A new gravitational model suggests dark matter may not exist. By allowing gravity to weaken more slowly at large distances, physicist Naman Kumar shows galaxy rotation curves can be explained using ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

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

Some South Chicago residents are concerned about the economic and environmental impact the 128-acre park will have on the area. The Illinois Quantum and Microelectronics Park on Chicago’s South Side ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Researchers at TU Wien have integrated quantum physics with general relativity, revealing significant departures from established models. The study was published in Physical Review D.

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum theory—our two best bets on understanding the universe on a macroscopic and ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

Gift Article 10 Remaining As a subscriber, you have 10 articles to gift each month. Gifting allows recipients to access the article for free. The University of Illinois is seeking a developer for two ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Teleportation is a reality in 2025 — well, at least for quantum computers. In February 2025, Oxford University demonstrated the teleportation of quantum data from one independent quantum processor to ...
