Physicist Says Time Travel Is Not Only Possible, but Likely

www.foxnews.com...

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.

Well its about time. I've been waiting for something like this. I knew teleportation is possible. Is it, however, possible to concentrate the teleportation into time so that you can teleport basically from time to time? I believe time travel requires some form of teleportation to work.

Somebody has already done teleportation with small molecules and using lasers to slow down electrons with cooling. Can't remember the guy's name.

The real issue is the paradox whether the same object can exist in two places at once.

If you can teleport from place to another then it also follows that you should be equally able to teleport from one time to another.

It actually seems to challenge string theory rather than corroborate it ?

A Kiwi guy called Peter Lynds has created a stir by challenging some accepted thinking about time. Pete advocates this about Quantisized time:

…time itself is continuous, not an infinite series of discrete steps. Units like seconds, minutes, and hours are just a convenient fiction…they don’t represent anything objectively real in the world.
