A physicist from Japan claims that he has found the first direct evidence for dark matter in very highly energetic gamma-ray emissions from the centre of our galaxy. Let’s have a look at the paper.

Scientists just found a massive 7,000 kilometer-long gravitational anomaly off the coast of Africa in data from a NASA satellite. The anomaly occurred from 2006 to 2008 and has now disappeared. What caused it? Let’s have a look.

I’d much rather only bring you good news, but I feel like I can’t just be quiet about this unfolding climate disaster. I no longer believe that we are able to keep the damage manageable by reducing emissions, and so all signs point to geoengineering.

"What the FUCK is wrong with Europe?"

Der Hauptgrund dafür, dass 🇪🇺 mehr und mehr in Richtung autoritärer Strukturen abdriftet, liegt für @hossenfelder.bsky.social in der extremen Trägheit des Sozialstaats, der zu langsam ist, um mit dem rasanten technologischen Fortschritt Schritt zu halten. 1/8

We don’t see the effects of quantum physics outside the submicroscopic scale. But why, exactly, is this true? According to physicists who’ve recently published a paper on that question, the theory of Quantum Darwinism can answer it. Let’s take a look.

You’ve probably heard that human industrialization is actually a mass extinction event that’s killed off hundreds of thousands of different animal species, I certainly did. But is that actually true? Let’s take a look at the numbers.

The Simulation Hypothesis is the idea that our universe is actually an algorithm being run on a mysterious supercomputer. In a recent paper, a group of physicists say they’ve disproved this theory by using Goedel’s theorem. Let’s take a look.

The 2011 Nobel Prize in physics was awarded for the discovery that the expansion of the universe is accelerating based on data from supernovae. A new analysis now looks at a larger data set & finds that the Nobel Prize winning conclusion doesn't hold up.

In a recently published paper, a group of physicists outlined a new theory which might explain why our universe contains solid matter. According to the paper, the universe was at one point filled with tiny knots made up of pure energy.

Physicists really do believe that their discipline is the basis for all other sciences because, well, it is. Recently, physicists have been applying physics to biology, using physics principles to predict how life itself evolves. Let’s take a look.
