>>13615654>Flat circle>Time is two-dimensionalTime is bullshit to explain so lemme break it down into contextual explanations
>Time as viewed through a single pointIt's linear, there's forwards and backwards and that's it.
>Time as viewed by an outsider to the 3rd dimension (objective viewpoint)Time is now a plane, with all events simultaneously happening taking up one line and the time at which they happen taking another.
>Time as viewed through a point in the 4th dimensionTime is no longer flat. It takes a 3rd dimension concerning the possibilities that each possible change in causality could have, though this is not observable to beings lacking in a dimension.
For the sake of lack of headaches, the dimension adding stops there, length of the line, area of the plane, and volume of the 3rd dimensional object are all unknown to those that can't observe it objectively. The shape as well. To say it's a square or a circle would be simply wrong.
>inb4 muh multiverseConcepts relating to what-ifs stretch into the fifth dimension as you have to consider things outside of causality that are different as well when it comes to multiverses. As such, it's best to just not consider them.
