Assuming 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.
Suppose a spaceship has the mass of a typical ocean cruise ship, then it can be assumed that it has a mass of 4.3 x 108kg. Consider the Kendrick energy required at 17% of the speed of light. If energy to get a spaceship to cruising speed is generated using matter-antimatter annihilation, what mass of antimatter in kg is required ?
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.

Convert this to eV/c2.m3 .arrow_forwardNow let’s determine when the universe “started its trip”. The distance is 800 Mpc, but first convert Mpcinto km because the rate, or velocity, is in km/sec.800 Mpc = _____________________kmUse equation (E) to determine how many seconds ago the universe started:_____________________secsarrow_forwardConsidering the reactions in primordial nucleosynthesis only, what would be the impact on the universe today if the neutron lifetime were much smaller than 886s (the actual value of the neutron lifetime)?arrow_forward
- An electron jumps from n=3 to n=2 in a hydrogen atom in a distant galaxy, emitting light. If we detect that light at a wavelength of 3.00 mm, by what multiplication factor has the wavelength, and thus the universe, expanded since the light was emitted?arrow_forwardBecause 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_forwardSuppose you measure the red shifts of all the images produced by gravitational lensing, .You findthat the central image has a red shift less than the outer images, and those all have the same red shift. Discuss how this not onlyshows that the images are of the same object, but also implies that the red shift is not affected by taking different paths throughspace. Does it imply that cosmological red shifts are not caused by traveling through space (light getting tired, perhaps)?arrow_forward
- Suppose that the universe were full of spherical objects, each of mass m and radius r . If the objects were distributed uniformly throughout the universe, what number density (#/m3) of spherical objects would be required to make the density equal to the critical density of our Universe? Values: m = 10 kg r = 0.0399 m Answer must be in scientific notation and include zero decimal places (1 sig fig --- e.g., 1234 should be written as 1*10^3)arrow_forwardExplain why it only appears that we are at the center of expansion of the universe and why an observer in another galaxy would see the same relative motion of all but the closest galaxies away from her.arrow_forwardSome theorists expected that observations would show that the density of matter in the universe is just equal to the critical density. Do the current observations support this hypothesis?arrow_forward
