Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...
A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...
The Einstein equations remain the cornerstone of general relativity, underpinning our understanding of how matter and energy influence spacetime curvature. Recent investigations have not only ...
The evidence for the Big Bang is overwhelming, but we cannot describe what goes on in that event. We can’t accurately call it a moment; time as we know it did not exist. Our science stops making sense ...
Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...
Albert Einstein, in 1905, presented the revolutionary idea of light quanta of energy which equals ħw, where ħ is reduced Planck's constant. There is plenty of experimental evidence on magnetic flux ...

In the 53 years since Albert Einstein published his general theory of relativity, it has withstood determined attacks and ingenious experiments by other scientists anxious to test its validity.
