Milky Way a Swifter Spinner, More Massive


www.nrao.edu
Fasten your seat belts -- we're faster, heavier, and more likely to collide than we thought. Astronomers making high-precision measurements of the Milky Way say our home Galaxy is rotating about 100,000 miles per hour faster than previously understood.

That increase in speed, said Mark Reid, of the Harvard-Smithsonian Center for Astrophysics, increases the Milky Way's mass by 50 percent, bringing it even with the Andromeda Galaxy. "No longer will we think of the Milky Way as the little sister of the Andromeda Galaxy in our Local Group family."

The larger mass, in turn, means a greater gravitational pull that increases the likelihood of collisions with the Andromeda galaxy or smaller nearby galaxies.

well, I am not such an ignorant. I've been reading quite a lot of books about our solar system (best I got lately is Brian Bryson's "a shot story of nearly everything").
mu question was more sarcastic. it is why the hell thay are trying to say that for example there is no way for yellowstone to erupt, or there are no big objects on the collision with earth instead of confirm that they have no idea of such.

its my view that If we were around long enough , around 15 billion years,
we would have enough records & measurements to prove that the Milky Way Galaxy is continuing to grow, or else is creating more stars & mass from the dark matter' which surrounds our galaxy.

Perhaps in another 15 billion years , the Milky Way will expand to become the 'observable universe' we are in ...
as all the other far flung galaxies will have retreated past the 14 billion year visual boundary


thanks
