The closest technological species to us in the Milky Way galaxy could be 33,000 light years away and their civilization would have to be at least 280,000 years, and possibly millions of years, old if ...

Rocks in Australia preserve evidence that plates in Earth’s crust were moving 3.5 billion years ago, a finding that pushes back the beginnings of plate tectonics by hundreds of millions of years.

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

On Earth, the land moves. Over millions of years, continents shift and the entire surface of the planet reshapes itself. The driver of all this is plate tectonics: Earth’s surface is divided into ...

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants can ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...

President-elect Donald J. Trump is a transformative figure in contemporary American politics. Despite being impeached twice, indicted and convicted, he has been elected to the presidency for a second ...
