Mind blown.

Galaxy Brain

In an extremely cosmic-brain take, University of Rochester astrophysics professor Adam Frank suggests that a civilization could advance so much that it could eventually tinker with the fundamental laws of physics.

It's a mind-bending proposition that ventures far beyond the conventional framework of scientific understanding, a reminder that perhaps we should dare to think outside the box — especially as we continue our search for extraterrestrial civilizations.

If a civilization were to be able to change the laws of physics, "the very nature of energy itself, with established rules like energy conservation, would be subject to revision within the scope of engineering," Frank, who is part of the NASA-sponsored Categorizing Atmospheric Technosignatures program, wrote in an essay for Big Think.

Playing Games

For instance, as astrophysicist Caleb Scharf argued in an eyebrow-raising 2016 article, an alien civilization could conceivably be behind dark matter, the theoretical stuff that — as far as our current understanding of the universe is concerned — makes up the majority of mass in the universe.

Frank takes the concept even further, suggesting advanced alien civilizations could "mix and match physical laws any way they see fit."

It's all pretty far fetched, and the astrophysicist is the first to acknowledge that, pointing out that at this point it's primarily just "fun" to think about these things.

Frank concludes that while controlling these laws may be pretty unlikely, it's far more likely that they put "severe limits on life and what it can do."

So it's possible that "there simply is no way around the limits imposed by the speed of light," Frank concedes.

But it's nice to dream.
