The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make up nearly 70% of the cosmos, has been the leading explanation. But a new ...

A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary ...

Although we take a lot of scientific knowledge for granted today, each of the basics – whether it be about light, gravity, mass or the shape of the Earth – had to be theorized and experimentally ...

For decades cosmologists have wondered about the nature of dark energy, the proposed antigravitational force behind the accelerating expansion of the universe. Since the 1990s astronomers have ...

The first planned artificial gravity experiment took place in late 1966, but the first human on the Moon beat them to it.

Though spacecraft with artificial gravity are still a distant dream, we had proof of concept way back in September 1966.
