Each time I hear the world’s top physicists change their minds about how fast the universe is expanding, or how much it’s curved, or where, when and how the Big Bang originated - whether there even was a big bang - I chuckle to myself and think - jeez.. these guys don’t know what the f they are talking about.
I agree. Their ideas change every now and again. I found a chemistry book from a garage sale from the 1940’s and in it, they said a neutron was a collapsed electron or some such. It would tire of spinning around and slam into a proton, and then their charges would cancel out. That is what was taught in schools.
