Physics has an elephant in the room and its name is complexity. A few years ago a group of researchers made the first serious attempt to quantify it – called “assembly theory” – and now the same group says their method solves one of the biggest problems in the search for alien life. Genius or nonsense? Let's take a look.

Everything in the universe, galaxies included, started out as tiny quantum fluctuations. So why isn’t a galaxy in two places at once? Physicists have long said decoherence takes care of this. Now several new papers say it doesn’t. Let’s take a look.

Guest: It’s Happening
After mathematics, AI is now coming for physics, writing papers on new particles, dark matter and the fine structure constant. OpenAI claims progress on a major physics problem, but physicists say it doesn’t matter. Maybe the real problem isn’t the AI. Let’s take a look.

Now historians have read diaries that were locked away for decades, and they tell a rather different story.

Two physicists in France say they have spotted something odd in data from the Large Hadron Collider: heavy particles that could only exist if space has an extra dimension. If they’re right, it would be one of the biggest discoveries in physics in decades. But there are some problems with their story. Let’s take a look.

For a decade, two ways of measuring how fast the universe expands have given different answers, a problem known as the “Hubble tension”. Now a group of physicists says the problem isn’t the supernovae but how we read the cosmic microwave background. The culprit, they say, is something we’ve ignored: magnetic fields from the birth of the universe. Crisis averted? Let’s take a look.

One of the biggest debates in tech at the moment is the question of whether current AI models can become conscious. Whatever “conscious” means. According to a group of biologists, current AI models are far from it – but it’s not because consciousness can only appear in biological systems. They identify which key properties an artificial system would have to fulfill to become more like the human brain and hence have a chance at developing consciousness. Let’s take a look.

Upgrade Your Shaving Experience With Henson (100 Free Blades) Nearly everything published about quantum physics in the brain is nonsense. This time a physicist in Istanbul has come up with something different, and the key move is that quantum effects don't need to last long to leave a permanent mark. No exotic new physics required, and there's a concrete way to test it. Let's take a look.
