    The study of the Algol, made by a research group of the University of Helsinki, Finland, has received both scientific and public attention. The period of the brightness variation of this eclipsing binary star has been connected to good prognoses three millennia ago. This result has raised a lot of discussion and the news has spread widely in the Internet.

    The Egyptian papyrus Cairo 86637 calendar is probably the oldest preserved historical document of bare eye observations of a variable star. Each day of one Egyptian year was divided into three parts in this calendar. A good or a bad prognosis was assigned for these parts of a day.​
    -The texts regarding the prognoses are connected to mythological and astronomical events, says Master of Science Sebastian Porceddu.
    A modern period analysis revealed that two statistically significant periods of 29.6 and 2.850 days have been recorded into the good prognoses. The former is clearly the period of the Moon. The second period differs slightly from the period Algol. In this eclipsing binary, the dimmer star partially covers the brighter star with a period of 2.867 days.
    -We can explain why the period of Algol has increased by about 0.017 days, says Lauri Jetsu. The period increase during the past three millennia could have been caused by the observed mass transfer between the two members of this binary. In fact, this would be the first observation that confirms the period increase of Algol and it also gives an estimate of the mass transfer rate.
    The ancient Egyptians have made accurate measurements that provide useful constraints for modern astronomers.
    -It seems that the first observation of a variable star was made 3000 years earlier than was previously thought, says Lauri Jetsu. However, I want to emphasize that our research has only been sent to a scientific journal about two weeks ago. This type of results can raise a lot of controversy before they are accepted.

    They still won't recognize how old Kemet actually is.. even this 3000 years number just means its the earliest they have found in the graves they looted. But it's highly unlikely that that Cairo Calendar is the first time they discovered that information. We're talking about knowledge passed down over 10s of thousands of years..

    I've heard anywhere from 15,000 to 25,000 years old. Like you said they NEVER want us to know the truth.

    We have no birth record and they know this. This is why they had to create one for us after being kidnapped and brought to these shores. That's why as children in school they used to constantly repeat to us "you were un-civilized when we found you" - "you were cannibals when we found you" - "you were swinging from trees and had no language when we found you" - "you were butt naked in the jungles living a savage life when we found you".

    You can substitute the word "born" for the word 'found' because in this context that is what they actually mean.

    Our ancestors mapped out the 'heavens' eons before someone named tesla 'invented' the scope.
