Astronomy 123: Second Homework Assignment
You may, as before, work on this assignment with groups of other
- Be Edwin Hubble and determine the expansion of the Universe using
the simulation of The Hubble Expansion Law
and answer the questions therein.
(you probably need to be using Internet Explorer version 5.5 or
above for the simulation to run).
- What was Supernova 1987A and what were some of the things that were
learned from it.
- Suppose you were arguing with someone about the Age of the
Earth and your foe had an intrinsic distrust of science and its methods
and so therefore would not believe anything to do with radioactive
age dating. Outline what points of "common sense" about the nature
of the Earth that you could use to demonstrate that the Earth is geologically
old. You might want to consult this reference
for some ideas.
