- The explanation mentions “Eight zeptograms” although Randall’s box says “4 zeptograms of dark matter.”
- The 4,800 daltons in the explanation is roughly the size of a small protein; for example, insulin is about 5,800 daltons.
- Randall’s box says it contains 4 zeptograms of dark matter. Could someone explain this? My incomplete (biologist’s) understanding of dark matter is that astrophysicists do not yet know what it is. So how could Randall claim the box contains 4 zeptograms of it?
Thanks!
