Coordinates of the Giza Pyramid and Speed of light Mystery still unsolved!

It seems that many mysteries surrounding the great pyramid in Giza will continue to go unsolved as experts try to uncover the facts

STRANGE DISCOVERY SHOWS THAT THE COORDINATES OF GIZA'S GREAT PYRAMID ARE THE SAME AS THE SPEED OF LIGHT 

Measured in a vacuum,The speed that light can travel at 299, 792, 458 m/s which is approximately 300,000,000 m/s.This matches very closely with the global positioning satellite coordinates for the great pyramid in Giza, 29.9792458°N.Questions have been raised casting doubts over whether the ancient Egyptians intended these mathematical relations to occur or whether they are merely coincidences. Units such as meters per second and kilograms are modern units that ancient Egypt would not have understood so it would have been difficult for them to make the required calculations 

This is one in a series of mathematical links that have been discovered between the ancient Egyptian constructions and certain areas of science and math.One of the most fundamental mathematical features of the pyramid is that its base shows the relationship between pi and phi.
In a seeming tribute to the sun from the Egyptians, twice the perimeter of the base of the pyramid multiplied by one hundred million gives a figure that is equal to the suns constant radius. 
Does it mean that the ancient Egyptian civilization was advanced enough to have an understanding of these modern units as well as concepts such as how light will behave differently when observed in a vacuum?
