The program shows that dark matter and dark energy are not needed to explain the equal speeds of the stars in galaxies and the expansion of the universe.
ravell Posted October 20, 2011 Posted October 20, 2011 The program shows that dark matter and dark energy are not needed to explain the equal speeds of the stars in galaxies and the expansion of the universe. Does the attached program can also show that the beginning of the the universe does not have to be a big bang, 13.7 billion years ago, but it can also be something quite different? And the expansion of the universe does not have to be a continuation of the inflation, but can only be a process of condensation of matter in an unlimited space? Can anyone were wondering over this, already?
ravell Posted April 15, 2012 Posted April 15, 2012 (edited) The program shows that dark matter and dark energy are not needed to explain the equal speeds of the stars in galaxies and the expansion of the universe. The Sagitarius BR program is cool and gives a surprising explanation of dark matter and dark energy. But in the version 3.0+ available in the above link, the calculation of the speed of the universe expansion has been limited to the interaction between neighboring clusters only. This makes that to obtain the Hubble parameter, it must be used a fairly high rate of contraction of the clusters. Is it already available an up-grade of this program, which takes into account in calculating the impact of the other more distant clusters? Edited April 15, 2012 by ravell

Although most still believe there is much evidence to support the idea that there is something there that may behave like matter there still is no evidence for its character, or even to say for sure that it is matter -- see the science news section of this forum concerning -- is dark matter really matter? Most would agree that at least it is a placeholder for something that we still don't understand. Dark energy is also just theory. The Nobel Prize was recently granted for its discovery but it too may be only a placeholder for something still not understood concerning what it is. There are a great number of hypothesis concerning both of them but the related observations are often not confirming the related theories. Once you read the Wiki pages on both you can understand present ideas of them concerning their educational value. Beyond that ideas can be quite speculative. // Edited April 19, 2012 by pantheory

A newer version of Sagitarius BR does not exist yet and I do not know when it might appear.
