For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime.

Mind = blown.

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.
