Got 5 minutes? Watch this video, it will blow your mind. If you already know about the experiment skip a minute or two, but don't miss the end of the video. I did this experiment in a physics class at K-State, but I never heard of taking the experiment one step further:
After a couple minutes of thinking the best answer I came up with was that the world is based on infinite approximations, and so things that should happen, do happen. However, when we observe something, it isn't an approximation anymore and we see one instance of the process that is usually approximated. So there is something to us that is different than the rest of matter, there has to be, it's not like putting a coffee cup next to the slits makes light act different...
I need to know more about this. I would assume they tested this with the machine that was used for observations turned on and off, and that gave them different results. But what if the data is collected and then immediately destroyed so that no-one can ever see it, then how does the light act? What if the recording machine has a random number generator that turns it off and on, but no one knows the number that it picks, or if the machine is ever off or on. Can we observe how the light particle acted to tell if the machine was on or off?
Some people think that science will at some point eliminate the need for God, to me the more we learn about science the more it proves that there is God.
The universe is more amazing than we can imagine, and we barely know anything about it.
