  1. Everything about the Universe and its origin BY SOUVIK ROY

  2. Introduction On Universe and its origin • We live on this planet but we don’t know about the entire universe. We don’t know how this universe creates. Some 15 billion years ago this universe appeared from a hot energy ball. Later this ball cold and create life on this planet • galaxies race away from each other, they move not through but with space, for space itself is expanding. The image often used is a loaf of raisin bread. As the dough rises, the raisins (representing objects in space, such as galaxies) move away from each other- and so does the dough they rest in. Expansion is a property ofthe universe as a whole and not just of galaxies.

  3. Discovery of the Universe Edwin Hubble first discovered that the universe is expanding in 1929. In the decades since then, astronomers have turned their attention to the implications of this finding. It countered pre- vailing ideas about the future of the universe, presumed to be a slowing down due to the pull of gravity from its matter, which would result finally in a collapse that some termed the “big crunch.’ With Hubble’s findings, astronomers had to grapple with the implications of a universe that is not only expanding but accelerating as it goes.

  4. WHAT’S DARK ENERGY? Dark energy is the reverse of gravity: It pushes things away rather than pulling them together. It is unknown whether the laws of physics or the general theory of relativity can account for dark energy. In 1998 astronomers studying supernovae found them dimmer than anticipated. This meant both they were farther away and the planet was expanding faster than expected. The U.S. government’s Joint Dark Energy Mission (JDEM) examined Type la supernovae, dying white dwarfs, because of their high and consistent luminosity. The programe 2010, and will be replaced by the Wide-Field Infrared Survey Telescope (WFIRST).
