Three years ago, I described a crisis raging full force around the subject of the actual age of dinosaur remains, thereby equally implying a crisis in our historical understanding; namely, just when did the dinosaurs actually perish?
Was it really 65 million or even 200 million years ago, or was it within the effective range of carbon dating; i.e., 50,000 years, 25,000 years ago, or less? On the Pacific coast of Guatemala, not far from Santa Lucia Cotzumalguapa, the clearing work done in 1860 brought some magnificent Mayan steles to light (today, they are known as the Bilbao monuments).
Note: To put Nawarla Gabarnmang into context, the oldest art created by modern humans includes the Blombos Cave engravings (70,000 BCE) and the Diepkloof Eggshell Engravings (60,000 BCE) in South Africa, and the El Castillo Cave paintings (39,000 BCE) in Spain.
For more, see: Prehistoric Art Timeline (from 2.5 million BCE).
For years, scientists have debated whether heavy inland snowfall on the vast East Antarctic Ice Sheet--Earth's largest--balances out the rapid melting in West Antarctica. Self-proclaimed 'space nation' Asgardia will launch a satellite later this year to test the concept of long-term data storage in orbit around the Earth.
Given enough snowfall, the continent might not yet be contributing to a sea level rise. signal from 1977--long thought by some to be a sign of extraterrestrial life--was in fact generated by a passing comet. This potentially opens the door to off-planet data and tax havens, according to filings obtained by Motherboard, and represents an important step towards the group's proclaimed goal of starting a private nation in space.
Stonehenge is a massive stone monument located on a chalky plain north of the modern-day city of Salisbury, England.
Research shows that the site has continuously evolved over a period of about 10,000 years.
It’s unknown how people in antiquity moved them that far.
Scientists have raised the possibility that during the last ice age glaciers carried these bluestones closer to the Stonehenge area and the monument’s makers didn’t have to move them all the way from Wales.
The civilization of Ancient Egypt occurred in a past so remote that today it seems mystical.
The pyramids and other temples, with their hieroglyphics depicting a flourishing civilization, have a mysterious, almost magical appeal.
The oldest archeological layers at the site are still being investigated, and further finds of even older prehistoric art are possible.
