In scientific theories, the Multiverse appears as a bug rather than as a feature. We should squash it.

Three of our dimensions are spatial and one is temporal, but could there be more? From any point in space, you are free to move in any direction you choose. No […]

The Big Theoretical Physics Problem At The Center Of The ‘Muon g-2’ Puzzle In early April, 2021, the experimental physics community announced an enormous victory: they had measured the muon’s magnetic […]

The mismatch between theory and experiment is anything but certain. The most exciting moments in a scientist’s life occur when you get a result that defies your expectations. Whether you’re a […]

There’s a lot to get rid of if we want to get only our Universe out of String Theory. A lot of people, when they learn about String Theory for the […]

It might not feel that way, but a 95% dark Universe really is the best game in town. No matter how much we might try and hide it, there’s an enormous […]

Often viewed as a theoretical, calculational tool only, the Lamb Shift proved their existence. If you spend enough time listening to theoretical physicists, it starts to sound like there are […]

We just found a system that we can’t explain. Here’s what’s going on. One of the most fascinating facts about the Universe is that there’s so much of it out there. […]

Could this finally be the clue we’ve hoped for in uncovering the truth about dark matter? In the physical sciences, theory and observation are supposed to work hand-in-hand. Theorists work out […]

Even physicists sometimes fall for these. For centuries, the laws of physics seemed completely deterministic. If you knew where every particle was, how fast it was moving, and what the forces […]

Just because an idea is fashionable doesn’t mean it’s relevant for our Universe. One of the greatest unsolved puzzles in all of science is dark energy. The Universe isn’t just […]

It’s not a question we know enough to know the answer to, but to dismiss the possibility is scientifically baseless. There’s one question that most of us ask at some […]

A fascinating mathematical structure exists that goes well beyond our common experience. Could it revolutionize physics? Perhaps the most remarkable fact about the Universe is that every particle within it — at […]

As soon as you start thinking about energy and gravity, you’ll realize the need to go beyond it. When it comes to a science like physics, theoretical expectations must always be […]

The quest for a quantum theory of gravity is the holy grail of physics. Here’s why it’s murkier than anyone expected. If you want to fully describe how the Universe […]

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 […]

There are only two perfect numbers that fit on the calendar: 6 and 28, making June 28th Perfect Number Day. Find out what makes a number perfect, and why they matter. […]

There’s no such thing as a theory that’s too beautiful to be wrong, if it doesn’t agree with experiment. The history of physics is filled with great ideas that you’ve […]

We see matter, but not antimatter, in our Universe. Could black holes be the answer? One of the greatest cosmic puzzles in our entire Universe is why there’s so much more […]

Ever hear of Hawking radiation? Or the black hole information paradox? Time to get your fix! In memory of Stephen Hawking’s life, I’ve decided to share the physics behind his greatest […]

What do our future missions in physics, astronomy, astrophysics and more hold? If you went back in time just 30 years, the world as we it was a completely different place. […]

If the LHC can’t produce new fundamental particles, the collisions coming from it still a chance to teach us something incredible. “It was quite the most incredible event that has […]

If you heard about time crystals, be aware that they do exist. But learn what they mean. “Every particular in nature, a leaf, a drop, a crystal, a moment of time […]

Your theory predicts something novel? How nice. But no one will pay you any mind unless you test it. “He who loves practice without theory is like the sailor who boards […]

Just because we know it’s real doesn’t mean it’s easy to create in a lab. “For me the best answer is not in words but in measurements.” –Elena Aprile Atoms, molecules, […]

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 […]
