But what if Einstein’s theory of relativity offers a different perspective? What if our inner world, like space-time, is ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is ...
