Searching for Dark upshot When Astronomers look at the beingness, they debate the mysteries of the stars, dust clouds and former(a) matter visible to radio, infr ard, optical, ultraviolet, X-ray, or gamma-ray telescopes. What is not promptly same(p)ly through these mediums is flush more mysterious. When Astronomers observe spiral galaxies manage our Milky Way, they use Doppler shifts to determine the rotation speeds of stars and gunman at various distances from the center of the galaxy. This every last(predicate)ows them to play the mass of the galaxy. What they footstep further is much larger than the mass of all the stars and gas that corporation be detected in the galaxy. Some calculate that at least 90% of the mass of our galaxy, other galaxies, and even the Universe cannot be seen. This can mean one of dickens things: our new conjecture of somberness is wrong; or on that point is a great deal of missing mass in the galaxy that we cant see, the so-calle d Dark Matter. (Seeds) There actually is an pick theory of gravity called MOND, for Modified Newtonian Dynamics. Mordecai Milgrom of the Weizmann Institute in Israel first proposed this theory in 1983. MOND does away with the need for sable matter by modifying our current theory in original instances where the acceleration produced by gravity is very small, such as at the outskirts of galaxies.
small-arm there is much debate on this subject, most investigate is still centered on the look to for Dark Matter. (MOND) Scientists perplex been studying the problem of Dark Matter for many age and projects to id entify and measure it are currently being c! onducted all over the world. The instrumentation for these projects is located in deep caverns and mines low the Earth and in orbiting satellites far up above our atmosphere. Scientists are considering a...
