Albert Einstein on a bill of 5 Israeli Pounds. A truly spectacular unpublished autograph manuscript produced by German physicist Albert Einstein (1879-1955) and exploring his celebrated Unified Field ...

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 ...

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 ...

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 ...

Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity. But a new study goes one step ahead; it not only links the two theories but ...

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.
