The Big Einstein's Theory Of Dark Matter And Dark Energy

2300 Words 10 Pages
Register to read the introduction… Einstein's theory states rules of gravity and its behavior. However, observations of gravity and the mass of the universe do not seem to come together very well. Scientists now need to add another piece to the Big Bang, dark matter and dark energy. The gravitational observations show that the universe must be much more dense than could possibly be with normal matter. Dark matter is defined by Shestople as "Any matter in the universe which does not give off any light of its own, or does not interact with light the way typical matter does" (1997, Glossary, A-E, para. 16). Dark energy is described similarly as energy that does not interact in a way typical of normal energy. Dark energy is required to explain the continuing expansion of the universe after so many billions of years. New data from the CMB estimates the amounts of dark matter and dark energy in the universe (see figure …show more content…

All of this seems to make perfect sense, but there are those who do not believe that the Big Bang is the end of the story. It is, after all, just a theory. There are alternate theories, though most lack the research that has been given to the Big Bang. The addition of theories to the Big Bang seems to be most disturbing to scientists who do not agree with the theory. Riccardo Scarpa (as quoted in Chown, 2005) states that "Every time the basic Big Bang model has failed to predict what we see, the solution has been to bolt on something new – inflation, dark matter and dark energy" (p. 1). As of yet, however, the only alternative explanations for dark matter and dark energy seem to require tearing apart the base of physics as we know it. Alternate theories on Newtonian gravity, such as modified Newtonian dynamics (MOND) are being researched (Chown, 2005, p. 4). Little to no backing on this research can be found at this
