How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • The mass of a human: This is an illustrative comparison value, not a claim that every example is the same.

Mass is distinct from weight: an object’s mass stays the same as gravity changes.
