If people lived here, it was not until the 1960s that we could see other galaxies in the universe.
The universe consists of many galaxies, sources of knowledge that we may never understand.
Findings from more than a century ago about neighboring spiral and elliptical galaxies show that Milky Way is not alone.
Even astronomers from ancient times can observe bright telescopes with telescopes.
By measuring the speed and distance of these galaxies, humans discover the universe is expanding.The observed redshift from galaxies grows with time that light needs to return to Earth.
Without nearby galaxies, we can never understand the origin of the universe born from Big Bang.The data available today, including observations of nearby galaxies and cosmic microwaves show that the Big Bang is the most plausible explanation.As the universe expands, it also cools, enabling ions, neutral atoms, molecules, gas clouds, stars and finally galaxies to form.
Dark matter streams sometimes separate galaxies away and collect them into clusters as in this simulation.
Most galaxies will clump together in groups, clusters or along the spatial structure fibers, while others will be 'material deprived' .The illustration shows the distribution of matter in the areas of the Milky Way, where there is a very dense place but there are places where there is nothing.
However, in extremely deprived areas, galaxies still occasionally form.
This is MCG + 01-02-015 , considered the most lonely galaxy in the visible universe.
From this galaxy in all directions, no other galaxy will be found within 100 million light-years.Around it are great cosmic spaces, which can last up to hundreds of millions of light years.The gap contains MCG + 01-02-015 especially because the material density is too low, there is only one galaxy known by humans.However, there may be small ultra-low-brightness galaxies that exist in this area.
If we live there, old scientists' telescopes will not be able to observe other galaxies, and must wait until the 1960s, when Italian astronomers Paolo Maffei discovered the method of interest. Observe the galaxy by infrared .
This is probably human luck: The position in the universe allows us to understand it .The different galaxies of the Virgo mob gather together.This illustration shows other galaxies near us.If this is the MCG + 01-02-015 galaxy, it will be just a black picture.
