except the travel seems to slow between 4:00 and 5:00 pm.
Over all it seems to be speeding up as I get older though.
Me too. It took me five minutes to get here from five minutes ago.
I’ll let him go first.
Not so. The dems will just pass a law mandating perpetual motion and raise taxes to pay for it. Voila'.
I met a guy in Los Angeles back in 1997. He told me about some people who were time travelers. They were coming back to play stock market games. This guy was named John Titus or something like that. He also claimed to have made a fortune investing Microsoft in the early 1990s. Told me to ‘Beware of Bubbles.’ But he never told me who ‘Bubbles’ was . . .
Great Scott! Whatever you do, don't go back and tamper with the primaries! It could change the future forever.
Bump
note to self...look for dimensional phase shifter invisibility cloak I left near girls lockeroom
I always yell out MICHIO!, when he comes on TV. We watch a LOT of Science and Discovery channel, and he’s on ALL the time. ;o) I call him this generation’s Carl Sagan, except that he doesn’t have that annoying condescension to his voice that Carl always had. Michio is very upbeat and likeable.
I disagree. It takes much longer to get through a Monday than it does a three-day weekend.
Sad!
And he calls himself a physicist?
Time travel possible, says boffin
Possible? We all do it every day

The Taliban travel considerably slower than most people and are now some 800 years behind the rest of the world. Other areas travel slightly faster - the Isle of Wight, for example is only 27 years behind the mainland of England, while New York is exactly five hours and fifty years behind.

No time travel? So you’re stuck at 2:58:02 while the rest of us move on into the future? So sad.
I have no idea if time tavel is possible or not. It does seem that if it happened, it would have to create a new universe each time it occurs.
Now we can go back and warn Eve!
...they know no one will believe them. *If* we have had time travelers in the past who were foolish enough to announce themselves I'm sure they enjoyed the lobotomies, electroshock, and Prozac they were subjected to. My estimate is that if it is possible then at the time we "discover" the principal and try it out only then will we get to meet the rest of the people travelling "up" and "down" time.
Which may result in your never existing which means you couldn't go back and warn Eve, and thus, if you didn't warn her the fall happened, so you did exist to go back and warn her which made you not exist....
That's what we call a PairofDucks. They are two little ducks making sure you don't mess with their eggs in the past.
Kaku, is the genius who speaks to you as if your an equal.
He enjoys teaching as much as learning.
He's on my , "if I could have diner with.." , List.
I once read a neat little story in which time 'portals' were opened from a future Earth to many different past 'earths' and each portal caused a 'branch' of our universe to occur. This meant they could pump all the oil from the Middle East in 1850, do it again from 1849, do it again from 1848, and etc. The story was interesting in that it also addressed 'immigration' from the past to the future. The little storyline with Mozart coming to the future and then applying his composing skills to rock music was really interesting.
I don’t believe in time travel because no one has ever done it.
Someone ought to make a movie based on Poul Andersen’s “Time Patrol” stories. I always thought that they were not only fun, but they also explained away a fair number of paradoxes really well.

He was on with Art Bell on the 28th for 3 hours.

I'm not sure I followed your description. However, it's fairly well-established that wormholes would enable time travel. This primarily has to do with the interplay between special and general relativity - remember, there is no such thing as an absolute point in space or time, and in fact the flow of time itself is a relative phenomenon. The caveat is that you cannot travel to a point in time prior to the creation of the wormhole.
The fact that wormholes would enable time travel is one argument, by way of proof-by-contradiction, that wormholes cannot exist.
...Oh god, you're serious, aren't you? :)
Michio Kaku and Art Bell are fairly awesome by themselves, but together they have the best show on the planet.
TPB, the best thing to ever come out of Canada.

Nah. In Star Trek what they did was kill you and put a clone where you were supposed to beam to.
