What’s the average density of the universe? One look out at the night sky will confirm that space isn’t a dense place — but still, its actual density could affect everything from the way it’s shaped ...

A common question arises: can density be determined using the free space measured on a gas adsorption analyzer, rather than a device specifically designed for density measurement? This article ...

Researchers are developing a new technique to help visualize the complex internal layering and anomalous structures inside planetary bodies, including the Moon. Credit: NGC 54/Wikimedia, CC BY-SA 4.0 ...

Measuring density is crucial in manufacturing many of today’s products. Being able to characterize the structure and quality of solid materials quickly and efficiently can not only help guide ...
