What is the intergalactic medium?
The intergalactic medium (IgM) is a thin gas that extends between the galaxies of the universe. It occupies the cosmic fiber structure, with thin Wisps and walls separating huge emptiness. The intergalactic medium combines galaxies together as Connect-the-Te-Tets.
The intergalactic medium is quadrillions earlier than the so -called thin air. Scientists estimate the average density of the universe as a whole as about one hydrogen atom for a cubic meter, with an intergalactic medium having about 10 to 100 atoms per cubic meter. If you want to put it in the perspective: if you have collected all the matter from the volume of the intergalactic medium about as large as the Earth, you would end up with a mass equal to a small ball deposit.
Most of the universe is also quite cold: 2.73 Kelvin. This heat is the rest of the Big Bang. The intergalactic medium is also filled with a highly homogeneous spectrum of radiation called space microwave background.
Intergalactic medium, a fibrous structure between galaxies, is much warmer than the average temperature of the universe: the order of 100 to 10 million Kelvin. This is because the gas is heated when it falls into the intermediate medium of the huge cavities that surround it. This temperature is sufficient for ionization or undressing of electrons from the core, so the main component of the intergalactic medium is ionized hydrogen. Physicists call it a warm intergalactic medium. In some areas near the intersections of space fibers, the gas temperature is close to 100 million Kelvin. Even though it sounds like a lot, it wouldn't be very hot if you were standing in it, because the atoms that make it are so thin.
The particularly condensed area of the intergalactic medium is known as an intracluster medium, beprotože lies in the middle of the Galaxy clusters. The Medium Intracluster emits X -rays that can be observed using a telescope.
Because the universe expands at speeding speed, the whole thing alternates over time. In the end, perhaps in a few hundred billion years or maybe longer, it will spread so quickly that our galaxy and everything will be completely torn in it.
