Undated -- Imagine being onboard that first human expedition to Mars. Representing all of humankind you take your historical one small step, one giant leap onto the surface, only to find your legs ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Physics is filled with mysteries – and, believe it or not, gravity remains one of them. We rely on gravity to explain things large and small. But at a fundamental level, we still don’t fully ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Gravity's impact on bone cells—experiments heading to the International Space Station Mechanical engineers at the University of Michigan are tackling mysteries of bone density loss in space and on ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...

WEST LAFAYETTE, Ind. — For astronauts to go on long missions to the moon or Mars, they need a refrigerator. But today’s fridges aren’t designed to work in zero gravity – or upside down if oriented ...
