Throughout the universe, there are several underlying principles that we consider to be constants; for example, the speed of light in a vacuum. So many different aspects of our understanding of the ...

There was a secret inside the envelope in the hands of Stephan Schlamminger, one of the world’s leading experts in experimental tests of gravity. He appeared to be on the verge of opening the envelope ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...

IN the year 1884, Prof. Dr. Franz Richarz and Dr. Otto Krigar-Menzel commenced a series of experiments having for their object an accurate determination of the values for the constant of gravitation ...

One of nature’s venerable constants – gravity – may not be the same for every type of particle in the universe, suggest new calculations. The finding could explain a persistent mystery regarding how ...

IT appears that before the advent of the theory of relativity the constant of gravitation was purely empirical. No theoretical estimate or discussion of it has at any rate come to my notice. It is ...

EMDrives are claimed to be propellentless space propulsion systems. If propellentless propulsion is possible it could enable fast human travel throughout the solar system and possible interstellar ...

What if gravity repelled instead of attracted? This video explores how repulsive gravity could have shaped the history of the ...
