In the classic experiment, particles sent through a single slit behave as if they've been sent through a single slit, while even if sent one at a time in a direction with two slits, they display an interference pattern after enough have been sent to make a pattern show up.
That still dosn't explain really how each individual particle KNOWS it has a choice of two slits... right?
How is this mathmatical change distributed through the path of the experiment? It must happen instantly, therefore the effect travels faster than light - but no force can travel faster than light - as it needs carriers of that force to interact with.
What if the very act of creating an extra choice in the path of/for the particle makes some kind of inherent "pattern" within the fabric space/time for the particle to travel through?
This "pattern" is what directs the particle to exhibit it's wave-like properties or interference. No force involved, just math.

"Spooky" action resulting from quantum entanglement does occur faster than light, however it cannot be used to send information. (or rather, it can, but it will always require something else travelling at the speed of light or slower) However, fire two entangled photons in opposite directions, and have a double slit for one to pass through a kilometer, an AU, a light year, or a parsec away... if you try to garner 'which path' information from the entangled photon, it will destroy the interference pattern for the other photon instantaneously. Such behavior is said to be non-local and thus not subject to the limitations of the speed of light (which is a limitation of movement over a distance)
Quantum physics would say the interference pattern demonstrated by one-particle-at-a-time double slit experiments is the result of the interference between the probability waves for the two slits.
Einstein predicts that gravity waves (or any gravitational effects) are also bound by the speed of light. If you could somehow magically teleport the sun away to the other side of the universe, we wouldn't know or care until 8 minutes, when we would notice the sun blipping out of the sky and its gravitational effects vanishing.
