Let's dive deep into the Multiverse

Hey hi, soo this is my little astronomy corner. Buckle up while i take you on a ride trough our -well everything- and all the tunnels and connections science is beginning to grasp, so we can start grasping and gasping.
I love to go to every obserbvatory i can find and to inform myself and learn more about the universe every day. I will probably post articles and papers i find interesting, as well as some facts for funsies. And LOTS of resorces i enjoy. I hope you do as well and we can create a grid of connected information about our little star cluster bubble universe.

Mapping the Dark Matter

All galaxies are made up of stars, gas, dust, and dark matter, which are bound together by gravity. The Bullet Cluster is made up of two very massive collections of galaxies, known as galaxy clusters, that are themselves bound by gravity.
These galaxy clusters act as gravitational lenses, magnifying the light of background galaxies. “Gravitational lensing allows us to infer the distribution of dark matter,” said James Jee, a co-author, professor at Yonsei University, and research associate at UC Davis in California.

To visualize gravitational lensing and dark matter, think of a pond filled with clear water and pebbles. “You cannot see the water unless there is wind, which causes ripples,” Jee explained. “Those ripples distort the shapes of the pebbles below, causing the water to act like a lens.” The same thing happens in space, but the water is dark matter and the pebbles are background galaxies.
