Astrophysicist Max Tegmark has a lot of material about levels of Multiverse on his website

Maybe the Dot is a portal to parallel worlds!   

I love this channel, along with PBS Spacetime[1]. Pure hard science, but it's hard not to see the parallels to the contemplative traditions.

What it suggests to me is that our experiences only appear to be time-bound by our perceptions; whatever is "out there" beyond the senses (postulating that there is anything...) it's more like a highly dimensional object that contains possibilities, and our senses are one way of traversing the nodes of that object. Your current experience is because of past actions that make it more likely you're perceiving this 'self' than another 'self' on a different path. The path of liberation is then optimising so that you make it more and more likely that you will have the conscious perception of the 'awakening' parallel reality than not. 

Of course, then you add in not-self and the whole thing falls apart... Theoretically and perceptually

I have no clue really I'm not at all intellectual nor scientistific or even philosophical. I would be an artist mind that can express much easier with abstract paintings or music. 

All this talking and describing of meditative experience is hard for me. Maybe that's why I prefer the matter of fact simple, sensation by sensation noting/noticing. 

still I do enjoy such ideas and science that shake up the usual view.
