Asexuality is distinct from the condition of people who lack sexual desire but find that problematic. 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.

Red Shift. The light from distant stars and more distant galaxies is not featureless, but has distinct spectral features characteristic of the atoms in the gases around the stars. When these spectra are examined, they are found to be shifted toward the red end of the spectrum. This shift is apparently a Doppler shift and indicates that essentially all of the galaxies are moving away from us. Using the results from the nearer ones, it becomes evident that the more distant galaxies are moving away from us faster. This is the kind of result one would expect for an expanding universe.
