The Fine-Tuning Problem

Change any of the 26 physical constants by a millionth and the universe couldn't exist.

The universe rests on physical constants whose values are incredibly finely tuned. Seen through simulation theory, they look like the settings in a program's config file. Pick a constant below and change it with the slider.

UNIVERSE STABLE

With all constants perfectly balanced, stars form, atoms bond, and life develops.

Scientists also try to explain fine-tuning with ideas such as the multiverse or observer selection. Simulation theory offers a simpler answer: someone chose the settings.

Simulation A: Beat the System

The System learns your choices and seals its prediction before you tap. 24 layers, five experiments, a new experiment every day. Can you really be random?
