Yeah, I realized after I posted the link that it didn't really get into the findings much, hah. Basically, a group of scientists were studying the behavior of photons. They shot photons in a box through a flat surface with two slits to see what would happen on the other side. The first trial that they attempted was really shocking for them because they expected the photons to act like solid objects and simply go through the two slits and end up as solid lines on the other side mimicking the slits. Instead, they produced a diffusion pattern, like water ripples. On the other side of the slitted surface, the photons produced a single line in the center of the two slits and then the ripple effect, which faded as the photons grew further from the center. This indicated that they produced every possible outcome. Baffled by this, the scientists put a photon capturing device (like a camera for photons) into this box to more closely observe the photon behavior and see why they made the diffusion pattern. When observed in the second attempt, the photons behaved like the scientists expected them to in the first place and made two neat lines where the slits were. This proves that cognitive thought and active observation has an effect on our surroundings.
The theory gets a bit more complex after that and goes into some really abstract ideas, similar to the old saying, "if a tree falls in a forest and no one is around to hear it, does it make a sound?"
