What if gravity repelled instead of attracted? This video explores how repulsive gravity could have shaped the history of the universe. Gravity was traditionally defined by Isaac Newton’s Law of ...

All fundamental forces operating on astronomical scales exhibit a decrease in strength with increasing distance. A hypothetical force, decreasing with distance slower than the inverse square law, ...

New research could help scientists use gravitational lensing — the warping of light from distant galaxies — to investigate the accelerating expansion of the universe. When you purchase through links ...

Dark energy is the name physicists have given to the mysterious thing driving the universe's accelerated expansion. It may be a force or a form of energy, and one piece of evidence suggests it is ...

In the Alpine town of Arbedo-Castione, Switzerland, an electric-blue, 400-foot-high crane with six heads lifts a block of compacted soil into the air and carefully adds it to the top of a stack. Later ...

WASHINGTON, Nov 19 (Reuters) - Scientists working in an international collaboration have tracked how the structure of the cosmos has grown over the past 11 billion years, providing the most precise ...

"Studying the rate at which galaxies formed lets us directly test our theories and, so far, we’re lining up with what general relativity predicts at cosmological scales." When you purchase through ...

Energy innovators around the world plan to harvest more power from abandoned coal mines, but not by digging up dirty deposits. Instead, this concept utilizes gravity and renewable energy to transform ...
