Nope. 300 million seems like a lot until you realize billions, trillions, quadrillions, octodecillions are nothing compared to the probability of a collision. I'll have to find my post referencing it, but I wrote a paper on electron/atom phasing. Theres a really old story about shaolin monks being able to phase through solid objects, with their proof being a man who was found part way through a wall, with no damage to the wall and various other structural engineering things that I don't care about that show that he wasn't built into the wall. Without getting too deep into the theory of it, the electrons in your atoms have a chance of passing through those of another substance if they hit together at the same resonant frequency, causing the atoms to effectively "teleport" through material. There are a few octillion atoms in a human body (1x10^27). Again, I'd have to find all of the math again to actually prove it to you, so take this as anecdotal evidence until I do, but my conclusion was that if 7 billion people on earth walked into walls non stop for 76 years without break, with a 1 second interval between bumping into the wall and trying again, there was something like a 0.75% chance that someone would walk through a wall.

That is a far greater chance of happening than finding a collision. People always post that infographic talking about converting the solar system into energy and creating a perfect quantum computer. I'm saying you have a much higher chance of walking through a wall than colliding. Is it impossible? Well, I suppose not, there was that monk that was inexplicably found in a wall. But the chance is so low, its not worth wasting your time on.

*edit* Google has a DWave Quantum computer that you can rent for $10-20k/hour of compute time. I wouldn't be surprised if someone has already tried to use it to find a collision.
