And what might we learn as we collect new, never-before-seen data? If you took one of history’s top scientists from 100 years ago and dropped them into today’s world, what […]

It might seem puzzling, in a Universe bound by the speed of light, that this could be true. Here’s the science behind it. If you look out into the distant Universe, […]
Why are we so hung up on Pluto's planetary status? Astrophysicist Neil deGrasse Tyson urges us to get over it already!
Is gravitational repulsion a real thing? “For the first time, astronomers have outlined and named the network of galaxies that includes the Milky Way, adding a line to our cosmic address […]
It’s not appealing to authority that’s the problem; it’s the false authorities and what comes next if you accept their nonsense. “When a scientist says something, his colleagues must ask […]
All pointing toward the Standard Model plus General Relativity not being all there is. “The Universe is very, very big. It also loves a paradox. For example, it has some extremely […]
Sorry to all you ‘Flash’ fans out there; it’s not reality yet. This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and high energy […]
It’s the ‘nightmare scenario’ for some. But for Sabine Hossenfelder, it might be a dream come true. This article was authored by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
It might not be an actual supernova remnant, but thanks to 3D printing, it’s the next best thing! This article was written by Kim Kowal Arcand. Kim is the Visualization Lead […]
And the science of how we can find it. This article is written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and high energy physics. She also […]
Even most of the pros don’t know all 10. This post was contributed to Starts With A Bang by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity […]
And what it means if we don’t see gravitational waves from inflation in the next 5–10 years. “The paradigm of physics — with its interplay of data, theory and prediction — is the most powerful […]
And because of it, we can learn about quantum entanglement across a black hole’s event horizon. This article was contributed to Starts With A Bang by Sabine Hossenfelder, whose blog, Backreaction, […]
There were two periods of exponential expansion in the Universe: one today and one long ago. Are they related? “What is wild cannot be bought or sold, borrowed or copied. […]
Is it possible that our problems indicate a flaw in the theory of gravity? “I soon became convinced… that all the theorizing would be empty brain exercise and therefore a […]
If String Theory has nothing to do with reality, what are our options? “I just think too many nice things have happened in string theory for it to be all […]
Theorems are gold in math. But in physics? The Universe will surprise you. “What we need is more people who specialize in the impossible.”–Theodore Roethke Physics is one of the […]
It’s what holds the nuclei in atoms together, overcoming electric repulsion. But how does it work? “I found I could say things with color and shapes that I couldn’t say […]
The Universe is full of surprises. These are the biggest, plus what they mean. “Surprise is the greatest gift which life can grant us.” –Boris Pasternak So it is in […]
Forget nine lives; if one interpretation of quantum mechanics is right, the cat might have an infinite number of them. Observers are the necessary, but unliked, bouncers in the elegant […]
Encounters in the fourth dimension. We all have an intuitive sense of what a dimension is. There are only three perpendicular directions in which we might move, which we might […]
All things being equal, the simplest explanation is usually the best. But we don’t all agree on what “simple” means. “It is always the simple that produces the marvelous.” –Amelia […]
How an experiment high above Antarctica — Spider — sheds new light on the cosmic microwave background. Observations of the cosmic microwave background continue to capture public attention, highlighted these last few weeks in […]
How new developments in measuring the highest-energy particles and earliest signals from the Universe are teaching us what all this is. Big questions in the field of Cosmology are often […]
What it means if there’s no life anywhere else in the Universe, and what we know so far. “Men occasionally stumble over the truth, but most of them pick themselves […]
