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 ...

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...

Every now and then, it is worth pausing for a second and giving thanks to the many, ever so slightly different versions of you that exist in parallel realities. It is these alternative selves that ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...

In the deadly game Russian roulette, a player loads a gun with a single bullet, spins the cylinder to randomize the bullet’s position, and turns the potentially lethal weapon on their own self. But in ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Rather than tweaking Einstein’s theory to fit into quantum rules, they suggest flipping the script. Their model, called a “postquantum theory of classical gravity,” aims to rethink the deep link ...

A recent groundbreaking experiment in which anesthesia was administered to rats has convinced some scientists that tiny structures in the rodents’ brains are responsible for the experience of ...
