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 […]

What would energy without a particle to attach itself to even look like? “It is only through labor and painful effort, by grim energy and resolute courage, that we move on […]

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 […]

The laws of physics are symmetric, but the Universe isn’t. Something’s gotta give. “If antimatter and matter make contact, both are destroyed instantly. Physicists call the process ‘annihilation.” –Dan Brown When […]

And defeat for new physics. Without something spectacular, there’s no reason to build a bigger collider. “There is nothing new to be discovered in physics now. All that remains is […]

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 […]

A correlation between normal matter and the observed rotation suggests that maybe dark matter isn’t a certainty, after all. “Nothing in the standard cosmological model predicts this, and it is almost […]

What’s the difference between “point-like” and what we can actually state? “When we think about the present, we veer wildly between the belief in chance and the evidence in favour of […]

“Eureka!” is not always as powerful as “that’s what I thought!” “Reality is what kicks back when you kick it. This is just what physicists do with their particle accelerators. […]

The 750 GeV particle that the LHC thought it saw? A sham. And we all should have known. “The first principle is that you must not fool yourself, and you are […]

And what, exactly, is the significance of a tetraquark? “I found I could say things with color and shapes that I couldn’t say any other way — things I had no words […]
