Neil deGrasse Tyson’s sequel/reboot to Carl Sagan’s Cosmos: A Personal Voyage, Cosmos: A Spacetime Odyssey, premiered last week on Fox and there’s a multitude of reactions to it. One of the most common negative reactions focuses on the episode’s relatively long segment on Giordano Bruno. If you really want to learn more about Bruno and the various other figures people relate him to and see one of the clearest criticisms and replies to defenses of the show, I suggest you look at the Renaissance Mathematicus’ post on the issue. (And if you want to learn REAL history of science, I highly suggest you check out the rest of his blog.)
A very religious friend posted concerns from Catholic commentators that Cosmos is attacking religion here. I argue that both just seem to be taking offense and ignore Tyson’s actual narration during and around this segment. At no point does Tyson criticize faith. If anything, it’s a critique of institutions which both blog posts seem to also acknowledge by saying that structures and actors in the Church may be bad, but that doesn’t mean Catholicism itself is bad. I’d argue the bigger takeaway is that Bruno thought others’ God was too small.
Several people have asked why mention Bruno at all in the show. Because the entire point of this first episode was to establish the scale of the Universe and our place in it. Bruno was one of the first Western thinkers to propose a Universe where humanity and Earth and the Sun are all small and not particularly unique with respect to the rest of the cosmos. though he was still off on how that actually worked out, as detailed in the Renaissance Mathematicus link above. To Bruno, that had immense philosophical implications and he was willing to die for them (and the host of other heterodox beliefs he held). Why should we just ignore that? Tyson (and Sagan!) are both big on the idea that science can inform metaphysics, and Western culture seems to have a fear that science will leave life without meaning. It seems perfectly reasonable for the show to mention a person whose cosmology inspired a lot of his own religious and spiritual thought.
Hank Campbell, founder of Science 2.0 and one of the co-authors of Science Left Behind, has different criticisms than most about the first episode, saying “Science is cool. Should we care if it’s accurate?” I want to quickly respond to these points, and I’ll go in more depth later.
- The greenhouse effect is in fact different from the idea of global warming, but the greenhouse effect does play a part in the latter.
- I kind of cringed too at the reference to a multiverse but considering the language the episode used, I’d say the phrase “many of us suspect [a multiverse]” was chosen precisely because it isn’t an accepted theory.
- The first time I watched the episode, I didn’t notice the external sounds in space separate from the soundtrack. It struck me as kind of funny because Tyson would typically destroy any show that did it. He should be held accountable on his own.
- The episode did not claim Bruno was more important than contemporary natural philosophers and empiricists and definitely pointed out that he wasn’t a scientist. Bruno’s ideas, though, do fit in well with the idea of understanding our place in the universe, which was the entire point of the first episode, as stated in like the first five minutes.
- The age of the universe as 13.8 billion years old was given multiple times, and the introduction to every major historical landmark on the calendar involved Tyson giving both its date on the calendar and a conversion to how many millions or billions of years ago it actually was.
