That said, in the absence of a deeper theory, it is hard to estimate exactly how fine-tuned our universe is.

This is the heart of the fine-tuning argument: that the universe appears to favor the existence of life. So why are we here? One answer is to simply end the line of thinking right there.

This is just one example, and there are many others. The most popular explanation for the fine-tuning of physics is that we live in one universe among a multiverse.

Physicists have long grappled with the question of why the universe was able to support the evolution of intelligent life. The values of the many forces and particles, represented by some 30 so ...

Our Universe is not fine-tuned for life, but it’s still kind of OK Inspired by the Drake equation, researchers optimize a model universe for life.

One of the examples of fine-tuning which has most baffled physicists is the strength of dark energy, the force that powers the accelerating expansion of the universe.

Our calculation finds that most observers among all universes will experience a higher dark energy density than is measured in our universe. Also, we found that the most typical observer would measure ...

In terms of fine-tuning, the most specific evidence that people who believe in the multiverse have is not merely that a universe is fine-tuned, but that this universe is fine-tuned.

It appears that we live on the knife-edge, where only the narrowest combination of values for the fundamental constants allow life, and especially conscious life, to arise.
