Almout four years ago, I started a thread in the P&R forum named "Gravitational Waves Detected" - I don't know why I put it there, but it seemed to be well-received and generated a lot of activity.
It might have done even better if it had been placed in the main forum - there are a number of people on the board that never venture into the P&R forum, and they may have enjoyed reading through the many thoughtful posts that populated that thread, and perhaps would have contributed.
So this thread is a follow-up to that one, but with a wider scope: anything in the STEM fields (science, technology, engineering, and mathematics).
I'll kick things off with this article on
quintessence, a form of dark energy that may explain why the universe is expanding faster than all the current models predict.
