The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

Some celestial bodies are so cold that methane freezes; others are so hot that nuclear reactions occur. And then there’s Earth, with a benign temperature hovering in the narrow range between freezing ...

The accelerating expansion of the Universe might not be just an unexplained phenomenon — according to a new proposal by theoretical physicists, it could be a fundamental feature woven into the very ...

Physicists have proposed a new model of space-time based on string theory to explain dark energy. Their hypothesis suggests that, at extremely small scales, space and time behave differently from how ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my ...

But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial splash, some ...

Tue, April 8, 2025 at 6:00 PM UTC The centuries-long Copernican journey of slowly displacing humans from the center of everything has provided our species with an unprecedented understanding of our ...

Last month, the Dark Energy Spectroscopic Instrument (DESI) collective reported that dark energy is evolving—specifically weakening—and it could help provide the first observational evidence of string ...

Gauge theory and string theory represent two foundational pillars in contemporary theoretical physics, offering profound insights into the nature of fundamental interactions and the structure of the ...

Philosopher Bertrand Russell believed that the way we understand our world fundamentally shapes the way that we live our lives. Thus, an anarchist lives a very different sort of life than, say, an ...

of its present age and the presence of the galaxy string defies existing models, which can not explain how a string this big could have formed so long ago. This is the first time astronomers have been ...
