Astronomers have captured the clearest picture yet of how massive stars are born, revealing a dramatic interplay between ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

You may have seen videos of astronauts jumping on the moon. Their movements appear bouncier and lighter than how we move on Earth, and this is thanks to gravity. Gravity is "the force by which a ...

As they whirl around in low-Earth orbit, satellite configurations are far more sensitive to changes in Earth's gravity field ...

Keeping an orbiting satellite in the proper attitude is no mean trick. But there are times when antennas and cameras have to be kept pointing continually at the earth if they are to work effectively, ...

Dark energy could have an accomplice that helps it slow the growth of large cosmic structures, such as vast superclusters made up of clusters of galaxies. A new analysis of astronomical data suggests ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. When you purchase through links on our site, we may earn ...

Albert Einstein’s name is synonymous with “genius,” and his wild hair is a trope of its own for mad scientists and professors in popular culture. Einstein’s discoveries led to modern-day inventions ...
