I see it more as if the universe was a 4D picture, with time as the 4th dimension, any concept of time "going forward" is just an illusion by how our brains work (we need time to compute every moment), so the outcomes are already written, we just havent seen it.
- ebg13 7y agoIn that framework something most still be moving through an external time to be experiencing individual parts of it sequentially.
- o_p 7y agoWhat do you mean by experiencing sequentially?
- tylerjwilk00 7y agoHe means We (you, me, other humans) experience time passing consciously and sequentially. We are on the inside of a 4 dimensional bulk. We are traveling through the temporal dimension. As opposed to outside of it looking in. In which case we would "see" past, present, and future simultaneously.
- ebg13 7y agoBetter yet, if we're traveling through that temporal dimension there must be real time. Otherwise how would we be traveling?
- gicop 7y agoHere's a thought experiment, similar to the one-electron universe thought experiment: there exists one particle, the "consciousness particle," which randomly jumps around throughout 4D space. Whenever it appears at a 4D position, consciousness is experienced as computed by integrated information theory (or a similar model) [1]. When you experience a moment of consciousness at a specific 4D position, you experience all the memories of the "past" that are in your brain. Thus, the consciousness particle interpretation of consciousness is compatible with your direct perception of living a 3D life along a time dimension.

- ebg13 7y agoYou still need real time for this. Without real time that particle can't move.
- tylerjwilk00 7y agoSo basically we're all the same person we just think we're different people.

- phkahler 7y agoI have long been a fan of the 4d fixed universe. If you think of fractals you can get a hint at how everything is interrelated. As you indicated, the fundamental issue is why we experience the passage of time. I dont think it's an illusion, but the most important question.
