Misconceptions about the Big Bang (2005) [pdf]
- EGreg 11y agoIf space is expanding, though, wouldn't the space between our atoms be expanding also, and proportionally everything would stay the same to our bodies?
- ramchip 11y agoIt's explained in the article, under "Is Brooklyn Expanding?"
- blahdeeblah 11y agoNo. The article addresses this. The accelerating expansion of the universe exerts a small outward force on objects, leading them to be in a steady state size that is very slightly larger than they would otherwise be.
- bonoboTP 11y agoI got curious and looked up the expansion rate of the universe. It's 74.3 km/s per megaparsec, in other words 2.4 × 10^-18 Hz, or about 8 × 10^-11 year^-1. So each year one meter becomes one meter + the size of a hydrogen atom. Not very quick.
