For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal — that is, if it looks the same no matter how large the scale.
Big Bang theory is the leading explanation for how our universe began. According to the theory, the entire universe began as a tiny singularity that went through an explosive expansion 13.8 billion years ago, gradually expanding into the cosmos we see today. Today, astronomers can detect an "echo" from the Big Bang in the cosmic microwave background, a phenomenon that can be detected with radio telescopes. Big Bang Theory is also the name of a popular CBS sitcom about scientists, where several real-life scientists and astronauts have appeared.
Space.com caught up with Greene to discuss the importance of science education, why black holes are so interesting and whether a "theory of everything" breakthrough could be on the horizon.
Believe it or not, physicists are attempting to understand the universe when it was only a handful of seconds old.
Cosmologists simulated 4,000 versions of the universe in order to understand what its structure today tells us about its origins.
Scientists have spotted the first evidence of a rare Higgs boson decay, expanding our understanding of the strange quantum universe.
A new study on the rotation of the universe's first light could suggest physicists need new rule-breaking subatomic particles
A mysterious "kick" in the early universe may have produced more matter than antimatter. And that imbalance may have also led to the creation of dark matter, researchers now say.
Scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).
Tracy Slatyer, known for hunting dark matter in our galaxy and discovering evidence of an ancient Milky Way explosion, has won a $100,000 prize funded by tech billionaires.
A few scant equations can explain a variety of phenomena in our universe, over vast gulfs of space and time. Here's a taste of just how powerful modern physics can be.
A key signal for a certain kind of dark matter failed to turn up in a search throughout the Milky Way. Now scientists are disagreeing about what that means.
Astronomers have probed the Perseus galaxy cluster in search of an as-yet undetected particle that would help support string theory.
As the universe cooled in the era after the Big Bang, a supermassive black hole had already formed in the center of a galaxy, forming a giant engine of energy we can still see today.
