Time travellers could use parallel dimensions to visit the past, scientists claimWe, of course, don't observe any of that. None of that. Zero. No universes spawning from quantum measurements (that would make quite a mess, wouldn't it). Nor do we observe actual time-travelers hopping out of other universes - contra Arnold.
Physicists reveal sensational findings which could allow science fiction dreams to become reality
THERE are multiple timelines playing out in parallel universes, according to a team of researchers.
The sensational claim was made by a team of physicists, who believe that the parallel universes can all affect one another.
The team’s ‘Many Interacting Worlds Theory’ provides a whole new perspective on the ideas underpinning quantum theory, a notoriously complex strand of physics.
Professor Wiseman said: “The idea of parallel universes in quantum mechanics has been around since 1957.
“In the well-known ‘Many-Worlds Interpretation’, each universe branches into a bunch of new universes every time a quantum measurement is made.
“All possibilities are therefore realised – in some universes the dinosaur-killing asteroid missed Earth. In others, Australia was colonised by the Portuguese.
“But critics question the reality of these other universes, since they do not influence our universe at all.
“On this score, our ‘Many Interacting Worlds’ approach is completely different, as its name implies.”
The entire concept is built on a large stack of presuppositions that start with the fatally flawed Copenhagen Understanding[*] of Quantum Mechanics. That plus String Theory, which is merely mathematical fantasy, with obvious and logical mathematical intransigence such as claiming that infinity divided by infinity = 1.
It's shameful that physics has been reduced to this sort of absurdity. Make that cumulative absurdities. The original requirement for experimental proof of a deduced theory based on inductive observation no longer hampers the pursuit of "physics"... to its huge intellectual detriment. Objective knowledge has been replaced with Appeal to Authority, where the designation, "scientist", is given the authority of the modern cult's priesthood.
Hopping onto a parallel universe contained in parallel dimensions in order to go backward in time is actually merely poor science-fiction.
* When viewed through Quantum Field Theory, the absurdities generated by the Copenhagen Understanding go away. Schrodinger's Cat is still alive .
