|Pedants' Corner - How much does a white dwarf weigh?
||[Dec. 14th, 2005|04:22 pm]
Hubble weighs closest white dwarf says the BBC. Only it didn't. As the first sentence of the article says, it was used to measure the mass.|
As weight measures the force of attraction between two objects due to gravity then, especially when talking about space (where the acceleration due to gravity varies), it is not interchangeable.
Update: perhaps unsurprisingly, they've now corrected it.
