Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I am reading Brian Greene's new book "The Fabric of the Cosmos".

In the book, Brian Greene talks about the Quantum Measurement Problem, different interpretations of QM, decoherence, etc...

Rather than attributing the collapse of the probability wave to things like conscious or human observation, the book talks about matter and energy interacting with matter as causing its decoherence.

First off, am I understanding it correctly?

If so, isn't it basically saying that everything is built upon and dependant upon everything else?

If so, where and/or when did the initial decoherence take place that caused everything else's probability wave to collapse? Could the Big Bang have been the collapse of the universe's probability wave? Does the question of where and/or when even have any meaning in such a universe?

Thanks for any help or insight into making sense of all this.
