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.

Category 3 consists of things that really are impossible because they violate the laws of physics. Only two concepts qualify: knowing the future and perpetual motion.

Looks like HDRkid and his RV gadget lie in category 3!

Teleportation, time travel and aliens - a vision

i think is fox news thats had the edited version of this not Ray...

compare to:
Type 3 impossibilties

Technologies that violate the known laws of physics. If they turn out to be possible, they would represent a fundamental shift in our understanding of physics: perpetual motion machines, precognition

be the Judge...

Teleportation, time travel and aliens - a vision of tomorrow today

Even the most outlandish science fiction could become fact, says professor

Einstein gave hope to scientists chasing the most outlandish theories when he famously declared: "If at first, the idea is not absurd, then there is no hope for it."

He then proved the existence of black holes and the notion that time passes more slowly the faster you travel.

Now one of the world's most distinguished physicists has scrutinised some of science fiction's other concepts, such as teleportation and forcefields, and is convinced that they too can become reality.

Professor Michio Kaku, of City University in New York, has ruled out time travel for at least a few millennia, but believes invisibility cloaks and telepathy could be possible this century.

"So many times predictions are made that certain things are impossible only to find them becoming possible a decade or a few decades later," he said. In his new book, The Physics of the Impossible, published in the UK today, Kaku rates seemingly impossible phenomena according to how likely they are to happen.

According to who's version of physics?

The problem with the time travel going through the black hole is the first mistake. You do not go through the black hole to time travel -- all of time is present at the event horizon. That is what was brought up by other physicists - make sure you know what it is that what they are really stating. Yes, Space is there also, but because of gravity, time is there also, and although all of Space is not really there, Time may be more there because that is what is really happening when at a black hole.

Parallel Universes have been proved according to other physicists mathematically. That states that now you really should think that there are parallel universes.

No doubt, other physicists are still getting hung-up on string theory or now what it is -- M Theory.

Thoughts leap ahead - that is why, humans can ascertain the trend and come up with what the future will seem to be -- unless the thinking changes. And so far, that has always been another question?

I'm bogz /ttiforum/images/graemlins/smile.gif I wanted a new nick name.

I understand why perpetual motion.... Why doesn't physics allow us to know the future though?
 
s19n (bogz),

Why doesn't physics allow us to know the future though?

As far as I know there isn't any well defined law or laws of physics that forbids knowing the future. In fact we predict the future all the time. For example we can predict to a good approximation the future positions of the major celestial bodies in the solar system.

Of course that's not really what you were refering to. Your reference was to having precise foreknowledge about complex sets of interactions like how individuals will react to their environment and decisions that they will make. Most of the argument involving this sort of situation is based on logic with a good mix of physical law. Such foreknowledge leads to logical paradoxes that aren't easily resolved. If indeed the foreknowledge is "the future" one can always conspire against and successfully avoid that future. That creates the paradox because it apparently wasn't the future after all.
