The late Professor Stephen Hawking revealed his answers to 10 "big questions" he was often asked in a new book published six months after his death.

The final paper that famed physicist Stephen Hawking worked on before he passed away deals with a topic bigger than Hawking's legacy.

The Large Hadron Collider (LHC), the world's largest atom smasher, just discovered at least two previously unknown particles.

The study of the subatomic world has revolutionized our understanding of the laws of the universe and given humanity unprecedented insights into deep questions. Historically, these questions have been in the philosophical realm: How did the universe come into existence? Why is the universe the way it is? Why is there something, instead of nothing?

Scientists have reached a “milestone” in a technique of semi-artificial photosynthesis that could eventually create an “unlimited source of renewable energy,” according to a new study.

It's the age-old question that always sparks debate.

Once again, scientists have shown that Albert Einstein's theory of special relativity is right — this time, thanks to a particle detector buried deep beneath Antarctica.

Scientists have captured a ghost-like subatomic particle on Earth, helping to solve a mystery baffling scientists for 100 years.

Scientists have produced the firmest evidence yet of so-called sterile neutrinos, mysterious particles that pass through matter without interacting with it at all.

A new NASA study shows that humans are responsible for major changes to Earth’s water availability.
