"The good thing about science is that it's true whether or not you believe in it." Great quote. Here are some other GEMS that he said (the second one may be a bit paraphrased by me, from my memory, so don't be surprised if it's VERY slightly different if you find the video of him saying it):
1. "14 pounds of grey matter" (when referring to the human brain) 2. "A stack of one trillion one dollar bills would go to the moon and back 4 times" (figure it out for yourself, just HOW FAR OFF this is - I'll give you a hint if you don't want to go to the trouble, it wouldn't make it TO the moon once, let alone a round trip, let alone 4 - and he didn't say 3 or 5, he said specifically 4, which means he thought it was between 3.5 and 4.5 - that's a bit like me saying that Michael Jordan is 80 feet tall. Or 5 inches tall.) 3. After this, making such outrageous statements that no schoolchild should make, he had the GAUL to publicly criticize James Cameron for not accurately depicting the STARS IN THE SKY in Titanic as they appeared over the Atlantic ocean on that day at that time at that latitude and longitude. And BRAG about how he complained to Cameron and badgered him into redoing it and releasing another version with it corrected. As if that story was something to brag about. "Look at me, I'm an obsessive compulsive idiot!" And oh, of COURSE. Because such a trite detail of astronomy is so important, but NO OTHER field of science like BASIC anatomy - or BASIC MATH - is important enough to get even within a goddamn ORDER OF MAGNITUDE when making a PUBLIC STATEMENT about them in front of a camera that will be recorded for all posterity, in a speech I COULD have rehearsed, involving information I could have researched, and calculations I could have taken the time to do competently.
OH MY GOSH THAT IS SO AWESOME. Cosmos is one of my favorite shows. And my friend's dad worked with him when he worked at a planetarium, so they're good friends! Coincidentally, that story is what helped me decide what I want for my birthday.
It's a cool quote, but it isn't true. Science is mostly theory, and while some of it is more obviously accurate, much is not. The Observer Effect is a good example. Science is trying to describe reality as best it can, but that's often marred by exclusive academic groups which stifle insulting advancements. They don't even know what magnetism is, and it doesn't take a physics degree to figure it out.
