There are many such clouds in our Universe': They are assumed to contain nearly all of the matter between the stars. Gravity is a key to star evolution. You may recall that according to Newton's law of gravity, all ...

... Of the 15,000 stars, only 23 stars were in the targeted blue group. We found their average squared speed to be 72 km2/s2, which is half the value we found for the red stars, 144 km2/s2. These measurements have an uncertainty of only 10% of their values, so they strongly confirm the prediction of eq ...
