Causality in science

"One of the most established principles of logic / science / reality is the principle of causality: something that has a beginning has a sufficient cause".


Yes, scientists can PROPOSE THEORIES based on causality, but unless you have the data to support the theory, it means nothing. At the very least, you have to use probability statistics to demonstrate that the causality is extremely unlikely (less than 1% probability) to be caused by chance alone.

Always, you need data to support conjecture, otherwise it remains conjecture and science discards it.
