Ancient Cities: Chichen Itza

Of the three Mayan cities we were to visit over the next two weeks, Chichen Itza was the most desirable. For us the iconic temple was a figurehead for Mayan civilisation. Based in Mexico’s Yucatan province, the UNESCO World Heritage site is one of the more popular ancient ruins, with over a million people visiting the thousand-year old city every year.

However, despite our high-expectations, standing in-front of El Castillo at Chichen Itza had us surprisingly unfulfilled. A few feet away was part of an ancient major city, a famous landmark of the Mayan empire and an overrated tourist attraction.

Populatii de stele in Calea Lactee

In prezent, se crede ca exista doua sau trei populatii de stele in Calea Lactee. Discul subtire si nimbul stelar corespund populatiilor I si II ale lui Baade. Existenta unei populatii de disc gros se afla inca in dezbatere (care ar putea corespunde cu discurile groase observate in unele galaxii de disc). Discul subtire al Caii Lactee a sustinut formarea continua de stele noi. In consecinta, discul subtire contine stele cu o gama larga de varste, iar acesta ar putea fi impartit intr-o serie de subpopulatii de varste diferite. Populatia din bratele spirale este cea mai tanara din disc – aceasta pare sa urmareasca modelul spirala al Caii Lactee. Aceasta populatie este concentrata foarte aproape de planul de disc. Obiectele reprezentative includ nori HI si moleculari, regiuni HII, protostele, stele de tipurile O si B, supergigante si clasicele Cefeide. Metalicitatea acestei populatii este ceva mai ridicata decat cea a soarelui nostru.

Google Earth locates 'lost' Egyptian pyramid

LONDON: Google Earth satellite imagery survey may have revealed two possible pyramid complexes in Egypt.

Satellite archaeology researcher Angela Micol of Maiden, NC said that the complexes were located about 90 miles apart, and contained unusual grouping of mounds with intriguing features and orientations.

One site located in Upper Egypt, just 12 miles from the city of Abu Sidhum along the Nile, features four mounds each with a larger, triangular-shaped plateau.

Ce a fost inainte de Big Bang? Exista universuri paralele?

Huge Everett III, in 1954, afirma ca exista universuri paralele ca al nostru, toate fiind legate de el. In toate aceste universuri lucrurile se petrec diferit de al nostru. De exemplu, intr-unul oamenii au disparut deja, in altul razboaiele au finaluri diferite, specii disparute in universul nostru au evoluat diferit in alte universuri. Dar toate ,vedem, sunt legate, doar evenimentele se petrec diferit.
