Strange X-rays point to possible ‘dark’ matter
Scientists have been looking for “dark” matter. It’s supposed to make up most of the universe — but it’s also invisible. X-rays may now point to where some of this weird stuff is.

Explainer: How heat moves
Energy moves through the universe one of three ways: conduction, convection and radiation. Only radiation can occur through empty space.

Explainer: When loud becomes dangerous
Many people don’t realize that sounds — even those of the music they love — can prove harmful when they get too loud.

Scientists Say: Wavelength
When something travels as a wave — such as light — scientists can measure it by its wavelength, the distances between the peaks.

Scientists Say: Watt
Say Watt? This is a unit used to measure the flow of energy being used.

Gravity waves detected at last!
Albert Einstein predicted gravitational waves 100 years ago. Now scientists have detected them coming from the collision of two black holes.

Explainer: What are gravitational waves?
Albert Einstein had predicted that large catastrophes, like colliding black holes, should produce tiny ripples in the fabric of space. In 2016, scientists reported finally detecting them

How to catch a gravity wave
Physicists have just announced finding gravity waves. The phenomenon was predicted a century ago by Einstein’s theory of general relativity. Here’s what it took to detect the waves.
