This is a challenge that faces astronomers who study dark matter. Although dark matter comprises 85% of all matter in the universe, it doesn’t interact with light. It can only be seen through the gravitational influence it has on light and other matter.
To make matters worse that research efforts to directly detect dark matter on Earth have been unsuccessful so far.
Using a simulation of the universe, Harvard researchers found that dark matter seems to have a universal property: It forms halos.
This new simulation, according to Nature (Nature 585.7823, 2020, 39-42) reveals what dark matter might look like if we could see it: massive halos surrounding every galaxy in the universe.
... but also every living being have own halos. I can see it, it's a universal fractal. This is also called chi, and it has measurable mass.
Using a simulation of the universe, Harvard researchers found the result, which is a visual representation of how dark matter is distributed across the universe, a pattern known as like a som cosmic web.
It shows how dark matter clusters together in halos connected by long filaments, as shown in the image below. Scientists think gas gets funneled along these filaments into the dense centers of the halos, where it collects, eventually forming stars and galaxies.
We can think about this web is like cars taking highways to cities.
