General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

Learn how microgravity could affect sperm, fertilization, and embryonic development in space.

The scientists also looked at the effects of exposure to microgravity had on embryo development in the animal models, and the ...

It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in ...

Gravity’s always been my favorite force. I’ve been cheering from the front lines as it’s consistently exceeded expectations, mapping massive globs of invisible matter, bending light to magnify infant ...

The International Space Station is humanity’s most expensive gym membership. Since the earliest days of human spaceflight, it’s been understood that longer trips away from Earth’s gravity can have a ...

Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a property that emerges from some deeper physical interaction. This emergent ...

A second-grade student from California has designed the mascot that will join NASA's Artemis II mission to the moon -- known as the zero gravity indicator.
