When It Is All Over

Reading around about quantum mechanics this morning (sounds so important and smart, but really it was a kind of amateurish voyage inspired by another BBC documentary, my ultimate source of information about science and world in general), I came across this exchange:

Amusing SR style puzzle: when the universe dies in heat death in about 10^100 years where the last black-holes are decayed according to Hawking and classical matter has disintegrated to nothing, what will there be?

I came across this intersting blog – check it out. Here’s an example of the post discussing Quantum Mechanics and some of it’s philosophical implications (old theme, I know, but nonetheless still very exciting for yours truly):

Foundational studies of quantum physics hold a deep fascination for anyone interested in questions about the ultimate structure of the world. Quantum mechanics (QM) is now hovering around its 100th anniversary (depending on whether or not you take the work of Planck, Einstein, or Bohr to mark its true birth). Unlike other theories, quantum mechanics has proven to be remarkably elusive in terms of pinning down what truly, absolutely, no-kidding-anymore, really exists.


The Many-Worlds Interpretation seems crazy to a lot of people, physicists and non-physicists alike. Personally, as a theorist of the astrophysical sort, I see its allure but remain suspicious of the enormous commitment it asks. What may be most interesting about it, however, is how, by taking things to an extreme, it raises two of the oldest and deepest questions we can ask:

What truly exists, and what kind of access do we have to it?
