Special relativity. Einstein's theory is divided into special and general relativity. Special relativity came first and is based on the speed of light being constant for everyone. That may seem ...

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.

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new ...

Earlier this year, new research suggested a potential solution to one of the most troubling aspects of modern physics — that ...

This week marks the 100th anniversary of the publication of papers laying out Albert Einstein’s theory of relativity. In honor of the anniversary, Gwen Ifill examines how Einstein changed our ...

The general theory of relativity, Einstein asserted, was now complete. The month leading up to the historic announcement had been the most intellectually intense and anxiety-ridden span of his life.

The Theory of Financial Relativity. Now how does this apply to your finances, particularly as you plan for retirement? Well, your finances are relative. To start, there’s no magic number that ...

The theory of financial relativity. Now that I’ve set the groundwork, let’s talk about the 21st century’s huge breakthrough of the theory of financial relativity.
