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 ...

The loudest collision ever recorded between two black holes has allowed scientists to test Einstein’s theory of general relativity in unprecedented detail, showing that the physicist’s predictions ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

The earliest test of Albert Einstein’s general theory of relativity took place just four years after he published it. During the May 29, 1919, total solar eclipse, British astronomer Sir Arthur ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, which are challenging the completeness of Einstein’s general theory of ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window into the universe’s most extreme events. These collisions not only revealed ...
