In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

On one hand, the speed of light is just a number: 299,792,458 meters per second. And on the other, it’s one of the most important constants that appears in nature and defines the relationship of ...

The speed of light is the ultimate limit of motion, yet against the vast scale of the cosmos it becomes painfully inadequate.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
