Your answer is absolutely true, but according to RL’s previous post, he mentioned the following: “It is probable – at least scientists certainly hope so- that there will be a more complete theory that unites General relativity and quantum mechanics, this theory will look very different than any that came before it- but we do know that it will not ‘disprove’ general relativity or quantum mechanics- it will show how they are connected.”
My question then is: If someone does come up with a “theory” that unites general relativity and quantum mechanics, how will the “scientists” recognize it?

On the other hand; considering the pandemic and the political unrest in the world today perhaps there will be no “scientists” in the future at all.
By the way RL’s comments should be in the “FLAME” board.
