Universe is very big and it’s expanding continuously
In night sky, we see countless stars , which are part of beautiful Milky Way , but in front of our galaxy, in this big universe, around 2 lakh crore galaxies are there
In starting, while looking at galaxies, it seems that they are spread like butterflies, slowly we got to know, that they make a large web
This cosmic web is the structure, which joints all the areas of universe , if you don’t know about cosmic web , you don’t know anything about universe
Cosmic web joints the galaxies, it is the creater of the universe , and the future of universe depends on it , cosmic web is our universe most essential part
Without cosmic web , no stars can be made, nor planets and not the universe itself , how this universe from a gas shell becomes a cosmic web, in which galaxies, planets and we live
First time when we look at the galaxies, we thought they are spread unevenly, but they are proper planned in the cosmic web
How this web was born , it is the greatest mystery of cosmos,
Chile , 2021 , scientists with VLT (very large telescope ) looks in Hubble deep field, which is a very famous point of universe
This was discovered by Hubble telescope in 1995 , , it has thousands of galaxies in it , this is very small part of cosmic web
Cosmic web is made of hydrogen gases , which is spread in the whole universe, and it joins all galaxies , in the joint of cosmic web , there are galaxies, gases , these galaxies look like highways between big cities , this cosmic web was made in the starting of universe

In the starting universe was a big gas ball , then a big explosion happened, and universe becomes cold , and the small particles were made , smaller than nucleus, the energy was so intense, that gravity was not working , gravity was working on dark matter
In the starting of universe, 85% was dark matter, in the starting of universe, both matter and dark matter was there , but their behaviour was different
Universe was so hot in the starting, that matter particles can’t stay with each other, but dark matter has other properties, the radiation was acting on dark matter in a different way , because it was becoming cool , and the particle of dark matter were coming closer to each other
Dark matter becomes big , and the gravity produced by it , starts making shadows like thing , after 3 lakh 80 thousand years after the Big Bang , the energy cools down, and matter particles speed reduced, protons and electrons jointly started to make helium and dark matter gravity started working on matter
After some time, in the whole universe, matter starting to accumulate, and galaxies started to build, dark matter starting to pull the gases , by which in future, cosmic web was made , and galaxies were made , it took a lot of time to happen
The dark matter was making cosmic web and galaxies, because dark matter was too much, it seems that cosmic web is made of dark matter , as cosmic web started to become big , it started to pull more dark matter, dark matter by squeezing started to make thread like strings
Those thread like strings started to join those areas , where there was more dark matter, by which the foundation of dark matter started pulling more gases , hydrogen gases starting to join cosmic web
For crores of year it happened, and the biggest star were born with a great explosion, in 2018 , scientists were looking at a old galaxy, they see the oldest star in that galaxy, this galaxy were very big , because big stars began to form , from that stars . We can tell how cosmic web was made from galaxies and stars
