is it time?

Some have come up with theories regarding Giza and how it is a warning about future catastrophes or the end of the world. Is there any truth to 2012 or similar theories? I took a look at what the sky looks like from the sothernest pyramid of Egypt – not in the past but now. It seems that the Giza pyramid plan encodes this date via the maximum altitude of the stars Sirius and Alnitak. Are we actually now – not in 3 years - at the end of days or is it simply the time we have a visit? I just want to point out that we have a perfect match for both cases – down to one hundredth of a degree based on Petrie’s survey. Also if we move to a slightly different latitude – let’s say the Hawara pyramid – see Labyrinth , then we see that when one star matches – the other doesn’t match exactly. So it seems that this is the (only) observation point and it also seems that the epoch is NOW! Can anybody confirm this? We might not have much time. I used Starry Night Pro Plus 6.
