What really happens in the quantum world? In this conversation, physicist Sean Carroll explores some of the deepest mysteries ...

Does quantum mechanics really reflect nature in its truest form, or is it just our imprecise way of describing the weird properties of the very small? A famous test that can help answer this question ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

From the vantage point of quantum physics, the universe may in some ways be fundamentally unknowable. In quantum physics, every object, such as an electron, is matched to a mathematical formula called ...
