An amazing video that summarizes the evolution of the Earth over four billion years in just four minutes.



About 4.5 billion years ago a mass of molten rock began to form in the Solar System, which eventually evolved into today’s Earth.

David A. Roberts, artist and computer scientist, created the evolutionary history of the planet in a captivating video that puts billions of years of transformations into a four-minute simulation.

The epic story begins with an extremely hot protoplanet full of craters still forming in a stable world.

The video moves toward a flat view of the Earth, showing that tectonic plates began to form about 3 billion years ago.

Advancing the evolutionary timeline, Roberts shows viewers colorful features that represent the waters flowing from the planet and the continents that rise above the surface.

At the end of the video are bright lights coming from continents around the world, indicating that the world that was once burning is now inhabited by humans.

Roberts shared in a blog post: “Concluding the introduction to early Earth, the rate decreases to a cycle between day and night, and the terrain becomes stationary as tectonic movements become imperceptible. night reveals unprecedented patterns of light as humanity begins to colonize. the surface of the planet. “

Roberts created a captivating simulation of the GLSL parts shader, which is part of the OpenGL graphical programming language.

The crust was unstable, bombarded by asteroids and comets, giving way to intense heat that lasted millions of years.

Then, about two or three billion years ago, tectonic plates began to form one after the other.

A 2015 study suggests that a large melted mantle plume may have emerged from the depths of the planet, gathering beneath the surface and weakening the solid crust, or lithosphere, above.

This weak point would have spread over time as more material from the deep mantle had accumulated and would have created a rupture that would then grow to create the boundary of the tectonic plates.

“The simulation randomly generates seed locations for the plates, with an initial speed. The plates grow in size over time using a simple generation model, which randomly selects adjacent points and adds them to a plate if still are not assigned to another “. Roberts shared a post.

The next part of the video shows the composition of flowing water and the continents of a more stable planet.

The oceans began to form about 3.8 billion years ago, when gases such as hydrogen sulfide and methane in the atmosphere cooled and turned into water that condensed into rain that filled the oceans. basins we now know as Earth’s ocean, according to the National Oceanic and Atmospheric Administration (NOAA).

As the water drained into the large cavities of the Earth’s surface, the primordial ocean emerged and gravitational forces prevented the water from leaving the planet.

After water flowed on Earth, the continents began to emerge at the same time, which scientists say was due to the onset of plate tectonics. Pangea, a supercontinent, existed about 300 million years ago and began to split into pieces that formed the continents we know today.

Robert also captured patterns of the Earth’s orbiting atmospheric climate that alter the topography and seasons of the planet.

“Climate affects the distribution of life on a planet,” Roberts said.

As the seasons change, herbivores migrate to areas with enough vegetation to maintain them.

Towards the end of the Roberts simulation, the concepts that humans had taken about the world became clear.

The arid terrain once shone with bright lights indicating a technologically advanced civilization that used fossil fuels to pollute the planet.

“The final section aims to illustrate a possible future, although it may be unlikely,” Roberts told Motherboard.
