“Some truth can be true today and false tomorrow.”
No, that is a mistake. Every true statement is always true. The postmodernists and linguistic analysis tried to put that one over, but all statements are contextual and the kind of argument you are making can only be made by dropping the context.
For example, if someone says, “Harry is still alive” on thursday, when Harry is alive, and Harry drops dead on Friday, someone might say, “the statement, “Harry is still alive,” is no longer true. But that drops the unstated (but understood) context, which is, “On this Thursday, Harry is still alive,” and that statement will be true for eternity because on Thursday, Harry was still alive, and will always have been alive on that Thursday.
Many, possibly most, fallacious arguments come from dropping the context of atatements. The most famous class of such fallacies is Ayn Rand’s identification of the “floating abstraction.”

You have stumbled on the "observer problem"..
What one observer sees/notices can be occluded to another observer.. due to time or qualia or position.. Assuming humans can even see reality clearly or at all..
As I said, as Jesus said, reality and truth is not in a statement, theory, assumed fact, or mental figment but in a person.. Jesus is truth.. Its hard to get your mind around that at least for me.. But if, Jesus is truth, everything else isn't, by itself..
It is possible humans with picayune sensory organs and multifarious mental problems(blind spots) cannot see universal reality as it is... Truth then would be "roll your own" observations.. basically opinion.. The life of a scientific fact is timestamped..
