In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

Light scattering techniques have emerged as a powerful set of non‐invasive optical methods for the analysis of cells and particulate matter. By measuring and interpreting the patterns of light ...

According to the studies of quantum mechanics, light can act simultaneously as a particle and a wave. However, scientists have never been able to capture light in both of its forms at the same time— ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...
