One of the biggest challenges in modern physics is uniting quantum mechanics and general relativity. A new experiment may ...

In 1919, a total solar eclipse allowed scientists to confirm Einstein’s theory of general relativity by observing how the sun’s gravity bent starlight. This discovery revolutionized physics and made ...

A new study published in the journal PRX Quantum demonstrates how a network of quantum computers employing optical clocks can ...

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics.

Scientists propose using quantum-entangled clocks to test how gravity affects quantum mechanics in curved spacetime.

Time, as we experience it on Earth, may not be as constant as we imagine. According to Einstein’s theory of general relativity, time is not uniform across the universe; it’s actually affected by both ...

The theorists predict that the beginning of the end will be in about 10 billion years — less than the present age of the universe.

The merger resulted in a combined black hole 225 times our sun’s mass, and challenges current astrophysical models of black ...

Using the Hubble Space Telescope (HST), astronomers have observed a nearby ultra-diffuse galaxy designated F8D1. The new ...

True V-8 engine performance comes from ensuring airflow flow in, out, and through the combustion chamber is the best it can ...

Most of the universe is made up of hydrogen and helium atoms, which came into being after the Big Bang cooled down a little. Heavier atoms are formed during high-energy collisions in stars.
