This is a rare educational Web site in its ability to get us started in studying the fundamental elements in the Universe.

The chart is humbly called "History of the Universe" and contains much information in a very helpful graphic drawing.

It also illustrates the Theological point I have been making about the first Creation story in Genesis myBlog. Among all ancient religions Judaism is unique in the way personal God creates everything through words and sovereignly starts creation with light.

The first Words of Creation are Let there be light!
ויאמר אלהים יהי אור ויהי־אור
Gen 1:3

The chart shows that according to our current scientific understanding immediately after the Big Bang there are photons. Also visible light consists of photons, fundamental particles with no mass and speed of light in a vacuum. The study of light and electromagnetism with it led humanity at the end of 19th century to the track of theorizing and experimental research that has expanded our understanding of the Cosmos a bit better. 

Thanks to the intensive research today we have much more light upon what God of Israel has done!
