For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

It was 1905, and Albert Einstein had just turned theoretical physics on its head by publishing a paper on what later became known as special relativity. This showed that space and time could not be ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Astronomers have identified the birth of a magnetar, a hyper-magnetized neutron star, by detecting a subtle warping of ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion ...

For years, astronomers have wondered why real-life versions of Tatooine are so rare. With thousands of confirmed exoplanets and countless binary star systems in our galaxy, planets orbiting two suns ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. These distortions travel far out into the universe, but by the time they reach Earth, they have ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...
