Question: Why did Einstein introduce the cosmological constant into the equations of his General Theory of Relativity when describing the universe?Einstein did not realize that black holes would exist at the centers of galaxies and pull everything into themEinstein's equations required the universe to expand or contract; he could not imagine or accept it doing either

Suppose the energy density of the cosmological constant is equal to the present critical density ε Λ = ε c,0 = 4870MeVm − 3. What is the total energy of the cosmological constant within a sphere 1AU in radius?What is the rest energy of the ? Comparing these two numbers, do you expect the cosmological constant to have a significant effect ...

Question 1 (15 points) The cosmological constant (Λ) term in the Friedmann equation acts to increase the expansion rate of the Universe. Cosmologists often refer to this effect as "Dark Energy" and use the term "Dark Energy" as a synonym for the cosmological constant.

Question: Why did Einstein introduce his cosmological constant into the original field equations for general relativity?Group of answer choicesThe constant was necessary to make the solutions describe an expanding universe.Experimental evidence at this time (before Hubble) suggested a static universe, and this constant was required to produce static solutions.The

The cosmological constant is the energy density associated with empty space. In cosmology, ...

Question: 2) Suppose the energy density of the cosmological constant is equal to the present critical density en = €0,0 = 5200 MeV m-3. a) What is the total energy of the cosmological constant within a sphere 1AU in radius? b) What is the rest energy of the Sun (E. = M.c?)?

For keyboard navigation, use the up/down arrow keys to select an answer. a He wanted to model a static universe b His friends told him to put it in с He wanted to ...

Suppose the energy density of the cosmological constant is equal to the present critical energy density of the Universe. In other words, ohm = 1, and rho c,0 c2 is derived from the critical mass density Calculate rho c, oc2 in units of MeV m-3. What would be the total energy due to the cosmological constant within a sphere 1 A.U. in radius?

Science; Earth Sciences; Earth Sciences questions and answers; According to the version of the Big Bang Theory without a Cosmological Constant (and without Dark Energy of any kind), what would be the maximum possible age of the universe in Gyr (Gigayears, meaning billions of years) if the Hubble Constant had the following values?

4.2 Consider Einstein's static universe, in which the attractive force of the matter density p is exactly balanced by the repulsive force of the cosmological constant, A- 4 TGp. Suppose that some of the matter is converted into radiation (by stars, for instance). Will the universe start to expand or contract? Explain your answer.
