Viewpoint: Black Holes Produce Complexity Fastest

[QuantumQuest]

Yesterday I came across this article about speed limit on the growth of complexity in quantum gravity, that I found interesting:

Theoretical results suggest a precise speed limit on the growth of complexity in quantum gravity, set by fundamental laws and saturated by black holes.

The article is in APS Physics:

In recent years, physicists have been investigating the notion of complexity in quantum gravity, which is described as the number of degrees of freedom that a system can contain. It has been suggested that there exists a fundamental limit to the growth of complexity in quantum gravity, set by some kind of universal law. This speed limit on complexity growth was recently suggested by researchers from the University of Cambridge.Their findings suggest that the speed limit for complexity in quantum gravity is set by the fundamental laws of nature and is saturated by black holes. They found that the maximum rate of complexity growth is determined by the area of a black hole's event horizon, divided by Planck time. This implies that any system subject to quantum gravity cannot evolve faster than a black hole of the same size.The findings of this research are important for the development of theories of quantum gravity, as they provide an upper speed limit on the growth of complexity in the universe. The implications of this speed limit could be far-reaching, impacting our understanding of the evolution of the universe and the emergence of structure within it.
