Are we living in a simulation? This experiment could tell us | New Scientist
Thomas Anderson – otherwise known as Neo – is walking up a flight of stairs when he sees a black cat shake itself and walk past a doorway. Then the moment seems to replay before his eyes. Just a touch of déjà vu, he thinks. But no, his companions insist: he is living inside a computer program and he has just witnessed a glitch.
Quantum experiment finally settles a century-old row between Einstein and Bohr | New Scientist

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries of quantum physics: is light really a wave, a particle or a complex mixture of the two?
Introducing InnovaTED! An initiative to amplify the ideas and voices of students and educators
Xixi Wang
What if students and educators could share their best ideas with each other, their communities, and the world?
We’re thrilled to introduce InnovaTED — a new initiative from TED-Ed and TEDx designed to amplify the voices of students and educators around the world! Combining TED-Ed’s public speaking expertise with TEDx’s ability to activate local communities, InnovaTED is a global platform that elevates the voices and ideas of students and educators.
Formula 1: What is next for Red Bull's Yuki Tsunoda?
Yuki Tsunoda has been dropped by Red Bull as a driver for the 2026 season.
The Japanese driver will not drive for them or their sister team, Racing Bulls, next year.

Black hole entropy hints at a surprising truth about our universe | New Scientist
Imagine you’re standing in front of a closed door. Behind it is a teenager’s bedroom, and your task is to rate how messy it is on a scale of 1 to 10. But here’s the twist: you can’t open the door – and you don’t even know what kind of stuff might be inside.
Physicists have worked out a universal law for how objects shatter | New Scientist

A dropped plate, a smashed sugar cube and a broken drinking glass all seem to follow the same law of physics when it comes to how many fragments of a given size they will shatter into.
We might have just seen the first hints of dark matter | New Scientist

An unexplained glow that appears to emanate throughout the Milky Way’s outer regions could be our first hint of what dark matter is made of, but astronomers say it is too early to know for sure.
We may need a fourth law of thermodynamics for living systems | New Scientist

The physics of thermodynamics, which involves quantities like heat and entropy, offers well-established tools for determining how far from equilibrium an idealised system of particles is. But when it comes to life, with its complex interconnected cells, it’s not clear that our current array of thermodynamical laws is enough – and a set of experiments involving human cells might be a first step towards creating a new one.
A new understanding of causality could fix quantum theory’s fatal flaw | New Scientist
The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the world – or at least, it is for the world we see, governed by classical physics.
