Content of the Universe Pie Chart (Chart)
Planck data reveals that the universe’s contents include 4.9% ordinary matter, or atoms, the building blocks of stars and planets. Dark matter comprises 26.8% of the universe. This matter, different from atoms, does not emit or absorb light. It has only been detected indirectly by its gravity. 68.3% of the universe, is composed of “dark…

The dust bunnies that built our planet – Lorin Swint Matthews (video)
Consider the spot where you’re sitting. Travel backwards in time and it might’ve been submerged at the bottom of a shallow sea, buried under miles of rock or floating through a molten landscape. But go back about 4.6 billion years, and you’d be in the middle of an enormous cloud of dust and gas orbiting…

Eye vs. camera – Michael Mauser (video)
Your eyes don’t always capture the world exactly as a video camera would. But the eyes are remarkably efficient organs, the result of hundreds of millions of years of coevolution with our brains. Michael Mauser outlines the similarities and differences between your eye and a video camera.

What are gravitational waves? – Amber L. Stuver (video)
Ted Ed video: In September 2015, scientists witnessed something never seen before: two black holes colliding. Both about 30 times as big as our Sun, they had been orbiting each other for millions of years. A fraction of a second before the crash, they sent a vibration across the universe at the speed of light…

Light seconds, light years, light centuries: How to measure extreme distances – Yuan-Sen Ting (video)
Ted Ed video:When we look at the sky, we have a flat, two-dimensional view. So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine the distance of objects several billion light years away from Earth. https://ed.ted.com/lessons/how-do-we-measure-distances-in-space-yuan-sen-ting Space, Light,…

How do we study the stars? – Yuan-Sen Ting
Ted Ed video:Our best technology can send men to the Moon and probes to the edge of our solar system, but these distances are vanishingly small compared to the size of the universe. How then can we learn about the galaxies beyond our own? Yuan-Sen Ting takes us into deep space to show how astronomers…
