Tips on using the Site......
-
This overview of the Universe is intended to be complete
and straight forward, but not a
lot of detail to detract.
-
Don't take the theories described in this site as
gospel. They are likely to change many times just in our life
time. Rather view them for what they are...the best ideas at the present
time given the knowledge we have.
-
Do take the space photographs
seriously...and enjoy the wonder of the night sky. All the photos are
Courtesy NASA/JPL-Caltech, unless specifically noted otherwise.
-
A lot of the recent research and
discovery is
derived from a few magazines....Science News, a biweekly magazine,
Scientific American, and Sky and Telescope. I have found that
these magazines tend to give updates on the theories based on a representative
consensus in the scientific community.
-
The basic information regarding the universe and
how it got to where it is, is derived from years of reading books on astronomy,
science, and cosmology. I'd rather read The Red Limit than
Red October.
-
If you want more detail on any of the subjects
please see the web sites listed in Other Web Sites. There are some great
web sites which go into much more detail on the subjects covered here. These sites seem to me
to be the most professional and
objective.
-
Time is always given in millions of
years. This is so that when you see a number it is more easily compared to
other numbers. You don't need to say to yourself...."now was that
previous number referring to millions or billions?"
