“Everyone should wear a mask,” Blumberg said. “People who say, ‘I don’t believe masks work,’ are ignoring scientific evidence. It’s not a belief system. It’s like saying, ‘I don’t believe in gravity.’"
בהשגחה פרטית this past week there's a Hayom Yom that some people struggle with, thinking that it somehow denies gravity:
In actuality, this doesn't at all deny gravity, and is probably fully in-line with current astrophysics. The Alter Rebbe isn't saying that gravity doesn't exist, he's saying that attributing not falling off the face of the earth on the other to gravity is the wrong answer. What the Alter Rebbe is saying is that the entire premise of question is wrong, as there is no real upper and lower side to earth.
