I generally suck at maths so I could be all wet, but it seems to me that there is a problem of accuracy in Kafle's statement.
Kafle FTA: "Our home galaxy, the Milky Way, is over a trillion times heavier than our tiny planet Earth..."
Space.com: "Recent measurements have weighed the galaxy at between 400 billion and 780 billion times the mass of the sun. "
Swinburne Uni: solar mass is "about 333,000 times the mass of the Earth."
quick back-of-the-napkin calc: Milky Way is roughly 1x10^17 Earth masses.
That makes the article statement off by several orders of magnitude. That scale of error is like saying "more than 1000 people live in China." It's technically true but not realistically close to accurate.
UPDATE: Ah, I see my error now. Long form trillion, not "American trillion". See? Told you I suck at maths.
