Clueless Astronomers

It’s great that they have this new more accurate understanding. However I can’t help but think how could they have bee 50% off? Are they going to revise their estimates next year? How sure are they this time around? I’d like a little historical data here. Perhaps in a time lapse view with the size of our galaxy changing over the years as our understanding has improved. How sure were they each time they came out with a new estimate? Surely there has got to be a way of putting boundaries on these estimates?

Milky Way faster and heavier than thought

WASHINGTON DC: The Milky Way is spinning much faster and has 50 per cent more mass than previously believed, increasing the chance of a collision with another galaxy, say astronomers.
An international team of researchers have used ten telescopes spread out between Hawaii, the Caribbean and the northeastern United States to determine that the Milky Way is rotating at a speed of 161,000 km/h faster than previously thought.
