Frequently I found disparate values for the mass of the Earth. For instance, 5.9737 x 1024 kg and 5.97219 x 1024 kg are both quite common, not to mention the (older) 5.976 x 1024 kg. I know that...

I think they do not decay. I definitely know that inside the nucleus when neutrons are at the inner shells, they don't decay but I am concerned with the valence neutrons in nuclear shells. If...
