The Anthropic principle

The Anthropic Principle is the idea that the universe's laws and constants appear fine-tuned for the existence of life because we are here to observe it. In essence, it suggests that the conditions we see in the universe are not random, but rather necessary for our existence. If the universe were different, we wouldn’t be here to notice it. This principle can be used to explain why certain aspects of physics and cosmology seem precisely aligned to support life, emphasizing that our observations are, in a way, shaped by our own presence in the cosmos.
