The long and Winding Road to Relativity

I started this blog to work on Dark Energy and Dark Matter...from there I skipped to relativity with one's grandmother playing a role. Let me explain, for one to understand Dark E and M, it is best that relativity be understood to some extent. My final goal is to hit on Dark E and M. Between that relativity and a few other stories might come in. For the time, we will focus on relativity. Just to remind readers that I have not 'lost the plot'
