NASA accurately calculates
about 1.5 is accurate?

“accurately calculates”? How could this be known? I’m just sayin’
To: ETL
Really? What's so complicated about that? It tells you the weight right on the package...2.05oz (at least, that's the weight this week).

If they can calculate weight, that means they should be able to calculate size. How far is it to the edge of the universe?

And, it's obvious NASA had their top scientist on it...

Does anything really have weight in space? Doesn’t weight have to have gravitational properties surrounding it.

Yeah, but now we know there are 3,000,000 times the solar mass of the sun of dark matter, in with that 2.5 oz.

The solar mass (M☉) is a standard unit of mass in astronomy, equal to
approximately 2×1030 power kg.
...and contrary to conditions on earth, astronomical photos have a slimming effect such that the Milky Way looks 10 pounds lighter that it is.

Good catch. And you’re right. The title should have been: NASA accurately calculates Milky Way’s mass.
An error like that kinda makes you wonder about the rest of the article.

Dark matter is an assumption to explain galaxy shape using gravity only.
What about electromagnetically charged plasma? That force would produce observed shape and does not require imagined matter.

Next, they turn their sights on Rosie O’Donnell and Michael Moore. But not at the same time ...

1 solar mass = 1.989 × 10
30 kg
1 trillion = 1 x 1012
Mass of Milky Way: 1.989 x 1042 kg
That's a BIG number. I've got my own conservation of mass program underway where I'm trying to transfer a few kg from my own mass back to the Milky Way. The Milky Way is welcome to my extra kg.
To: Cowboy Bob
Supposedly the earth is weightless. But it is also said to weigh 6.585 sextillion tons (that's 10 to the 21st power). The sun has 333,000 times the mass of the earth. So if the Milky Way's mass is 1.5 trillion times the mass of the sun, the weight of the Milky Way should be something like 3.3 duodecillion tons (or 10 to the 39th power).
But my math could be wrong. To get the weight in pounds, multiply by 2,000.

How hard can it be to weigh MilkyWays? They only have one Star.
