Both effects could be responsible for a redshift. But only one makes sense for our Universe. In physics, like in life, there are often multiple solutions to a problem that […]

Big Think speaks with the American who’s spent the most time in space, astronaut Peggy Whitson, looking back on what she learned during life in orbit.
Stephen Hawking had pinned his hopes on ‘M-theory’ to fully explain the universe – here’s what it is
During the second string revolution, in 1995, physicists proposed that the five consistent string theories are actually only different faces of a unique theory.
Here are four separate ways you can prove it, even 50 years after-the-fact. 50 years ago, on July 20, 1969, humanity took our first footsteps on the surface of another […]
You’ve probably seen it hanging around. But how did it get there? And can we live there?
Scientific discovery often happens when you least expect it. But no one could’ve expected this. Imagine that you’re a scientist, going out on a limb to design and build an experiment […]
What should a black hole look like? Our theoretical predictions are about to meet our first observations. In science, there’s no moment more exciting than when you get to confront […]
How fast is the Universe expanding? The results might be pointing to something incredible. If you want to know how something in the Universe works, all you need to do […]
NGC 1052-DF2 was said to ‘defy theory,’ incorrectly, by many. Here’s what our current theories actually predict. Last week, astronomers announced the discovery of NGC 1052-DF2: a galaxy without dark matter. […]
There have been a lot of public advocates from the “no dark matter” camp, getting lots of popular attention. But the Universe still needs dark matter. Here’s why. If you took […]
How did Michael Jackson accomplish the famous antigravity tilt? Three neurosurgeons (and MJ fans) dissect the dynamics.
The planet has had life on it, in some form or another, for nearly as long as Earth has existed. If you came to our Solar System right after it formed, […]
Never draw a conclusion, no matter how ‘obvious,’ without doing the experiment first. We all love our most cherished ideas about how the world and the Universe works. Our conception […]
This asteroid is feeling itself, clearly.
Aura will attempt to become a frequent flyer’s go-to airline.
Yes, life exists in our Universe. No, that statement doesn’t equal science. Imagine you’ve encountered a natural phenomenon you want to understand better, but don’t have the tools to do so. […]
If dark matter doesn’t interact with normal matter or light, how can it be heated up? One of the great cosmic mysteries of our time is the presence and existence of […]
Recent books that are sure to add to your intelligence.
The Big Bang happened everywhere at once, but stars are a different story. The Universe, back at its inception, was almost perfectly identical everywhere. It was the same high temperature […]
An Oxford physicist tries to cast doubt on dark energy, but the data says otherwise. It was a mere 20 years ago that our picture of the Universe got a […]
Measuring quantum gravity has proven extremely challenging, stymying some of the greatest minds in physics for generations.
Physicists prove a core part of the theory of general relativity by using the whole Earth and the most precise clocks ever.
Wormholes might very well be a key feature to our cosmos.
If you thought LIGO’s recent discoveries were profound and unusual, wait until you meet OJ 287. Recently, LIGO has revolutionized our knowledge of the Universe by discovering merging black holes. The […]
With every second that goes by, tens of thousands of star disappear from our reach. And it’s getting worse. It’s been nearly a century since scientists first theorized that the Universe […]
Some games are just for fun, others are for thought provoking statements on life, the universe, and everything.
One of the most popular viral videos about space is dead wrong. But it gives us a chance to learn something incredible. There are a lot of moving parts to […]
Shortly after the Big Bang, the Universe became completely dark. The first stars, when they ignited, changed everything. For perhaps 100 million years, the Universe was devoid of stars. The […]
Spirituality plays a different ballgame than science, so the language used in either of them doesn’t often match up to the other side. This, says religious teacher Rob Bell, creates a lot of conflicts.

This is what we’ve learned from first object ever discovered to enter our Solar System from interstellar space. Billions of years ago, our Solar System was an extraordinarily different place […]
