Parallel universe proof boosts time travel hopes

Parallel universes really do exist, according to a mathematical discovery by Oxford scientists that sweeps away one of the key objections to the mind boggling and controversial idea.

The work has wider implications since the idea of parallel universes sidesteps one of the key problems with time travel. Every since it was given serious lab cred in 1949 by the great logician Kurt Godel, many eminent physicists have argued against time travel because it undermines ideas of cause and effect to create paradoxes: a time traveller could go back to kill his grandfather so that he is never born in the first place.

But the existence of parallel worlds offers a way around these troublesome paradoxes, according to David Deutsch of Oxford University, a highly respected proponent of quantum theory, the deeply mathematical, successful and baffling theory of the atomic world.

He argues that time travel shifts between different branches of reality, basing his claim on parallel universes, the so-called “many-worlds” formulation of quantum theory.

The new work bolsters his claim that quantum theory does not forbid time travel. “It does sidestep it. You go into another universe,” he said yesterday, though he admits that there is still a way to go to find schemes to manipulate space and time in a way that makes time hops possible.

If one believes the Internet legend/myth of John Titor, a visitor from 2036, the device that was inside the “trunk” of the Corvette he drove utilized a “micro-singularity”, which used Einstein’s Theory of General Relativity of Gravitation to bend space-time.

Also quantum tunnelling is another possible method.

As I have noted in previous posts and other writers have mentioned in published journels, if one is able to travel into the past, it’s not really the traveller’s world-line they’re going to, it’s one that closely matches their own. As mentioned in the article, this cancels out the Grand-parent Paradox.

Alot of physicists still dispute the “multi-verse” theory. As mathematical evidence keeps mounting, one can’t keep denying the evidence.

Maybe that’s why the neocons claim they can manufacture reality?

Nah.
