50 Million Light Years Long Galactic Filament Spotted

Ever wonder how we came into existence? The Big Bang is always the first thing that comes to the mind of any person. However, many always discard this theory due to the limited amount of evidence that is present with us. But the astronomers from Germany have presented a new set of evidence in the favour of the Big Bang. Their findings were published in the science journal: Astronomy & Astrophysics, in which it is shown that a new 50 million light-years long inter-galactic filament came into the light.

The Birth of the Universe

After the Big Bang, almost all the density was uniformly distributed, but the sections that had a higher density of gases had greater gravitational force. These parts of the greater gravitational force lead to the formation of the cosmic bodies that we know as of today. This pulling of the gas particles to each other to clump together leads to the space between the greater gravitational forces becoming emptier and emptier. These bodies formed from the gases’ clusters come under the influence of each other to form galaxies. These galaxies later develop something called galaxy clusters.

The Filament Hypothesis

If we assume that the universe came into its known existence as stated above, then the galaxy clusters must be separated with some remnants of the gases that must have not come under any influence of gravity of the other gases’ clusters. These left-out gas particles then must have formed something like a lightning strike structure.

The Findings

The above hypothesis was proven correct by Prof. Dr. Thomas Reiprich and his acquaintances from the Argelander Institute for Astronomy at the University of Bonn. These filaments are present between galaxies which differentiate their territory. The filaments are made up of gases that are the result of the Big Bang. Also, filaments don’t have uniform density throughout their volume. Some places have a greater density of gases and some don’t.



The Characteristics of the Filaments

However, these gas densities in the filaments are of the order of 10 particles per cubic meter. This density is so low that it surpasses the best vacuum condition ever created on our planet. This low density is due to the immense scale of the Big Bang and the galaxy clusters.

To detect this filament would have been impossible if it would not have been an eROSITA space telescope. The eROSITA has a very set of extremely sensitive sensors that respond to the X-ray emitted by the gas filaments. This telescope has a large field of view due to the wide-angle lens. This level of aperture allows it to capture a big chunk of the sky in great resolution too. This is the reason why the astronomers were able to take a detailed picture of the filaments in a relatively short amount of time.

Another Hunch

A computer simulation backed up the findings. The findings were the same as the computer simulation that was made in order to support the hypothesis. Also, it is believed by many astronomers that we are not yet capable of detecting all the matter in the universe and the filaments are the answer to that. The astronomers have a hunch that, these filaments actually hide the missing matter in their spread put volume.
