Or could a few of them, somehow, have survived that mass extinction event – with their descendants living even today?It is exciting to imagine that gigantic dinosaurs are still rumbling and lumbering around in some remote part of the world. But no evidence of this exists. There are no cousins of Tyrannosaurus rex stomping through the vast woods of Siberia, no Apatosaurus ambling through the Congo rain ...read more

The Altar StoneThe implications are that the Altar Stone had speci ...read more
We’re interested in the moon because it’s close enough to Earth to allow us to practice setting up a base camp in preparation for Mars. In fact, Artemis III will send the first crewed spacecraft to the moon’s South Pole to set up camp by 2034.And while there’s still a lot that we don’t know about living on the moon, we do know a little something about its weather forecast, says Jason Steffen, a professor of physics and astronomy at the University of Nevada, Las Vegas. “There’s not ...read more
