neilep - you make sense. We have to understand the rules and nature of this Universe. But there may be Laws that we don't understand because we cannot see or measure them objectively. The article I was talking about involved the entanglement of photons passing through polarisation filters.

I still find it difficult to understand but the broad conclusions are that there is no objective reality until a measurement brings it into being - supporting Bohr and Heisenberg. This is a bit spooky.

What you have to ask, in broad terms, what does science tell you?

Science does not tell you what reality is - your own senses tell you that, and you either believe them or you do not.

What science excels at is telling you what will happen.

When Newton formulated the theory of gravity, he could not really say whether something called gravity really existed. What Newton did was he created a set of mathematical models that predicted what would happen to a massive object in the vicinity of another massive object. He said that if he had an observable apple, and dropped it, it would fall, and it would repeatedly fall, and the rate of fall could be consistently calculated using a mathematical model of the behaviour of massive objects. Who can say whether gravity exists or not, but we know the maths works (apart from the adjustments made to the mathematical model by Einstein).

The same is true of quantum physics. Who can say if quantum physics describes a real world or not, but we know that the mathematical model it contains makes accurate predictions of observable events - we know no more than that.
