[Tirong-say]

The veracity of theory and facts rely solely on our senses and perceptions of the things at hand.
Could we see an ultraviolet light with our own naked eye? no we could not, but we could by using available UV sensors. Then in what degree of capability do we have until now to detect all the things that surrounds us, nobody yet know, perhaps the theory that we have now may become false or may become true in the upcoming future.

Facts will result to two outcomes.
Prove and Disprove Theories.

Doubting Theories is normal.
