Some Musings on the universe

I begin with Lawrence krauss’s idea which is the thought that if the total energy of the universe is zero then it’s conceivable that the universe came from absolute nothing. The evidence that the total energy of the universe is zero is the observation that the universe appears flat overall. Bringing in general relativity to justify this, a metric that is flat overall looks something like the Minkowski metric except that it may be locally curved however the total energy contributed by every inhomogeneity is zero.

The universe is then a mass fluctuation out of absolute nothingness but adds up to nothing and so could be considered nothingness which isn’t in equilibrium. There is a certain implication from this which is somewhat philosophical but also pragmatic: this absolute nothingness was imbued with the law of energy conservation. The nothingness then could be said to have some sort of mathematical adherence; this in itself could be considered to be a property and so the pre-universal state wasn’t necessarily absolute nothingness. One could progress and ask how far do we have to go reach a point where there was absolute nothingness; does such a thing exist? Maybe this mathematical adherence is fundamental to anything that could be considered a state of pre-universal nothingness. However there is one thing which is more grounded and that is to say that since the universe sprung from this “nothingness” which possesses laws the nothingness could be said to be some sort of extra-universal plane-just a description nothing inexplicably profound-which the universe exists within even now.

I would also like to expound a conceptual idea of mine that takes a different stance to the one which conceives time as always flowing. The idea is simply that space-time is static and we experience times slices through it as moments. We can say that constant motion through time is required in order for us to perceive-without motion through time there would be no perception. So we are 4 dimensional structures in space-time and each three dimensional slice of constant time is the “present” and moving through these slices generates our perceptions. A side note here would be this is not as depressing as it sounds; these structures (us) are still self-influencing and influence their own future. So in a sense our perceptions and time are running in tandem by necessity.
