The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

Gravitational waves are ripples in spacetime predicted by Einstein and first detected by LIGO in 2015, confirming black hole ...

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

“For the last 20 years, people believed that the cosmological constant is positive, and the universe will expand forever,” says Tye, a professor emeritus at Cornell. A positive constant acts like a ...

OpenAI's GPT-5.2 has derived a new formula for gluon interactions, overturning assumptions of zero amplitude and advancing theoretical physics.

This study explores a groundbreaking theoretical method to neutralize high-level radioactive waste using lead oxide (PbO) ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

Now, according to a new study published in The Astrophysical Journal, there could be a pulsar at the center of our Milky Way—and it could open a new chapter in physics. Researchers from Columbia ...
