In the context of cosmology, it is widely considered likely that at least some, if not all, of the constants of nature had their values influenced or determined by random quantum mechanical fluctuations during the very early history of the universe.1

If this was the case, the constants could have taken values different from those currently observed. Some theoretical frameworks, such as the eternal inflation/string landscape model, suggest that there may be a multiverse consisting of many universes, each with different physical constants and fields. Within this perspective, the anthropic principle is used to explain why the constants in our observable universe take values compatible with the existence of life, as life could only arise in regions where the constants permit it.12

While it is not currently known why the constants take their specific observed values, it remains possible that they are the only logically possible values, or that they were set by processes in the early universe that could have resulted in different outcomes.1
