When studying a complex system, scientists identify smaller pieces called subsystems that they can make sense of. By studying subsystems and the correlations between them, they reconstruct an understanding of the whole.

A huge amount of mysterious dark energy is necessary to explain cosmological phenomena, such as the accelerated expansion of the Universe, using Einstein's theory. But what if dark energy was just an illusion and general ...

Einstein's theory of general relativity holds that a massive body like Earth curves space-time, causing time to slow as you approach the object—so a person on top of a mountain ages a tiny bit faster than someone at sea ...
