How to "visualize" dimensions; a very interesting explanation by 10Dim. If you are into cosmology, FTL or interstellar travel and exploration of deep space, this video offers some unconventional ideas that are worth considering, like that of an omniverse, which you could understand as being above the multiverse in which our universe exists.

I recommend you to watch this video repeatedly; it is not difficult to understand what is presented. However, the ideas of the author are provocative and need a little bit of thinking before they can be grasped.

Really good (I liked especially the reference to the Flatlanders), and also makes an excellent topic to talk about in front of a fire at any camp!
