The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

KEY OBSERVATIONS Light from a dead star exploded ten billion years ago, yet it reached Earth not once, but several times, ...

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding challenged deep-seated assumptions about how space behaves on the grandest scales ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the driving force behind creation. Their simulations show that gravity and ...

When molecular biologist Francis Crick tripped on the psychedelic drug LSD in 1953, his mind famously pulled together all of his previous research on human DNA to conceive of the image of a double ...

Nearly a century after Albert Einstein and Niels Bohr turned a technical disagreement into a philosophical duel, a new ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...
