There has been lots of research on hypoactive sexual desire disorder, which is classified as a personality disorder, and it is if you do not experience sexual attraction and it's causing you suffering.
Best Answer: Instruments on Hubble can measure Doppler's Shift of the light of galaxies. If the galaxies are moving away from us there is a Red shift of the light. And at what angle.If the galaxies are moving toward us, there is a Blue shift in the light. And at what angle.Then use semi-complex math to figure how the galaxies are moving in their calculated position in the Universe.est Answer: Instruments on Hubble can measure Doppler's Shift of the light of galaxies.

Our findings are statistically consistent with a head-on collision between the Andromeda galaxy and our Milky Way galaxy, said Roeland van der Marel of the Space Telescope Science Institute (STScI) in Baltimore. The solution came through painstaking NASA Hubble Space Telescope measurements of the motion of Andromeda, which also is known as M31. The galaxy is now 2.5 million light-years away, but it is inexorably falling toward the Milky Way under the mutual pull of gravity between the two galaxies and the invisible dark matter that surrounds them both.
