I think it might be the opposite. The appearance of a physical world is created by consciousness.
Interesting idea!
One of the reasons I believe this is my understanding of what scientists see when observing the smallest particles possible. I've read that subatomic particles only exist as particles while they're being observed and measured by a conscious being. Until then they're just waves of energy.
You may be referring to behaviour such as displayed in the double-slit experiment with light or you are maybe referring to the uncertainty principle in quantum mechanics?
If not please state a source as I really like this type of stuff :-D
Anyway, as far as I know it's not so much that a conscious being observing the waves changes them into particles. It's just that for some phenomena it's impossible to measure all properties very exact at the same time. And sometimes observing/measuring one of those properties very exact, makes the other one almost impossible to measure or predict.
For instance, the double slit experiment gives the same result if no conscious being is watching them, but it's results are recorded for later viewing.
If this is true then it might also be true that the entire material world doesn't exist unless consciousness is observing it.
Does that mean that the material world you are observing is not the same as the one I am observing?
And we also know that we can take away a person's consciousness by changing his material properties.
E.g. I can remove your consciousness from my world by destroying or damaging your material body.
Or I could pause your consciousness by adding chemicals to your body (anaesthetics), and bring back your consciousness by removing the chemicals.
If the material world follows from our consciousness, I would think that would be impossible?
