    I have recently completed this fascinating online course by Paris Diderot University: Gravity! From Big Bang to Black Holes. Knew absolutely nothing about the subject - still know only the bare minimum. But as I'm now hooked I am determined to progress. I fear some of my questions may be too basic, but hope that you'll indulge me occasionally. Thanks.
