Observations of Type Ia supernova indicate that the universe is static.

The orbits of halo stars are typically circular and have a low inclination with respect to the disk.

Evidence for a very early “super rapid” inflation of the universe is that the 3-K radiation from opposite sides of the sky (i.e., 180 degrees or about 28 billion light years apart) is of nearly ___________ intensity. Time for light to travel this distance is ___________ the age of the universe in years.

___________ galaxies contain large clouds of gas and dust, both young and old stars, but have no obvious spiral arms or nucleus.

Getting a cold is like building the chemical elements in nucleosynthesis.

The deuterium and lithium-7 in distant quasars and in the interstellar medium suggests that the Universe is open.

Elliptical galaxies contain more gas, dust, and young stars than do Sa galaxies.

A center or an edge of the Universe would be a special place, contradicting the cosmological principle.

Isotropic is the same as homogeneous.

For a galaxy to be active, the supermassive black hole needs to have matter flow into it.
