The latest gravitational wave data from LIGO and Virgo finally shows us the truth: there are no "gaps" in the masses of black holes.
Based on the atoms that they're made out of, the innermost planet should always be the densest. Here's why Earth beats Mercury, hands down.
Although many dinosaurs never left the ground, they still possessed the basic structural framework for flight.

How the search for alien life is taking place right here in our own Solar System. If you want to understand the origin of life in the Universe, you have three […]
More energy means more potential for discovery, but we’re topped out. If your goal is to discover something completely novel, you have to look in a way that no one else […]
Whatever’s lurking out there, it isn’t all, or even mostly, normal matter. When it comes to the Universe, it’s only natural to wonder what, exactly, it is that makes everything up. […]

Delaying or refusing vaccines for non-medical reasons is literally a killer choice. When it comes to issues at the intersection of science and society, there are all sorts of things that […]
Hubble, our greatest space-based observatory today, is just the beginning. The Hubble Space Telescope has been astronomy’s most revolutionary observatory in history. The stars and galaxies we see today didn’t […]
Galaxies can have regions both hotter and colder than the background radiation of the Universe. When we talk about the depths of space, we get this picture in our heads […]
When you mix science with speculation, you get speculation. But the underlying science is still real. Whenever you hear the phrase, “it’s just a theory,” it should trigger alarm bells in […]
