Since Albert Einstein established his General Theory of Relativity 100 years ago, scientists have been at odds as to how it merges with quantum mechanics – all of the fundamental particles, including the ones that have yet to be discovered and three of the four interactions: electromagnetism, and the weak and strong nuclear forces.

The fourth interaction, gravity, which falls into Einstein’s theory, does not match with quantum mechanics, leaving scientists unable to establish a Theory of Everything that unify the both.

However, by digging to the very depths of reality, scientists are on the brink of discovering what makes up reality and how spacetime – the model that combines space and time – emerges.

Their theory is that information, to put it simply, underlies and makes the universe.
