Question

Why are the Hubble Constant, the Cosmological Constant, and the density parameter so important to cosmology and to you? Consider expansion rate and age.

What would be different about our universe if the Hubble Constant were doubled from its current value?

How do these constants factor into the geometry of spacetime?

How have these constants changed throughout the lifetime of the universe? Are they still changing? Cite some evidence to support your claims.
