In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...

However, to measure spacetime fluctuations with an interferometer, we need to know where—i.e. at what frequency—to look, and what the signal will look like. With our framework, we can now predict this ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting “spacetime fluctuations” - tiny, random distortions in the fabric of spacetime that ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

Eric and Wendy Schmidt are backing a start-up-like approach to building a giant space telescope and powerful ground observatories. By Kenneth Chang Kenneth Chang reported on the unveiling of Schmidt ...

A SpaceX Falcon 9 rocket is scheduled to launch from Southern California on Sunday, Jan. 11, 2026. This launch will double as a mission to deploy NASA's Pandora satellite, as well as a rideshare ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

Cosmic strings are artifacts of what the universe looked like in the moments before it rapidly changed from a high-energy to low-energy environment—the Big Bang. Today, scientists believe cosmic ...
