Physicists long believed time was a basic feature of the universe. But it may just emerge from cosmic information.

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...

Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Time may not be a fundamental element of the universe but rather an illusion emerging from quantum entanglement, a new study suggests. Time is a thorny problem for physicists; its inconsistent ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

The quantum world operates by different rules than the classical one we buzz around in, allowing the fantastical to the bizarrely normal. Physicists have described using quantum entanglement to ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...
