The Perfect Alignment

The Orion-theory that the alignment and placement of the pyramids of Giza is widely known, though much discredited.

Whilst reading up on the theory, i came across this, alternate theory to the alignment and layout of the pyramids of the Giza plateau.

Primarily they focused on something much closer than the Orion constellation, rather they set reflect the inner planets of our solar system: Mercury, Venus, Earth, and Mars.

Twilight Zones

This chart shows the relationship between the angular elevation of the sun relative to the horizon and levels of twilight. The values are for the 24 hours between 1pm BST 12th August 2010 and 1pm BST 13th August 2010, and for the location Brighton in East Sussex (50.8° N 0.1° W). In equatorial regions, night and day breaks very much more quickly. In Brighton on this late summer day, sunset to full darkness took 2 hours and 22 minutes. By comparison, in Singapore (near the equator) the process took 1 hour 11 minutes.
