A plane of existence often compared with geometrical shapes. There are a total of 26
spacial dimensions according to theoretical physics. However, pop culture has twisted its meaning and associate dimensions with universes. For example, travelling to a different dimension is usually thought of as travelling to a different universe. The term "
Interdimensional" supports this claim by having a connotation related to that of the multiverse. It is important to understand the difference between these two, because movies and TV shows are getting the science of theoretical and
astrophysics wrong.
Friend: Bro, did you watch "
Phineas and Ferb; Across the Second Dimension"? It was LIT!
Me: Yeah, but the title is incorrect in so many levels. First off,the animation is in 2d. That's like saying humans reaching the 3rd dimension. Second,they meant universe. A dimension is a plane of existence,not a universe. Pop culture keeps getting that wrong. And finally, it shouldn't even be a universe. The laws of physics in that second universe would be
incompatible for the lead cast members. It should be called an alternate timeline, in which Dr.Doofenschmirtz succeeds at dominating the Tri-State area (even though he can go bigger and dominate the world, he does have the technology to do so).
Friend: I think you've been reading "
Hyperspace" far too many times, you're overthinking a kids movie.
