Every time an astronaut returns from space, they experience a force four times their body weight. As they leave the ...

Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a ...

Gravity is the only major force in the universe that doesn’t fit into our current quantum framework, driving the pursuit of a grand unified theory of physics. The new test would not be proof or ...

Gravity is the only major force in the universe that doesn’t fit into our current quantum framework, driving the pursuit of a ...

Einstein showed us that gravity is not a mere force but is rather the foundation of cosmic structure. Gravity, Einstein said, defined the structure of space and time itself. But in the past ...

The search for quantum gravity has gone on for 100 years, but it is not the only unification challenge in physics. Many of us ...

Great! So, what's gravity? Aaaah, gravity is the force that makes objects fall towards the ground. And, without gravity, we'd all float! Hmmmm… You're right! The force of gravity is weaker on ...

Scientists working in an international collaboration have tracked how the structure of the cosmos has grown over the past 11 billion years, providing the most precise test to date of how gravity ...

The ideal solution, it’s been argued, is to design future spacecraft with the ability to impart some degree of artificial gravity on its passengers through centripetal force. The technique is ...

To simulate free falling, New Scientist took her indoor skydiving at iFLY London, where she explained how gravity acts on every cell of your body in the same way. However, this force still isn’t ...
