How can you maximize the amount of love and happiness in your life? One of history’s greatest scientists found the answer: with math.
Unexpected images of galaxies from the James Webb Space Telescope do not disprove the Big Bang. There are other likelier explanations.
It has no moving parts and could allow us to tap into renewable energy year round.
The stars, planets, and many moons are extremely round. Why don’t they take other shapes?
Astronomers find a third type of supernova and explain a mystery from 1054 AD.
There are many theories of gravity out there, and many interpretations of wide binary star data. What have we really learned from it all?
The evidence that the Universe is expanding is overwhelming. But how? By stretching the existing space, or by creating new space itself?
There’s an extra source of massive “stuff” in our Universe beyond what gravitation and normal matter can explain. Could light be the answer?
Yes, the magnetosphere is weakening. It does that from time to time.
His grandfather, a member of Oppenheimer’s atomic bomb team, foresaw the potential of nuclear energy to power cities — not destroy them.
With LEDs bringing brighter nighttime lighting than ever before, and thousands of new satellites polluting the skies, astronomy needs help.
You would think that with all our technology, like the James Webb Space Telescope, we would know how big the Universe is. But we don’t.
Our own galaxy, the Milky Way, is both completely normal and absolutely remarkable in a number of ways. Here’s the story of our cosmic home.
Michael Faraday’s 1834 law of induction was the key experiment behind the eventual discovery of relativity. Einstein admitted it himself.
A clock, designed and built in Europe, ran hopelessly at the wrong rate when brought to America. The physics of gravity explains why.
Online Shinto communities have existed since the birth of the internet as we know it.
Everything we observe beyond our Local Group is speeding away from us, omnidirectionally. If the Universe is expanding, where is the center?
Volcanic activity caused the end-Triassic mass extinction 200 million years ago. The dinosaurs survived and rose to dominance.
By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.
60% of all potentially dangerous asteroids remain undetected.
There’s a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.
In terms of the planets we’ve discovered, super-Earths are by far the most common. What does that mean for the Universe?
An effect called the “urban heat island” means that temperatures are often 10 degrees higher in cities, according to NASA.
Due to a crust of carbon, the absence of oxygen, and constant bombardment from meteorites, the planet Mercury may be littered with diamonds.
When Cameroon’s Lakes Monoun and Nyos exploded, they released clouds of carbon dioxide that suffocated everything in its wake.
The meaning of the cryptic text has eluded scholars for centuries. Their latest efforts include computational analyses seeking new insights into the medieval enigma.
From the Big Bang to black holes, singularities are hard to avoid. The math definitely predicts them, but are they truly, physically real?
The acceptance of death is deeply embedded in our culture; it’s time to overthrow that idea.
