Few scientific ideas have leapt from philosophy seminars to dinner-table debates as quickly as the claim that our universe might be an artificial construct. The simulation hypothesis promises a ...

When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift—all within millionths of a ...

A physicist has mounted one of the most detailed technical challenges yet against the idea that our universe is a computer simulation, arguing that the energy required to run such a program would ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Last November, a group of physicists claimed they’d simulated a ...

A research team at the Jülich Supercomputing Center, together with experts from NVIDIA, has set a new record in quantum simulation: for the first time, a universal quantum computer with 50 qubits has ...

Melvin M. Vopson does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond ...

Scientists have developed a new computer model that simulates how moon dust behaves in lunar gravity. They hope it will help future robotic moon explorers to do their job more safely. When you ...
