A Fact is a Fact until it is no longer a fact.
The fact is facts change.
Facts change because reality is expanding & evolving.
A fact is whatever appears to be true at this moment in time.
To be a fact, it has to be experienced with the physical senses by a majority of people.
When a consensus of people believe it to be true, it becomes a fact.
It remains a fact until most people no longer believe it to be true because it is no longer evident from their experience.
Facts are a consistent physical experience.
Physical experiences may appear to be constant, consistent, & permanent but they are not eternal.
The only fact that is eternal is the fact that the reality that is experienced is a fact.
The fact is that reality is evolving and the truth changes with reality.
That is a fact until it is no longer a fact.
