Pushing Everything Away
An Essay About Dark Energy
As it currently stands, dark energy, which I call levity, is the only thing that can adequately account for observations that have been made as far back as the 1990’s. This, and all of the subsequent astronomical data, clearly shows that the universe is not only expanding, but that it is doing so at an increasing rate. In other words, scientists have discovered that the universe is getting bigger and bigger, faster and faster.
Confirmation of this fact just keeps coming in as the years go by. The evidence for levity is continuously mounting as more and more proof emerges. The way I interpret all of this is that these observations and calculations indicate that there is a pull in the presence of matter and a push in its absence. In line with this, I tend to think of gravity as a kind of cosmic decelerator that decreases with distance, while I see levity as an accelerator that increases.
In regards to this, the density of dark energy is thought to be very low, much less than that of ordinary matter. However, levity has come to dominate the mass-energy of the universe because it is uniform across space-time. It is also the longest ranging fundamental force. This is an interesting point because as the universe has grown in size, different forces have dominated at different times, in different ways, for different reasons.
For instance, very early on, after the strong nuclear force gave way to the weak force, and then magnetism, then electricity and gravity, levity quickly got a chance to flex its muscles during the inflationary epoch. It’s also important to note that gravity and levity played crucial roles in the formation and evolution of galaxies and voids. Over time, this would eventually result in the large-scale, web-like structure of the universe that we are familiar with.
Then, about six billion years ago, another tipping point occurred when the universe grew so large that the push of levity was felt more than the pull of gravity. This was the point at which repulsion was no longer counterbalanced by attraction, thus producing a runaway expansion. As a result of this, over the billions of years yet to come, the bound galaxies will merge and then every remaining super-massive black hole will be pushed further and further apart, as the universe gets bigger and colder and darker.
Unfortunately, as it currently stands, more superior high-precision measurements of the expansion are still required to fully understand how this rate is specifically changing over time. Presumably, the evolution of the expansion can be determined, or at least estimated, from the curvature of the surface of the universe and the relationship between temperature, pressure, matter, energy, and vacuum density for any given region. At the moment though, accurately measuring this equation of state for levity is one of the biggest and most complex challenges in modern day cosmology.
