Astronomy Unit 34 The three basic assumptions of modern cosmology include all of the following EXCEPT the universe is anisotropic One test of the curvature of space is the distribution of objects in space If the number of objects increases as r 3 then space is flat The Newtonian Euclidean cosmology can be essentially distinguished from others by the phrase A Euclidean geometry with particles obeying Newton s laws The evidence that the expansion rate of the universe is accelerating rather than decelerating is based upon the study of distant type of supernovae Euclidean geometry describes curved space incorrect If the average density of matter over large volumes varies throughout the universe then the universe is not homogeneous Cosmology is the study of the size and structure of the universe The big bang model predicts that most of the elements beyond helium form by stellar nucleosynthesis Mythological cosmology associates the universe with the spiritual life of humans The inertial mass of an object could be described as a relation between resistance and change of motion The log of 10 50 000 lies between 4 and 5 The text based upon known data at the time of publication gives 75 km s Mpc as the best current estimate of the Hubble parameter The essential content of Olbers paradox is that an infinite universe should have a bright night sky The deceleration parameter measures the rate of change of the expansion of the universe The idea of an isotropic universe means the universe looks the same from all points of view Which of the following have been propose as standard measuring rods for determining the curvature of space Radio sizes of radio galaxies giants elliptical galaxies Philosophical cosmology associated the universe with the power of reason Physical cosmology associates the universe with the force of gravity The big bang cosmology by itself cannot explain what existed before the big bang why the universe if isotropic The theory that the structure of spacetime is affected by the mass energy of the universe is the general theory of relativity Einstein introduced the cosmological constant into general relativity to allow for a static universe
