"The Milky Way weighs in at about 1.5 trillion solar masses (one solar mass is the mass of our Sun), according to the latest measurements. Only a few percent of this is contributed by the approximately 200 billion stars in the Milky Way and includes a 4-million-solar-mass supermassive black hole at the center. Most of the rest of the mass is locked up in dark matter, an invisible and mysterious substance that acts like scaffolding throughout the universe and keeps the stars in their galaxies."

l like the air of darkness, invisible and mysterious in the release..."resistance is futile"

How does anything have weight in zero gravity?

Space has zero gravity, where there is no mass. They are talking about masses which have gravity.

It doesn't. The piece is using colloquial English.


You know, I was thinking it was looking a little trimmer these days. Must be the treadmill!

Milky Way, I feel you. I felt that way after my hoard of Xmas cookies.

It must have taken them months to go out on a rocket with a scale to weigh everything.


Ooooh! Facts are sexy!
