The principle of uniformity
, or the "The Principle of Uniformity of Nature", postulates that the laws of nature
discovered on Earth
apply throughout the universe.
There are several variations and corollaries:
- A stronger uniformity principle is that the laws of event causation have remained constant throughout time (uniformitarianism) as well as applying everywhere in the 'modern' universe.
- A corollary in Physics is the postulate that there has been no change in the fine-structure constant since the Big Bang.
- Another corollary of the Principle of Uniformity states that nothing that is now impossible in principle was ever the case in the past.
