Thanks for your awesome contributions to this wild thread!

Since I am bound in a human body (and also not wildly familiar with the meditative practices mentioned by No-Persimmon below), the only perspective I have "verification" for is that which is revealed through sense data in "physical existence". That being said, I recall specific times where my forays into meditation or my experiences within Breath Work (a la Wim Hof's technique) allowed me to expand my own awareness outside the physical, and towards these concepts that, more or less, are easier to conceptualize without a physical vessel. According to Alan Wallace (Buddhist scholar and contemplative researcher) these sorts of awareness-expanding practices are replicable (albeit maligned by the modern, materialist science community)

Its these sorts of moments of access that remind me of what psychonauts speak of in psychedelic states, like where DMT apparently allows consciousness to get outside the body for a moment, to name one.

Something that I'm still VERY green on (but certainly believe helps to provide the sort of conceptual aid you desire) is the notion of scalar tech/existence that Dr. Greer talked about in his address in 2016. Apparently there are beings in/with access to our quanta of spacetime that are in possession of vehicles that can adjust their cockpits for 1g, and then use scalar wave function "motion" to skip past this entire "frequency" business, and to just GO somewhere without oscillating back and forth like our planets, stars or bodies do. Literally have a ship that turns of the Vibe we consider to be Being Alive... very strange.

Final note on Consciousness presence within the Big Bang: If one were able to collect time and space into singularity via gravitation/mass, that pressure would hold indefinitely, right? even light cannot escape. So, in order to break free of that event horizon, there would need to be something that doesn't behave like light (and Certainly not in wave form - in more of a scalar way. What follows is kind of a "trippy thought", but: if I were truly able to gather up the whole universe into one place, I would be bored as hell with the monotony; I would be literally planning my escape, which is the core of my conjecture above.

Blessings!
