Gravitational waves and spacetime ripples have so much more to do with the Universe than just merging black holes. “The years of searching in the dark for a truth that one […]
With huge suites of data, we can extract plenty of signals where we know to look for them. Everything else? That’s where AI comes in. At the dawn of the 20th […]
Scientists discover unusual galaxies that raise questions about Einstein’s theory of gravity and the existence of dark matter.
Get ready for a decade of scientific revelations. Thanks to gravity waves, we have a completely new way to explore the universe.

Today, our visible Universe contains 2 trillion galaxies, each with billions of stars. But when did the very first one appear? When we look out at our Universe today, there are […]
They’re the fastest rotators of all. So how distorted are they? There are very few objects in the Universe that stand still; almost everything we know of rotates in some way. […]
You know what would make LEGO even better? A base tape that lets you build against gravity.
From millions of miles to millions of light years, there’s nothing else that leaves trails like this. When you point your telescope at the distant Universe, observing a faint, massive object […]
The latest challenger to dark matter’s throne may not be so difficult to knock off, after all. This post was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
Researchers are beginning to understand the relationship between black holes and galaxies.
What if alien life — or even intelligence — don’t look like what we’re searching for? When the original Star Trek premiered, it was revolutionary for depicting sentient, intelligent species other than humans, living […]
If it proves true, it could heal the rift between quantum mechanics and the theory of relativity.
Evolution exists and exerts itself in a different way than gravity does… because natural selection is an “algorithmic force.”
New research explains how to build different types of outposts in space.
NASA scientists are sifting through some of the last transmissions from Cassini. And what they’re finding are kittens. You read that right.
If everything goes right, astronomy will take a magnificent leap into the future. But here’s what needs to happen first. Back in 2000, NASA held their decadal survey, choosing what would […]
A new look at the intertwined lives of two of the 20th century’s greatest minds. In the years prior to World War II, physics was in an odd, post-revolutionary state. Quantum […]
But is this really a problem for the theory? Or is it physics to the rescue? Dark matter is one of the most powerful, yet one of the most controversial, ideas […]
Every week, we do a little round-up of comments from the Big Think Facebook. Here’s some of the more intriguing ones of the week.
As wonderful as the evidence that supports or invalidates a theory is, it can never truly kill the ones that don’t work out. When it comes to science, we like to […]
If it weren’t just the three space and one time dimensions, what would be different? “There is a fifth dimension, beyond that which is known to man. It is a […]
The iconic physicist warns that we’d better find another planet in the next 100 years, or humanity is screwed.
If it’s the anti-version of normal matter, could it possibly fall “up”? This article was written by Sabine Hossenfelder of Backreaction. Sabine is a theoretical physicist specialized in quantum gravity and […]
The ELT, at 39 meters in diameter, will dwarf everything that’s ever come before. “There are so many people who are arguing or fighting over issues which don’t have much relevance. […]
Why weightlessness is possible, even if there’s no place you can hide from the Universe’s longest-range force. “It was a strange lightness, a drifting feeling. Zero gravity. I understood that […]

The first stars formed almost half a billion years before we could see their light. Here’s why. At the moment of the Big Bang, the Universe was full of matter and […]
A live-blog event happened a week ago, but you can catch the entire thing anew here, right now! “We have never observed infinity in nature. Whenever you have infinities in […]
The atoms, planets, stars, and even galaxies aren’t expanding, even though space is. How come? This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity […]
