I can show you photos of the Death Star. Extra dimensions, worm holes, touching dimensions, is all the result of String Hypothesis (No, not a theory) A hypothesis is a guess, it becomes a theory when supported by falsifiable, repeatable experiments. That does not just include a dry erase board.
All those extra dimensions have one purpose. To explain a math error. Physics is in a Salem zone in recent decades. They are desperate for a unified theory. The math predicts something that doesn’t exist, so we are told it’s invisible and cannot be detected.
I really wish wormholes and curved space existed. Then I could step out of a house in Denver, and step onto a beach in Mexico. But I can’t... and you can’t either.
And the UFO Tic Tac craze is a media hyped craze, infused with money, fame, and the powers that be putting a shiny object out there to distract from them conquering the planet.
People have seen things since ancient times.
The ONLY place one can sense a hyperspace being is where that being is IN the four variable limits of our sensing. without the extra variable(s) we cannot detect those other variable levels. BUT mathematics can describe them.
