Progress in the foundations of physics is moving slowly. And yet it moves. Today I look at the five biggest problems in ...

(via Sabine Hossenfelder) Last year, Jonathan Oppenheim’s theory of post-quantum gravity was the only theory that made it into my Best of 2024 summary. Post-quantum gravity is one of the most ...

Sabine Hossenfelder is one of the people I regularly watch on the YouTube platform. She is a physicist but also veers into other areas such as artificial intelligence and quantum computing. For her ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Earlier this month, Google announced a brand-new quantum chip dubbed Willow. The 105-qubit chip — that’s double the qubit count of the tech giant’s preceding Sycamore chip — completed a computation in ...

Google has made an eyebrow-raising claim, saying that its new quantum chip may be tapping into parallel universes to achieve its results. The search giant recently unveiled a new quantum computer chip ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

Google's latest breakthrough in quantum computing, the Willow chip, is reigniting discussions among the scientific community about the possibility of parallel universes. Hartmut Neven, the founder and ...
