General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1916. It unifies Einstein's earlier special relativity with Sir Isaac Newton's law of universal ...

Until now the history of knowledge has largely been about formal and documented accumulation, concentrating on systems, collections, academies, and institutions. The central narrative has been one of ...

This year marks the 100th anniversary of a scientific breakthrough that fundamentally changed our world. In 1915, Albert Einstein presented his theory of general relativity, which proposed that ...

Albert Einstein released his general theory of relativity at the end of 1915. He should have finished it two years earlier. When scholars look at his notebooks from the period, they see the completed ...

Simulated universe: EAGLE collaboration, J Schaye et al 2015. MNRAS, CC BY-SA A renewed suggestion that dark energy may not be real — dispensing with 70% of the stuff in the universe — has reignited a ...

IntroductionIn this series, we are testing the idea that "the universe might be a simulation running on a giant computer" by ...

More than a century ago, Albert Einstein conjured the hypothesis of all hypotheses — an idea so extraordinary it would relentlessly echo through the vast directory of human thought. It would alter the ...

Albert Einstein’s general theory of relativity has been wildly successful at describing how gravity works and how it shapes the large-scale structure of the universe. It’s summed up in a saying by the ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

Proposals offering alternatives to Einstein’s relativistic theory of gravitation are almost as old as the theory itself. Einstein even saw them as the beginning of a path that could lead to quantum ...

Spanning almost all of Nevada and Utah and portions of California, Idaho, Oregon, and Wyoming, the sparsely populated regions of the Great Basin and the Basin and Range Province have stories to ...
