An Historical Overview of our perspective on the Universe
Posted: Thu May 03, 2007 7:30 pm
Once Upon A Time:
The earth was the center of the universe,
http://csep10.phys.utk.edu/astr161/lect ... totle.html
http://en.wikipedia.org/wiki/Ptolemaic_system
It was flat,
http://home1.gte.net/deleyd/religion/ga ... earth.html
http://www.lhup.edu/~dsimanek/fe-scidi.htm
Then it was round, and it circled the sun.
http://www.bluffton.edu/~bergerd/NSC_111/science3.html
http://csep10.phys.utk.edu/astr161/lect ... nican.html
It was no longer the center of the universe, it was a tiny part of the Milky Way.

http://antwrp.gsfc.nasa.gov/diamond_jub ... lplan.html
http://cosserv3.fau.edu/~cis/AST2002/Le ... Trans.html
The Milky Way was the only galaxy,

http://www.1911encyclopedia.org/Nebula
[the Great Spiral Nebula in Andromeda was early on thought to be wholly within our galaxy.]
Except it wasn’t,
http://en.wikipedia.org/wiki/Andromeda_Galaxy
http://www.noao.edu/image_gallery/galaxies.html
http://www.damtp.cam.ac.uk/user/gr/public/gal_home.html
It was only one of billions of galaxies, floating in space without end.

Every single time we think we’ve got it all figured out, we realize we’ve merely found another piece of the picture.

http://www.space.com/scienceastronomy/d ... 50228.html
http://record.wustl.edu/news/page/normal/4768.html
It is a big picture, with many pieces.

http://en.wikipedia.org/wiki/Universe
http://en.wikipedia.org/wiki/Observable_universe
Sir Isaac Newton was the first to state the Law of Gravity.
http://www.grc.nasa.gov/WWW/K-12/airplane/newton.html
http://en.wikipedia.org/wiki/Isaac_Newton
Eventually everybody agreed that gravity alone formed galaxies and stars and planets,
http://science.hq.nasa.gov/universe/science/stars.html
http://science.hq.nasa.gov/universe/sci ... axies.html
And that gravity alone holds the universe together.

http://en.wikipedia.org/wiki/Classical_ ... d_theories
Then we discovered a force a thousand million billion billion billion times more powerful than gravity. (10^35)

http://hyperphysics.phy-astr.gsu.edu/hb ... lefor.html
Until recently we believed the space between the stars and planets was empty, a vacuum.

We now know it is teeming with charged particles.
