If most of the galaxy's mass is in the inner halo, what should the speed of rotation in the outer region be?
Most of the light from a galaxy comes from the inner parts. If this means that most of the galaxy's mass is also in the inner region, then how would we expect the galaxy's speed of rotation to behave in its OUTER region?
A. The rotation speed should decrease smoothly with increasing distance from the center, following a Keplerian curve.
B. The rotation speed should decrease sharply to zero at the outer edge of the visible galaxy.
C. The rotation speed should increase with increasing distance from the center.
D. The rotation speed should not change appreciably with increasing distance from the center (i.e., a “flat” rotation curve).

i think of the outer and inner worlds mirror one yet another. i do no longer lock the doors whilst i'm homestead and in simple terms relaxing ... till i'm having the kind of day that calls for solitude. I do lock the doors once I depart or visit sleep. i like to return back and locate each and every thing the place I left it. If somebody desires some thing, they are able to invite. If I even have it to grant, i'm going to. As for whilst i'm dozing, somebody coming in uninvited and waking me rudely could learn an entire new vocabulary ... and new makes use of for popular words.
