‘Now’ is the universal constant

In Einstein’s spacetime, the speed of light is the universal constant. His theories are great at describing the laws that govern our physical bodies, but what about our minds? The only truly constant thing we know in life is the mind-body experience we call ‘now’. Every body that has mass has an inescapable gravitational field for itself. We can never move in space relative to ourselves. We can also never stop moving forward in time at one second per second, relative to ourselves. But then how do we remember the past or anticipate the future? Our past and future exist as points in the spacetime continuum. Physically, we can never visit these. But mentally, we must be able to, or else the present would make no sense. Imagine listening to just one note, or section of a song. It wouldn’t make sense without the context of what came before, and what is coming after. Our experience of the present is the same - past, present and the future all exist at once in our minds to make up ‘now’. All points in the spacetime continuum exist in ‘now’. The experience of ‘now’ never changes, no matter where a conscious entity exists in spacetime. Our physical bodies age, but aspects of our consciousness stay the same throughout our lives. I believe this reconciles the gap between the theory of relativity and quantum mechanics. Things can happen in our minds faster than the speed of light. We can go back in time and relive memories. Quantum entanglement shows that there is connectedness in the physical world that cannot be explained by physical communication, which is limited to the speed of light. Our minds are able to freely traverse the spacetime continuum. The double slit experiment shows that we cannot observe something without affecting it. My interpretation of this is that we create the physical world by observing it. Because we are conscious, the physical world exists. Because we can only be conscious ‘now’, spacetime - all of it - must exist ‘now’. I have no idea if this can be expressed by math, but I believe it to be the true nature of the universe and metaphysical existence.
