Here are 11 theoretical or conceptual dimensions often referenced in physics, string theory, and science fiction:

First Dimension – Length (a straight line, only one direction)

Second Dimension – Height (adds a perpendicular direction to the first, forming a plane)

Third Dimension – Depth (adds volume to length and height; our physical space)

Fourth Dimension – Time (movement or change over time)

Fifth Dimension – Possible worlds (all possible timelines of our universe)

Sixth Dimension – Alternate realities with different initial conditions

Seventh Dimension – Access to all possible timelines of all possible universes with different laws of physics

Eighth Dimension – All possible universe histories and futures

Ninth Dimension – All possible laws of physics and initial conditions

Tenth Dimension – All possible realities and everything that can be imagined

Eleventh Dimension – The theoretical dimension in M-theory where strings are actually membranes (branes)
