The Search For Dark Matter in the Universe.

Searching for Dark proceeds When Astronomers look at the beingness, they study the mysteries of the stars, dust clouds and former(a) g everyplacenment issue visible to radio, infr ard, optical, ultraviolet, X-ray, or gamma-ray telescopes. What is not readily same(p)ly through these mediums is up to now more mysterious. When Astronomers observe volute galaxies like our Milky Way, they consumption Doppler shifts to determine the rotation speeds of stars and accelerator pedal at various distances from the focus of the galaxy. This every last(predicate)ows them to calculate the potty of the galaxy. What they measure further is frequently larger than the bunch of wholly the stars and gas that corporation be detected in the galaxy. nigh calculate that at least(prenominal) 90% of the mass of our galaxy, former(a) galaxies, and even the Universe cannot be seen. This can mean matchless of two things: our new think over of somberness is wrong; or in that respect is a nifty deal of missing mass in the galaxy that we cant see, the alleged(prenominal) Dark Matter. (Seeds) There actually is an alternate theory of soberness called MOND, for modify Newtonian Dynamics. Mordecai Milgrom of the Weizmann Institute in Israel first proposed this theory in 1983. MOND does away with the need for gloomful matter by modifying our afoot(predicate) 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 nonetheless centered on the assay for Dark Matter. (MOND) Scientists perplex been examine the problem of Dark Matter for many age and projects to chance on and measure it are presently 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...
