The Home Parallel Universe Test 754
Sam Sachdev writes "David Deutsch, a physcicist at Oxford, has designed a home test for parallel universes. Using a pin, a red laser pointer, a piece of paper, and a relatively dark room, he claims that the results from this experiment confirm the existence of parallel universes." Okay, so it may not really be proof of parallel universes, but it's a fun trick to try with a laser pointer nonetheless.

Well, how do you know if you live in such a "multiverse"? The answer was proposed by Max Tegmark just a few years back:
Take a gun, put it to your head, and pull the trigger. Repeat several times. If the multiverse model is correct, then your "self" will continue to exist only in those universes where the gun does not fire. So if you try and pull it a bunch of times and nothing happens, you must be one of the many parallel yous who happens to live in a universe where, in spite of probability, the gun did not fire.
Of course, I would not recommend trying it. If the MWI is correct, well, then in another universe you already have tried.

You fire a couple hundred billion volkswagons out of a *very* high speed cannon at a target a couple million miles away. In the middle of this target is a couple of slits just about the width of three volkswagons.
A couple million miles on the other side of that target, you have this larger target; we'll call it the "screen" for convenience. Now, because some of those volkswagons don't impact the slit directly, you have a "spray" of volkswagons erupting from those slits - they don't just stream thru nice and orderly, some get tangential velocities from "interfering" with one another, and with the borders of the slits.
If you map the patterns of the volkswagon impacts onto the "screen" you'll notice that they have a mathematical distribution. We call this distribution an "interference pattern". This pattern has a distinctive distribution; let's call it the "volkswagon" distribution.
So after repeated experiments, you determine that the volkswagon impacts have a certain mathematical distribution; but also you find that there is a small amount of randomness to that distribution. We'll call that randomness "quantum volkswagon mechanics" - thinking that perhaps there is some small variation in the mass, velocities, and impact geometry of each volkswagon that we can't quite qualify in our experiment. After enough experiments, we determine that our error levels are follow a distribution that has some mathematical relations to the size, mass, and average spin distrubtion of the volkswagons we fired. There may or may not be an additional statistcal factor relating to our observations, which we will call Force "X".
On down the line, we find that some of those volkswagon may shed pieces of themselves, which may or may not contribute to Force "X".
Over years of experimentation, we qualify some of those pieces, and their effects, but we know that we can't adequately predict nor determine the quantity nor various qualitative aspects of those pieces. So we develop more theories, and essentially, that's where we are at now. We suspect that there is a relation between the Q&Q+Unknown of those pieces, the volkswagons, the slits, and the fact that to detect those pieces, we have to employ smaller and smaller BBs to bounce off of them, but the more we observe, the more complex it gets.
Meanwhile we do have some math to describe the whole thing - it's called wave mechanics - but frustratingly, we can't seem to relate that math to simple things like the Apple falling on Newtons' head.
This results in thousands of journal articles by the more learned members of our society; and ultimately, after being filtered thru many learned and not-so-learned members of our society, results in a description on a information site called slashdot, in which the members debate it, including speculations on supernatural dieties, callings upon fantasm including time travel, and eruditions meant to inspire humorous responses.
