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.
