That means its density is about 0.059 grams per cubic centimeter. By comparison, cotton candy’s density is about 0.05 grams per cubic centimeter and Earth’s is 5.51 grams per cubic centimeter.

From the exploration of both standard nuclei and alpha matter, it is clear that both types of nuclear matter could explain the density seen in CUDOs such as asteroid-33 Polyhymnia. Asteroid-33 ...

Density can be measured in lots of different units, but the most commonly used units are grams per cubic centimetre (g/cm³) and kilograms per cubic metre (kg/m³).

Carbon nanotubes offer comparable conductivity at 1.7 grams per cubic centimeter, providing a potential for reducing motor weight by more than 80%. The main challenge has been contamination.

Ask bacteria where they’d like to live, and they’ll answer: a kitchen sponge, please. Sponges are microbe paradises, capable of housing 54 billion bacteria per cubic centimeter. In addition to ...
