NASA accurately calculates Milky Way's weight using Gaia, Hubble telescopes

Here's Ann. Is this a surprise?

"Weight vs Mass? Is there a difference?"

[Verginius Rufus]

Everyone should start their own conservation of mass program. We don't want to cause the Milky Way to tip over. Maybe it would help if all the litter was picked up and burned.

And definitely do not build any more military bases on Guam. That could be disastrous for the galaxy.

[ProtectOurFreedom]

Good Lord? What if my extra mass gets transferred to Alpha Centauri? Will that upset the natural balance in the galaxy?

[SuperLuminal]

"...thanks for the new background for my desktop display...it's lovely."

Ditto!

Particularly since my galactic weight calculations may not be "accurate" but they are precise... NASA has clearly missed the galactic weight by 126 lbs and 11 ounces... I understand that NASA actually used the weight stated in the quran...

10 to the 42nd power. Once again proving that the hitchhikers guide to the galaxy is correct.

[Verginius Rufus]

Closer to home, the planet is going to be destroyed by plastics in the ocean, if SUV’s don’t destroy it first. And in the long run the galaxy may be doomed by the impending collision with the Andromeda Galaxy. Unless Cetus devours Andromeda before that happens.

Ding ding ding. You have won today's internet 😁!

[Captain Compassion]

You could also sink the Galaxy in a vat of water and check it’s displacement.

I wish they’d spend this much money and effort to cure liberalism.

It could revolutionize the world.

“NASA accurately calculates Milky Way’s weight”

Milky Way Shamed into Joining Jenny Craig!

Becomes New SpokesGalaxy!

[Izzy Dunne]

Does anything really have weight in space?

You're right. ESA got it right; Fox screwed it up. Never let a reporter talk about science.

The WEIGHT of something depends on how close it is to something ELSE (like a planet or star). The MASS of something is a measure of how much material is in it, and doesn't change because of location.

[spudville]

Think of it as one less thing praying on your mind constantly like an annoying song. On to the next question that the voice in my head keeps repeating.

[SMGFan]

I prefer the taste of Milky Way Midnight Dark

[Swordmaker]

Really? Accurately? Weight? Is that at one G? Or do they really meany so "inaccurately", since they appear to not even grasp the terminology correctly, "the mass of the Milky Way Galaxy accurately." Finally, how much magic fairy dust (dark matter) did they just toss in—just because—to make their Newtonian calculations work.

These orthodox gravity astronomers and cosmologists refuse to consider an alternative that explains everything they see in the Hubble and other deep space telescope probes they are at a complete loss to explain using their gravity-as-an-explains-everything models. That is the Electric/Plasma Universe theory which recognizes that the also infinite reach of ElectroMagnetic forces moving in Plasmas which are 10³⁹ times stronger than the very weak attractive power of gravity, actually drives the universe and if recognized, does not require the invocation of either dark matter or dark energy to explain the observed phenomena that so challenges the orthodoxy to squish and squeeze their math by adding magic fudge factors to their calculations merely to "sort-of" get things to match what they see.—Electric/Plasma Universe PING!

Thanks Swordmaker. This will help fill in that last puzzle in physics, an accurate measurement of the speed of dark.

[Hot Tabasco]

And for what purpose?

[Hot Tabasco]

he Milky Way weighs about 1.5 trillion solar masses

My scale doesn't display solar masses. So how does this convert to pounds?

[stremba]

An electrically charged plasma would interact in known way with light coming from stars in the Milky Way. Those interactions are not observed, so no plasma.

What IS observed is that galaxies don’t rotate the way that should based on Newtonian gravity or General Relativity. Either our gravitational theories are wrong or there is some unaccounted for mass screwing up the calculations. Both of these possibilities have been investigated (Google MOND - modified Newtonian dynamics of you want to find out more), and reality matches better with the unaccounted for mass, I.e. dark matter.

I’m not really sure why massive particles that only interact gravitationally is such a problematic idea anyway. There are only four possible ways particles can interact—electromagnetic, strong, weak, and gravity. We already have detected particles that don’t interact via the strong and electromagnetic forces, namely neutrinos, which interact only via the weak force and gravity. Is it really such a stretch to think there might be neutrino-like particles that don’t interact via the weak force?

[ETL]

Weight is like force:
F=ma - W=ma, where a is the acceleration due to gravity.
