I found David Butler's more simplified "picture" on the various programs dealing with humans and our quest to understand space and time, to be quite enjoyable. There's nothing new you'd learn from his series of 17 or so chapters, each about 15 minute long, re-summarizing in a high-school-ish way so everyone could understand space and the enormous distances between stars and galaxies.....
I turn this serious on every night, so I could listen to it, even as I fall asleep, so it is quite enjoyable.
Anyway, this one above, on the HELIOSPHERE, is quite haunting, when he allow the late Carl Sagan to speak... when, in the 1990s, when the space craft VOYAGER was about 4B miles from earth and Sagan requested that it was turned facing earth and take one picture before it ultimately exit our solar system.... on its way to places like Alpha Centaury, the nearest star system, which is 10 to the 6 AU away...
Carl Sagan said perhaps the most accurate, most haunting truth about the history of mankind and our fragility and ignorance... starting at 12:15 minute mark, when David Butler put up a simplified visual context to the vast distance between just our Sun and Alpha Centauri...
Every time I listen to these words of Carl Sagan, I have the most awe-inspiring thoughts and understanding about our species and our tiny earth and its insignificance in the midst of TRILLIONS OF TRILLIONS of other planets revolving around HUNDREDS OF TRILLIONS of suns which are themselves moving about the cores of HUNDREDS & HUNDREDS OF BILLIONS of galaxies....
And how truly lucky we are, those who are alive, who have the time to grow up and grow old and to learn things... things ranging from microbes, to big animals, to mountains and rivers, to moons and planets and suns and solar systems and space-time...
