What are the biggest, smallest,& most numerous galaxies?
Can you explain the life story of the Universe? Big Bang to
the present. I am confused about what events took place
and in what order.
Explain these questions on the review sheet--
1. How many galaxies evolve?
2.Problems of Quasars?
3. Unified model of active galaxies?
4. what is expanding in the expanding universe?
THANK YOU
