what we do know and think we know is limited by our own imagination and world experiences.
i would confidently suggest the universe is that big there is going to be plenty of shit out there and most likely down here thats well outside of our understanding let alone explaining.
what would a caveman make of someone who travelled back in time and showed them a cheap bic lighter.
I agree. The caveman might think it was magic, and the time traveler would know that wasn't true, aware of the physical principles used both in the time travel, and the bic lighter
