All the “normal” matter, like the stars, gas, dust, and people, is called baryonic matter, and it’s basically the tiny visible fraction of a universe that’s mostly invisible and still not fully ...

They show up as a mathematical solution in general relativity, basically as a time-reversed version of a black hole. Some ...

A multifractal spectrum called a weighted Cantor set model can describe how galaxies cluster, which is similar to other ...

Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough ...
