The notion of Beautiful Big bang model was because of Gammow, and it also ends up one to having a believed light dominated universe, temperatures

That but not dont influence T(t) from any first idea as the ongoing out of proportionality on foregoing equation is not known.

You can nevertheless assign property value the new T(t) with presumptions in regards to the wished design, and you may which in a sense is some sort of tautology.

Simultaneously, accident are missing simply for an analytical fluid termed as “DUST” which has no tension, zero temperature

8. We all know that, the answer to the foundation off kinematical tension and you will temperature from a fluid ‘s the mutual crashes certainly one of the component particles.

In the ideal BBC, all test particles (galaxies in present era) are receding away from one another without any mutual collision. Thus in the ideal BBC, which involves assumptions of perfect homogeneity and isotropy, the fluid is a dust. This has been shown specifically by expressing g00 in terms of pressure and density (Mitra 2011a,b, 2012). The fact that g00=1 for the ideal BBM, leads to p=0. Then in the absence of any collision, temperature of the BBM fluid T=0 too. Thus ideal BBM should be COLD and not HOT.

nine. Energy is conserved having a system that has good timelike Killing vector. By listing you to definitely FRW metric has no particularly Killing vector, you can declare that complete time of the FRW market you prefer never be saved. But not, people system can obtain otherwise lose time just from the getting all of those other Universe.

Following Einstein’s definition of Lagrangian density and gravitational field energy density (pseudo tensor), Tolman (1930, 1962) derived a general formula for the total matter plus gravitational field energy (P0) of an arbitrary self-gravitating system (Landau Lifshitz 1962). And by using the Tolman ansatz, in a detail study, I worked out an expression for P0 for the FRW universe (Mitra 2010). It was found that

  1. So that number plus gravitation energy momentum occurrence is actually status separate, only the k=0 apartment model is admissible.
  2. To make certain that a free of charge falling observer observes no gravitational profession within his local Lorentz Frame, Cosmological Constant are no: Lambda =0.
  3. If opportunity momentum maintenance might possibly be broken, there might be emergence away from unlimited energy anyplace each time off nothingness. While energy preservation needs to be honored, FRW design must be Fixed and no contraction otherwise expansion.
  1. FRW market is largely static
  2. In the event the mathematically, you might layout an energetic FRW design, next, you should tacitly enjoys a vacuum model with rho =0, Lambda =0.
  3. Put another way, actual physical world with inhomogeneous shipments off lumpy number can’t be demonstrated by BBM.
  1. Stress of your liquid p=0 (as gotten earlier), or
  2. Universe is actually static: (overdot Roentgen) =0

As the we are these are a great SCALAR, which contraction cannot be told me away since people “enhance feeling”. At exactly the same time, particularly a contradiction will likely be fixed by the realizing that the brand new adhoc parameter

But also for the latest Market, there isn’t any Remaining portion of the World, meaning that the complete times (number in addition to gravitation) have to be saved

Since the most likely candidate getting Ebony Time of LCDM model are the one and only new Cosmological Ongoing, cuatro separate evidences one to L=0 strongly suggests that the new thus-called “Dark Energy” is an illusion arising from the new make an effort to explain advanced lumpy market from the an enthusiastic oversimplified design which requires prime homogeneity and isotropy (Mitra 2013b, 2014a).
