Cosmologists have discovered new evidence from the early universe that suggests we are living in a giant void.

"The resulting acceleration on the object depends on the so-called area-to-mass ratio, which is greater for small and light, low-density objects." ...

Are we living in a cosmic void? New theory suggests our galaxy sits in a giant hole warping the universe's expansion.

This low-density planet has a fluffy appearance due to its unique atmospheric composition, which includes clouds of silicate sand. The findings reveal that the planet is not only an intriguing object ...

The first of these states, low-density amorphous ice, was discovered in the 1930s. It's made by depositing water vapor on very cold surfaces.

It’s hard to get x-ray images of low-density materials, such as the tissues between bones, because x-rays just pass through like sunlight through a window. But what if you need to see areas that ...
