  1. Why are the Hubble Constant, the Cosmological Constant, and the density parameter so important to cosmology and to you? Consider expansion rate and age.
  2. What would be different about our universe if the Hubble Constant were doubled from its current value?
  3. How do these constants factor into the geometry of spacetime?
  4. How have these constants changed throughout the lifetime of the universe? Are they still changing? Cite some evidence to support your claims.

The Hubble Constant, the density of the universe, and the cosmological constant are all vital to the evolution of our universe. Briefly discuss why each is so important -and- what would happen if we tweaked each one up or down a little. Are there other constants that are equally important? If so, which and why?

Consider a flat expanding universe with no cosmological constant and no curvature (k=0 in the Einstein equations). Show that if the Universe is made of "dust", so the energy density scales like 1/a^3, then the scale factor, a(t), grows as t^(2/3). Show if it is made of radiation (so the energy density scales as 1/a^4 -- the extra factor of a comes from the redshift), then it grows as t^(1/2). In both cases, show that for early times, the scale...
