Big G, gravity, is the oldest fundamental constant in physics and the least clearly defined. One scientist has spent a decade ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American When Max Born addressed the South Indian ...

A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, ...

Billions of years ago the strength of the electromagnetic interaction was different at opposite ends of universe. That’s the surprising conclusion of a group of physicists in Australia, who have ...

Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps our feet on the ground and holds planets in orbit. Related video above: ...

The long-standing problem of the cosmological constant, described both as “the worst prediction in the history of physics” and by Einstein as his “biggest blunder”, is being tackled with renewed ...

A fundamental constant of the universe may not be soconstant after all, according to a new study. Recent observations of distant galaxies suggest that thestrength of the electromagnetic force ? the so ...

We live in an age—perhaps the age—of confirmation bias. And given a turbulent sea of information, who can blame us for latching onto the familiar while looking away from anything jarring or mismatched ...
