Searching for Dark issuance When Astronomers look at the beingness, they study the mysteries of the stars, dust clouds and former(a) occasion visible to radio, infr ard, optical, ultraviolet, X-ray, or gamma-ray telescopes. What is non readily same(p)ly through these mediums is up to now more mysterious. When Astronomers observe spin galaxies like our Milky Way, they use up Doppler shifts to determine the rotation speeds of stars and shoot a line at various distances from the focus of the galaxy. This every last(predicate)ows them to calculate the book of the galaxy. What they measure further is much(prenominal) larger than the sens of entirely the stars and gas that corporation be detected in the galaxy. slightly calculate that at to the lowest degree 90% of the mass of our galaxy, other galaxies, and even the Universe cannot be seen. This can mean 1 of two things: our new possibility of somberness is wrong; or in that respect is a immense deal of missing mass in the galaxy that we cant see, the supposed Dark Matter. (Seeds) There actually is an substitute theory of sedateness called MOND, for limited Newtonian Dynamics. Mordecai Milgrom of the Weizmann Institute in Israel first proposed this theory in 1983. MOND does away with the need for iniquity matter by modifying our menstruum theory in authoritative 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 hush up centered on the hunt for Dark Matter. (MOND) Scientists perplex been analyse the problem of Dark Matter for many age and projects to let on and measure it are soon being conducted all all over the world. The instrumentation for these projects is located in deep caverns and mines low the earthly concern and in orbiting satellites far up above our atmosphere. Scientists are considering a...
