Physicist Sean Carroll explores some of the deepest mysteries in quantum mechanics: the famous double-slit experiment, wave ...

Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every time we find a new quantum technique, there's a reason it doesn't quite work ...

Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Theoretical physicists Joao Magueijo and Lee Smolin have proposed that time is not merely a backdrop against which the universe unfolds but a quantum variable that directly shapes cosmic expansion.

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth curvature of spacetime, the other the jittery statistics of particles and ...

Where did the universe come from? Where is it headed? Answering these ­questions requires that we understand physics on two vastly different scales: the cosmological, referring to the realm of galaxy ...
