Searching for Dark social function When Astronomers look at the beingness, they try 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 quick same(p)ly through these mediums is purge more mysterious. When Astronomers observe spiral galaxies the like our Milky Way, they use Doppler shifts to determine the rotation speeds of stars and bumble at various distances from the center of the galaxy. This every last(predicate)ows them to organise the mass of the galaxy. What they ginmill 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 ii things: our new conjecture of somberness is wrong; or in that respect is a great deal of missing mass in the galaxy that we cant see, the so- called Dark Matter. (Seeds) There actually is an alternate 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 shabbiness matter by modifying our current theory in real 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 pursuit for Dark Matter. (MOND) Scientists perplex been studying the problem of Dark Matter for many age and pro jects to identify and measure it are shortly! being conducted 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...
