Is is correct to understand time as the ongoing expansion of space since it first emerged at the Big Bang. Is it correct to see the expansion of spacetime as co-emerging with the release of light at the time when the universe became transparent? Does light (the speed of which) determines the rate of expansion of spacetime? It seems to me that light and spacetime is closely determined by eachother, or even co-dependent on each other? Or could even be considered to be of one unit; the emergence of light = spacetime? Another great interest of mine lies in the phenomenon that the expansion of spacetime emerges from each and every point in space continuously at every instance; now, now and now. Is this a correct view to hold? Based on Buddhist scriptures the Buddha spoke of instantaneous arising of this event, happening in an unbelievable speed. I myself have had a glimpse through a spiritual experience of this enormous velocity. I call it real time; the time spacetime emerges anew in each instance. We never get to experience this real speed of the universe as we are used to regular intervals of the sun and moon. But sometimes, through extraordinary deeper insights we may have glimpses of the real state of affairs. I have had a vision of reaching back till the very origin of the Big Bang 13.7 billion years ago. This made it clear to me what is meant by deep time, just as astronomers are beholding the origin of the universe by looking into space. As layers upon layers, new spacetime is continuously overlaying and replacing "old" spacetime, making the universe we see today completly a new universe compared to yesterdays. So the slowness of time being the only way to be able to see things of the past. In Buddhist scriptures it's also spoken about the co-extensive emergence of the void with emptiness. This I can relate to the link between the co-emergence of spacetime with the expansion of light. What do you think? And once all light is gone in the end of the universe era there can not be said that spacetime still exist; they are co-dependant. Sincerely, Bjorn Saw London, UK Motion of time.

I do not have the academic background to understand exactly what you mean but it resonates with my own understanding. Singularity especially. Are you speaking about what propels the universe's expansion, and/or of the force that will make dark energy obsolete? I enjoy the theory of the singularity that is located in all and every point in space, and as such being the "place" in which a black hole collapses, and at the same time being that place of origin where from the Big Bang emerged 13.7 billion years ago. Together with the understanding of the ever continuous emergence of spacetime from that very source, as layers upon layers in breathtaking velocity. Light being the expression and the creation and the vehicle of spacetime, that propels the expansion of the universe. Dear Colin,

If you accept that at some point when a black hole forms and becomes a singularity the laws of space and time become meaningless then if you have a supermassive black hole one side of the universe and over the other side you have another then at some point in the collapse on each one the laws will break down. This means the conditions become identical and with space and time out of the picture the two points snap together. Therefore you can have any number of black holes but one and only one singularity. From the above everything else falls in to place. Dark energy is replaced by leverage - the side of the supermassive black hole, immediately above the singularity point, closest to the next one will collapse (and be compressed) through the point fractionally earlier than the opposite side (which will be stretched). Thus the black holes will move away from each other taking their galaxies with them. The driving force being the matter falling in to the (one and only singularity). If you accept the single singularity then it must lie at the centre of the universe. As the supermassive black holes snap to the singularity then the matter pouring in has to pass through all that lies between although because space is no longer meaningful there is no distance at all. Therefore the singularity occupies a point at the centre of the universe at the same time as occupying all points between. Spread the mass of the singularity across the universe and you have a week force somewhat like gravity. There is more but I don't know how much this post will take before it collapses into a black hole of its own! There is no such thing as dark energy – it is all leverage.

A pattern seems to be emerging: gamma-ray bursts are extragalactic events occurring far, far away.
