The first description of a quantum entropy feedback amplifier-actuator (patent pending):
It might be possible to manipulate the normal laws of probability.
According to the Many Worlds interpretation of quantum physics, our timestream keeps splitting into multitudes of possible outcomes. Every possible subatomic quantum event, no matter how small, causes a new universe to 'pop' into existence, complete with memories of its own past. In a small fraction of new universes, everything will have 'gone right' by pure chance, meaning any unlikely but not impossible desired outcome will have come to pass somewhere. The near-miracle that we wanted to happen actually did happen there. A handful of coins always comes up heads. Moving randomly, atoms just happen to rearrange themselves into any desired object.
It might be possible to amplify these extremely rare possibilities, so they would outnumber all other undesirable timestreams.
This would violate the laws of entropy as we know them. It might be necessary to first increase entropy levels elsewhere, perhaps inside stars or empty space, or by slightly speeding up the expansion of the universe.
How it would work:
Observers in many universes would experience many random outcomes.
The most successful ones would then take steps to 'multiply' the universe they inhabit. The less successful observers would do nothing, or try again until they were successful.
A selected universe could be multiplied by rapidly increasing its number of possible future states. This could be done by 'releasing' the disorder in a formerly highly symmetrical system; for example by unleashing a large amount of energy in a chaotic way.
One way to test if such a device is possible would be to detonate a large number of nuclear devices (as big as possible), each controlled by a random ten-second timer.
After a large number of detonations, timing deviations might become noticeable. On average, most detonations might occur slightly earlier than expected during the ten second interval.
If it works, it would tell us something about our multiverse, and about reality as a whole.
According to most standard theories, this method would never work, but then the experiment has never been conducted.
For example, there might always be an 'opposite' possible universe to counter every probability we try to amplify.
Perverse paths:
This feedback process would have hidden dangers. Even if an outcome looks perfect, it would still be fundamentally random.
Even after a thorough inspection, there would be an overwhelming probability that as many hidden faults as possible remain in the seemingly desired outcome.
The moment the feedback process stops, the contrived situation might fail at the earliest possible moment.
