The death of the great scholar Vera Rubin, discovered evidence of dark matter
Astronomer Vera Rubin, aged 88, has discovered evidence of dark matter through the speed of galaxies.
She studied the spiral galaxies and observed that they were rotating at speeds different from what they should be. The speed of rotation of stars away from the center should be slower than near. The planets in the solar system - for example - spin around the sun at a slower speed as the planet is farther away from the sun, if not slower to be shot at the high speed outside the solar system, if only slightly lower to the sun.
The following graph shows two different lines. The bottom line is what scientists expect for the speed of the orbits of the galaxy (stars and other celestial bodies) relative to the distance between them and the center of the galaxy. The velocity increases and decreases as the contents move away. However, studies show that the content increases faster. The center, and so quickly will be thrown out of the galaxy, because gravity will be weak in the limbs, so there must be something attractive to hold the galaxy, and this thing is dark matter.
We know today that the dark matter is about 27% of the components of the acclaimed universe, but scientists do not know what the material is, the research continues to understand the mm formed.
Vera presented Princeton University, but did not receive admission to the astronomy program. The astronomy was confined to men until 1975. She accepted at Cornell University and completed her astronomical career.
She thinks she deserves the Nobel Prize, but she did not get it ... Goodbye, you great scientist.
