Oh, no! Not again! The rebellious... demon... inside me wants to get out... again... BRACE YOURSELVES!
*Tushantin has transformed into Super Antagonistic Mook again!*
....so what if we found out the way the universe was created? What difference would it make?
That's exactly what Sherlock Holmes says: "You say that we go round the sun. If we went round the moon it would not make a pennyworth of difference to me or to my work."
But ya know, I'm no Sherlock Holmes. If we find out how the universe was created, it would not only alter the paradigms of science and religion themselves, but also my entire direction of artistic endeavors. It would make our whole existence clearer, give us better means to design our evolution and development, understand the universe we live in even further, unlock the mysteries of the fabric of space and time itself that was created past the Singularity explosion (aka the Big Bang), etc.
And you know what else? We'll even have a freaking sitcom based on the new science theories! (Somebody, please kill me!)
It's like discovering who Jack the Ripper was; sure you might feel the need to know, but in the end it makes no difference besides fulfilling our curiousity. His victims are still dead, we can't punish his descendants, the murders happened, and that's all there is to it.
It's like when anecdotes go weird, and we're attacked by dinosaurs due to literary paradoxes.
Discovering who Jack the Ripper is (if you actually mean Jack to be a "metaphor" for mysteries of the past events) actually becomes the foundations of our very existence. They say that those who do not remember historical events would not learn from them, and hence are doomed to repeat it. And sometimes, the answer to the future always lie in the past (check: Chrono Trigger). And just to play with even more taglines / mottos, "Knowing is half the battle".
See, learning who Jack the Ripper was won't really bring back dead, nor does it give us the right to punish his descendants. But knowing
who he was and
how he did it will essentially am us against such "kinds" of criminals in the future too. If you don't recall, we've actually had plenty of Lambeth Poisoners, Adam Worths, Frank Abagnales, and the recent star Adam Lanza. But the only reason we don't have more than there were is because we uncovered the mystery, learned from it, and made sure it doesn't happen again.
On top of that, knowing the name of criminal doesn't just give the detective the means to have him arrested, but also unlocks a whole new world of tales that not many people would ever know about (think: Adam Lanza, the boy who was never known until he somehow "snapped" and went on a rampage). I'm not saying that such stories are entertaining (unless some artists seek some kind of inspiration for a new mystery / drama novel), but the more information we have the more we can revise and refine our methods to work better. A simple incident like that made a whole nation demand for banning assault rifles for good; but that's just the start of it many connections in fate that are about to happen.
Now (back to objective point of view), how would Jack the Ripper's identity affect us? Frankly, I haven't the foggiest. But that's the thing about the human intelligence: it rarely knows more than 1% of what the universe may allow, and we hardly know more the other 99% of the components that make the universe (categorized under Dark Matter, Dark Energy, or spectrums we haven't yet found means to detect, etc.), or how that may affect us in the first place. In essence, the only way to know what difference it makes is to actually know about it. Though, if there's one thing I do know, the knowledge about Jack the Ripper would finally make all those horrible (only horrible, not the "good" creative ones) works of fiction based on him entirely invalid.
So in a closing statement, I'll say this: "Knowledge is Powah!" (And no,
don't fight this powah)
*Super Antagonistic Mook loses power, turns back into the dazed-out Tushantin*
Uhh... what happened? *looks into the mirror* Am I wearing a bow-tie?
