What mechanism can simultaneously solve both the flatness and horizon problems in cosmology?
If the mass-density of baryonic matter is rhoM = 10^-28 kg m^-3 and the current temperature of the cosmic microwave background is T = 2.7 K, calculate:
(a) The mass-density of radiation (i.e rhoR)
(b) The photon-baryon ratio
(c) The temperature when rhoR = rhoM
Calculate the mass in GeV/c2 of a virtual carrier particle that has a range limited to 10−30 m by the Heisenberg uncertainty principle. Such a particle might be involved in the unification of the strong and electroweak forces.

- Because of the cosmological expansion, a particular emission from a distant galaxy has a wavelength that is 2.00 times the wavelength that emission would have in a laboratory. Assuming that Hubble’s law holds and that we can apply Doppler-shift calculations, what was the distance (ly) to that galaxy when the light was emitted?arrow_forwardDiscuss the relation E=mc2 and its importance.arrow_forwardIs the Hubble constant actually constant?arrow_forward
- (a) What Hubble constant corresponds to an approximate age of the universe of 1010 y? To get an approximate value, assume the expansion rate is constant and calculate the speed at which two galaxies must move apart to be separated by 1 Mly (present average galactic separation) in a time of 1010 y. (b) Similarly, what Hubble constant corresponds to a universe approximately 21010years old?arrow_forward(a) What Hubble constant corresponds to an approximate age of the universe of 1010 y?

- If the average density of the Universe is small compared with the critical density, the expansion of the Universe described by Hubble's law proceeds with speeds that are nearly constant over time. Calculate t since the big bang, assuming H = 22.0 km/s/Mly.arrow_forwardAssuming the matter temperature equalled the radiation temperature at the recombinationepoch, evaluate MJ in a Friedmann universe of a given (h0, Ω0) with the present temperatureT0 = 3K of the microwave background.arrow_forwardEdwin Hubble observed that the light from very distant galaxies was redshifted and that the farther away a galaxy was, the greater its redshift. What does this say about very distant galaxies? When Hubble first estimated the Hubble constant, galaxy distances were still very uncertain, and he got a value for H of about 600 km/s per Mpc. What would this have implied about the age of the universe? What problems would this have presented for cosmologists?arrow_forward
