In simple words, this new framework ... For example, general relativity predicts a black hole’s core is infinitely dense, while quantum physics suggests such infinities can’t exist.

Einstein's theory of general relativity changed how physicists understood the universe in an instant. One hundred years later, they are still proving him correct.

Even extremely simple configurations in General Relativity cannot be solved exactly. Here's the science of why.

Einstein published a new theory of gravity—the theory of general relativity—in 1915. It would transform our understanding of physics forever. But it’s far from perfect.

However, all attempts to blend general relativity and quantum physics necessarily introduce deviations from Einstein's theory. Therefore, Einstein's gravity cannot be the ultimate theory of gravity.

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This article was originally published at The ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

The theory of general relativity utilizes the idea of a curved space-time to explain gravity and has been widely validated, despite unresolved questions regarding dark matter and dark energy. On the ...
