Dark matter has never been directly detected, but the astronomical evidence for its existence is overwhelming. Here’s what to know.
The laws of physics aren’t changing. But the Earth’s conditions are different than what they used to be, and so are hurricanes as a result.
Taught in every introductory physics class for centuries, the parabola is only an imperfect approximation for the true path of a projectile.
The “little red dots” were touted as being too massive, too early, for cosmology to explain. With new knowledge, everything adds up.
Bend it. Stretch it. Use it to conduct electricity.

The Bullet Cluster has, for nearly 20 years, been hailed as an empirical “proof” of dark matter. Can their detractors explain it away?
If you go young, blue, and massive, you top out at 50,000 K. That’s peanuts! Surprise! The biggest, most massive stars aren’t always the hottest. Although its neighbor, Messier 42, […]
The universe is only 13.8 billion years old, but we can see back 46.1 billion light-years. Here’s how the expanding universe does it.
Finding it at all was a happy accident. Examining it further may help unlock the secrets hiding within the earliest galaxies of all.
Do they have real, observable effects, or are they merely calculational tools?
Benjamin Franklin’s lightning rod saved countless lives, but some religious leaders denounced his invention.
