Theory that challenges Einstein’s physics could soon be put to the test
Scientists behind a theory that the speed of light is variable – and not constant as Einstein suggested – have made a prediction that could be tested.
Einstein observed that the speed of light remains the same in any situation, and this meant…

Atomic beltway could solve problems of cosmic gravity
When is a traffic jam not a traffic jam? When it’s a quantum traffic jam, of course. Only in quantum physics can traffic be standing still and moving at the same time.
A new theoretical paper from scientists at the National Institute of…

Ancient supernovae buffeted Earth’s biology with radiation dose, researcher says
Research published in April provided “slam dunk” evidence of two prehistoric supernovae exploding about 300 light years from Earth. Now, a follow-up investigation based on computer modeling shows those supernovae likely exposed biology on our…
