The Tetraneutron
The tetraneutron is a hypothetical stable cluster of four neutrons. However, such clusters are not supported by current models of nuclear forces, so recent news of its
Dipole Gravity
Newton assumes in his work that gravity is a monopole acting with equal force in all directions, regardless of intervening matter. These assumptions are central to his shell theorem which
Satellite Orbits
Wikipedia claims that satellite orbits verify Einstein’s formulas for time dilation because the exact time and position of satellites are continuously adjusted. Their article makes it
Time Dilation Due to Gravity
According to general relativity, clocks slow down in the presence of massive bodies. This is known as time dilation due to gravity. The effect of gravity is in other
How Matter Dies
Empty space will produce electrons and positrons if subjected to a sufficiently strong electrical force. This manifests itself as gamma-ray radiation which
Two Bizarre Blobs Detected Deep Inside Earth
Studies of seismic data have recently revealed that Earth contains two large structures. One is located under the west coast of Africa.
Measuring Vacuum Permeability on Mercury
The laws of physics are assumed to be universal. This means that experiments performed on Earth should yield
Thinking About Gravity
The theory of physics presented on this website came about as a result of some intriguing problems related to gravity. The enormous size of many dinosaurs
The Nice Model of Solar System Evolution
Consensus building is a way to approach problems in which mediocrity of outcome is pretty much guaranteed. Anything original is tossed out as too
Sahara Dust Storms
The weather forecast was for sunny weather and temperatures reaching 20C, but instead we got three days with clouds and max temperatures of 17C. This hadn’t
