There are two independent Friedmann equations for modelling a homogeneous, isotropic universe. The first is: a ˙ 2 + k c 2 a 2 = 8 π G ρ + Λ c 2 3 {\displaystyle {\frac { {\dot {a}}^ {2}+kc^ {2}} {a^ {2}}}= {\frac {8\pi G\rho +\Lambda c^ {2}} {3}}} which is derived from the 00 component of Einstein's field equations.

The force-free limit of the Grad-Shafranov equation allows us to analyze in detail the physics of the The Strongest Magnetic Fields in the Universe.

What’s in an equation? Letters and numbers and odd symbols — but also a novel insight into the relationships between fundamental constituents of our physical reality. All equations crystallize something important about the universe, whether it be the relationship between mass and energy, the gravitational attraction between two bodies or

Our model only modifies the pressure of matter, so the cosmic history before the matter-dominated era is almost not effected and we only consider the later time. From observations we know that the universe is always expanding, so ρ m is decreasing with time. If matter and radiation do not interact, as is assumed, we can write down energy conservation laws for them separately. Then for radiation $\rho_{r}\sim a^{-4}$ and for matter $\rho_{m}\sim a^{-3}$, so energy density of radiation in an expanding Universe always decreases faster than that of non-relativistic matter.

Then -1 comes in to represent the idea of 2 (dueling 1’s). *In a reversible process the total entropy of a system plus its surrounding is unchanged. delta S univ = 0.

Given that the universe is accelerating, the next immediate question is whether the acceleration is caused by a strictly constant vacuum energy or something else; the obvious place to look is for some time-dependence to the dark energy density. A Fischer F riedmann’s equation and the creation of the universe 16. W e note that in these three mo dels, the age of the universe t 0 is model-dependent, as given in. T able 1. 2004-12-05 2020-09-14 2021-04-14 This equation laid the foundation of a very prominent branch of Astrophysics and also acted as a milestone in the study of plasmas. Being a plasma physicist, I am glad to discuss and explain this equation with you and share some history about it. So, let us try to understand how Saha’s equation helped in the spectral studies of stars.

Matter, material substance that constitutes the observable universe and, property of inertia, which—as formulated within Isaac Newton's three laws be converted into each other according to the famous equation E = mc2,

you'll never find a configuration where the magnetic force lines always point outward, or always point inward. So, for the formation of the universe the R.H.S of the Equation (6) has to be negative. During the early universe, the average spin of the fundamental particles (the source of Dark energy) is very high and therefore a negative pressure due to dark energy remains extremely high when compared to the inward thrust on the universe due to the Space surrounding the universe. 2010-05-17 To force his equations — which theoretically predicted the expansion of the universe — to remain still, Einstein invented the cosmological constant, λ. He multiplied the metric tensor in his equation, g , by the cosmological constant, leading to a term λ g , which adjusted his metric tensor acting on space-time.
