I find it fascinating and I welcome the improvements scientists have made in understanding the world we live and the universe as a whole. As of late we have been able to see galaxies and worlds we had no idea that existed. It's not just empty space out there. This is the area of my interest. the universe. I think being bp makes me more stimulated to this field because much of the time I feel I'm more out there than in here. LOL. thank you Ganesha for these fascinating insights. I hope there's plenty more where that came from. TgrsPurr.
