WebDec 3, 2024 · $\begingroup$ @xabdax The stellar mass density in the arms is a factor of 2-3 higher in the arms than in between (e.g. Rix & Rieke 1993). In the bulge, I think the stellar mass density is more like 5 times higher; I can't find any data right now, but the MW bar has a density roughly 5 times higher than outside the bar (Portail et al. 2024).

The sudden scrabble to develop defences against physical weapons REALLY should have started when the humans began to have interest in Mass Drivers capable of firing over 1,000 tons at FTL speeds.

4. MASS DISTRIBUTION IN DISK GALAXIES

WebOther articles where galactic mass is discussed: Milky Way Galaxy: Mass: The total mass of the Galaxy, which had seemed reasonably well established during the 1960s, has become a matter of considerable uncertainty. Measuring the mass out to the distance of the farthest large hydrogen clouds is a relatively straightforward procedure. The … WebAssume that a typical white dwarf has a mass of 2 x 10 30 kg. Given: unseen mass in Milky Way of 1.8e42 kg, mass of white dwarf is 2e30 kg. Concept: divide the unseen mass by the mass of a white dwarf to find out how many white dwarfs it would take to make up the unseen mass: (1.8e42 kg)/ (2e30 kg) = 9e11 white dwarfs. swallowing live fish
