Scientists are creating a ‘time machine’ simulation to observe how ‘ancient galaxy cities’ formed

ASTROPHYSICS have developed a “time machine” simulation that allows them to watch the formation of distant “galaxy cities”.
The simulations can reconstruct the life cycle of galaxies observed in the distant Universe 11 billion years ago, a new study shows.

Processes in space can take a long time on Earth, making them difficult to study, SciTechDaily reported.
Additionally, when astrophysicists study celestial bodies 10 billion light-years away, they perceive the object as if we were seeing it 10 billion years ago.
Knowing this, researchers would look at galaxies at different distances and compare the differences in their life cycles.
A team of researchers came together to find a solution for viewing distant galaxies as they wanted to analyze more phases than could be perceived in real time.


“We wanted to try to develop a full simulation of the real distant Universe to see how structures started and how they ended,” Metin Ata said.
Ata is part of a group led by the Kavli Institute that wanted to learn more about these distant galaxies, since they are essentially ancestors of modern-day galaxy clusters.
Their solution was Constrained Simulations of the Cosmos Field or COSTCO.
Project assistant Professor Khee-Gan Lee said this invention is like building a time machine.
“It’s like finding an old black and white picture of your grandfather and making a video of his life,” Lee said of the snapshots of distant galaxy clusters.
Using these ancient “black-and-white” images, the researchers created a video in which they fast-forward the age of galaxy clusters to show how they would form.
A video shows the results of this research in action.
Using these simulations, the researchers were able to predict the ultimate mass and distribution of structures in a given space.


This allowed researchers to uncover previously undiscovered discrepancies in our current understanding of the universe, SciTechDaily reported.
Their work is also applied to other projects such as studying the cosmological environment of galaxies.
