Professor Bubbleworks unifies dark matter and alternate realities
The end of the Professor Bubbleworks ride at Chessington (don't ask me why I was there - I am a kid at heart) has streams of water arcs that pass above your head. Those arcs are periodically lit by strobe lighting, effectively freezing and focussing your attention on a particular water drop's trajectory.
This got me thinking about time and alternative realities. There is a common thought that all possibilities are playing out all of the time (let's conveniently ignore what that might mean for conservation of energy and the bounded/unbounded universe); but why do we only experience a single reality (i.e. why haven't I won the lottery yet?). Could it be that each reality is like one of those water droplets, but the collapsing of the wave function (I can't remember what that actually means ;-) ) is like the strobe or a filter on our reality? If that was the case, could we alter the filter or frequency of the "reality strobe" to "light up" alternate realities?
What's this got to do with dark matter? Well, there's an awful lot of it... and we don't know what it is and we can't "light it up" to look at it... but could the dark matter actually be our alternate realities playing out?!
