Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

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 ...

The idea is still new and requires a lot of assumptions in its calculations to make it work. Over the years, experimental results have been mixed. When you purchase through links on our site, we may ...

The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't ...

Superb engineering. Low-key appearance. Light, efficient for its carrying capacity. Can charge fast at Tesla Superchargers, despite high-voltage architecture. Not the cheapest 7-seat EV SUV by far.

Hindsight, as they say, is 20/20. The Lucid Air is objectively one of the most impressive electric vehicles money can buy right now – a range king with incredible technology and mind-bending ...

Following the life-threatening snowplow accident that broke 30 bones in his body, actor Jeremy Renner is using an anti-gravity treadmill as part of his recovery process, multiple media outlets report.
