Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. Albert Einstein's 1905 theory of ...

A Growing Mystery The discovery of the Universe’s accelerating expansion in 1998 left scientists scratching their heads, ...

The other is Albert Einstein ... problem that Newton confronted and solved (almost). Einstein begins his work with one crucial insight: gravity and acceleration are equivalent, two facets of ...

On January 29, 1931, the world's premier physicist, Albert Einstein ... in the grip of gravity, the large-scale force that shapes the universe. Ten years later, in 1915, Einstein made up for ...

Get a sneak peek at Academy Award-winning actor Geoffrey Rush and newcomer Johnny Flynn as Nobel Prize-winning physicist Albert ... by Einstein's general relativity: Dark matter's gravity wrinkles ...

Albert Einstein predicted them in 1916 as part of his general theory of relativity. A US$1.1 billion set of instruments detected such a wave last September from a distant collision of two black ...

New research challenges the long-accepted notion of singularities in black holes — the point where physics allegedly breaks ...

Scientists announced they have directly detected gravitational waves for the first time, verifying an unproven portion of Einstein’s Theory of General Relativity. WSJ's Robert Lee Hotz reports.

Their approach also leads to a new way of understanding Einstein’s equivalence principle—the idea that inertial and gravitational mass are equal. In unified gravity, this principle naturally ...

Albert Einstein ... being hauled upwards. Gravity's tug and upward acceleration in zero gravity both pull you to the floor. The physics of both events is the same, Einstein decided, based on ...

In 1919, the Eddington experiment – a demonstration proving that gravity ... his life, Albert Einstein remained committed to strong ideals of social justice, democracy, and basic human dignity.
