Question
Following are the steps in the industrial synthesis of glycerin. Please find Step B
Assume that the Universe (near the present epoch) consists of two components," ordinary" (non-relativistic) matter (wm = 0) and "phantom energy" (x) with an equation of state wx = -4/3. Assume that for each of these components the present values of the density parameters are ohm m,0 = 1/4 and ohm x,0 = 3/4 (You might find useful that for these parametersH0t0 1 as in (6.32) of the book) Find the redshift, zmx, at which m = x. find the redshift, z, at which the acceleration of the Universe Vanishes. For this model find the present value of the deceleration parameter q0. This open, even expanding model has a finite lifetime (alpha rightarrow infinity for the t = t infinity > t0, how much time does it take (delta t tinfinity - t1) for the "big rip" (alpha rightarrow infinity )to occur? (Hint: for t1 >> t0 which component dominates?)Explanation / Answer
