Disclosure: more questions than answers. Actually, all questions, no answers. Just some recent thoughts.
We live in 3D. That is, 3 spacial dimensions. Length, width, height. The addition of time gives us spacetime, and a 4th dimension. M-theory, or string theory, posits multiple dimensions, up to 11. 10 spacial and 1 temporal.
If time is the 4th dimension, and there are multiple spatial dimensions of which we are unaware, could there be multiple times? A sort of cosmic layering of times, but we are only aware of ours?
If my eyes are adjusted to the light of my computer screen, everything around me is black. When I glance up, and my eyes adjust their focus, I can perceive objects in my room. Similarly we see the world in the daytime, and when night falls, we can then see the stars. From our nighttime observation, we infer they are always present, but we cannot see them in the daytime. It is only with the perceptive veil of light removed that they enter our awareness. It’s interesting, that light sometimes illuminates and other times it hides. (Or, perhaps, it's always doing both.) But, of course, we only see the stars because they emit light. What would happen if the stars ceased to shine? If we could remove their veil of light. Would something else remain? Of course this is just light and dark, the two sides to our reality of only one of our senses (albeit one we seem to trust more than others), sight, but what other layers of other senses remain that we have yet to dig deeper within? And moreso, what exists beyond the senses?
It’s consciousness. Reality exists when we bring it into our consciousness. So the world exists as a continuum of each being's consciousness. An intricate web of awareness.
What would happen if every person in the world were to go to sleep at the same time? Meditated? Focused their consciousness on a single entity? What would be created?
In what dimension?
