Last month's BICEP2 discovery of gravitational waves is compelling evidence for the inflationary period just after the Big Bang. But what if there's another explanation? Continue reading →
Gravitational waves have been observed for the first time, providing direct evidence for quantum gravity. How does this prove the Big Bang actually happened? Trace and explain this groundbreaking finding.
It's a wonderful moment in any scientist's career when they are informed that their bedrock theory is proven. Continue reading →
For the first time, scientists have found direct evidence of the expansion of the universe, a previously theoretical event that took place a fraction of a second after the Big Bang explosion nearly 14 billion years ago.
Albert Einstein wasn’t always convinced that the universe began with a Big Bang. Continue reading →
Theoretical physicists may have stumbled onto a solution to the black hole "information paradox" -- what if a black hole's singularity isn't an infinitely dense point in space-time? Continue reading →
After carrying out a vast survey using data from multiple observatories, astronomers think they've found the 'missing link' for the earliest compact galaxies. Continue reading →
Early planets may have harbored microbial life just after the universe started, warmed by cosmic radiation, says a new theory.
