You can find seemingly zillions of matters which can be theoretically proposed which makes no sense. The classic modern example is String Theory which requires six additional spatial dimensions apart from latitude (north-south), longitude (east-west or left-right) and altitude (up-down) you are familiar with. However there’s additionally a whole pot-load full of experimental reality and observations .
Some parts of reality have been shown to departure as reality yet as Mr. Spock would have it, are illogical.
For instance, is a trilogy of generations. For instance, there is the electron, the heftier muon (father or son) and the even heavier tau (the electron’s grandpa or grandson). Now you’d believe their comparative masses would bear some kind of logical connection like 1,2,3 units or 1,2,4 units or 1,3,9 units. But no, it’s all ad hoc like numbers determined with enormously more amounts by three spins. Now this would not be too terrible if the muon and the tau particle actually did anything. They can be produced, nevertheless they decay and go ‘poof’ so quickly that they play no active part in virtually any reality working with life, the universe and everything. That is an alternative reality, or the first impossible reality, you need before being served breakfast to accept.
There’s matter or mass that socializes with electromagnetism, the kind of stuff we know and deal with every day. You’re that sort of matter. But, reality also has it that there is matter or mass that will not socialize like light, with electromagnetism. You can’t see this matter. It is matter that is imperceptible. It’s called Dark Matter. If you’d a ‘basketball’ made out of Dark Matter and it proved to be a foot before your face, you can not see it even in a brightly lit room. That’s insane. This is the hopeless that is 2nd reality, another alternate reality, you need to accept before being served breakfast.
