The Mayas: the civilization that was technologically ahead of its time.
The Mayans had such advanced knowledge of astronomy that they knew that in the center of our galaxy there is a black hole with a diameter of one light year.
The Mayas were a civilization that existed for more than 2 thousand years between the years 250 and 900 of our era. It was a population between 15 and 20 million people in the now city of Yucatán in Mexico, and extended as far south as Costa Rica and Guatemala.
The archaeological evidence found suggests that the Maya were one of the first civilizations to develop a written language, use modern mathematical methods, and build huge astronomical observatories. All this when in Europe they were going through the dark ages.
The Mayans were a civilization that enjoyed having an Astronomy, advanced architecture for its time. The Mayans measure time and that was magical for them, they recorded Venus and the changes of the moon and eclipses.
The scientific advance of the Mayans was so great that they knew that in the center of our galaxy there is a black hole with a diameter of one light year and that it is a place without a star, and they called this phenomenon the great fissure . This astronomical knowledge was understood by ancient Mayan astronomers during that time.
The Mayas believed that their astronomical knowledge came from their gods and that their gods were in the stars. According to some experts, it is very possible that these gods could have been aliens who somehow had connections with the Mayans.
According to the Mayans, this astronomical knowledge was not something that they discovered, but rather it was a gift that was given to them by the gods, it is not something material, but it is knowledge and it is like a kind of currency with which it is bought in the universe.
