If space is made of quantum particles, what makes it bend under the weight of a star?
For decades, physicists have been stuck on a frustrating problem: how to make Einstein’s smooth, flexible gravity fit with the jagged rules of quantum mechanics. The gap is finally starting to close, a shift captured in this 3 June 2026 feature from Quanta Magazine. Theorists already suspected that quantum particles build the rigid structure of space. To make that space bend, they are now borrowing a concept from quantum computing known as "magic." The math leads to an unexpected question: what if gravity only exists because the universe is slightly messy?
A report on how physicists are using a quantum computing concept called "magic" to introduce gravity into quantum models of the universe. Traces the shift from early models that used basic entanglement to build static space to new error-correcting codes that allow space and matter to interact. These updated codes make space flexible, giving quantum models the ability to simulate gravity.
