Scientists are speculating that gravity is actually a force caused as part of the universe’s tendency toward entropy. Furthermore, the effect may have something to do with the way in which spacetime erases information on its march in that direction. The broader relevance of information is the interesting part:

Over recent years many results in quantum mechanics have pointed to the increasingly important role that information appears to play in the Universe.
Some physicists are convinced that the properties of information do not come from the behaviour of information carriers such as photons and electrons but the other way round. They think that information itself is the ghostly bedrock on which our universe is built.
Gravity has always been a fly in this ointment. But the growing realisation that information plays a fundamental role here too, could open the way to the kind of unification between the quantum mechanics and relativity that physicists have dreamed of.

Metaphysics would seem to enter the unification, as well, leading through worldviews and religion. Think how easily the statement that “information carriers” come from information about them, rather than generating information, translates into a contradiction of the belief that human consciousness is a coincidental consequence of our biology.
