What could be the world's largest quantum physics experiment is happening today, 30 November 2016, and researchers need people from all over the world to get involved by helping them test the laws of quantum mechanics.
The experiment, run by 12 different labs around the world, will test Albert Einstein's idea of local realism - one of the fundamental principles of quantum mechanics. All you have to do to help out is play a bunch of online games for science.
So, what will all your gaming efforts achieve? Basically, local realism is an attempt to overcome what Einstein referred to as "spooky action at a distance".
In quantum mechanics, there are two things to keep in mind. First, particles don't have a distinct value until they're measured. And secondly, when two particles are entangled, one of them will immediately affect its entangled partner, no matter how physically far apart they are.
Einstein didn't like that, because, in theory, it seems to violate the speed of light - hence the "spooky action" quote.
So he came up with the idea of local realism, which assumes that a particle must objectively have a pre-existing value for any possible measurement - and that way, information doesn't actually travel between two entangled particles faster than the speed of light.
Since then, researchers have come up with a test to measure whether or not information is actually travelling between entangled particles, known as the Bell inequality test.
And if it's violated in actual experiments, it implies that quantum mechanics violates either locality or realism, and the idea of local realism (and Einstein's hypothesis) therefore cannot be correct.
Several experiments over the past few years have reportedly violated Bell's inequality - last year, the first Bell's inequality experiment was completed without loopholes, but there's still dispute over whether or not local realism actually holds up.
The new worldwide experiment aims to settle the matter once and for all, by using a huge amount of random, user-generated data to test Bell's inequality.

Games. What a terribly boring way to do science.

Randomly hitting 1's and 0's is pretty damn hard.

I still can't get past the last stage!
