Africa-Press – Mauritius. Light from the galaxies the research team set their sights on travelled a distance of some 11 billion light-years to reach our planet. A team of researchers led by Kavli Institute for the Physics and Mathematics of the Universe Project researcher Metin Ata and Project Assistant Professor Khee-Gan Lee has managed to produce simulations that recreate full life cycles of whole collections of galaxies observed some 11 billion years ago, SciTechDaily reports.
According to the media outlet, the team sought to gain insight into massive galaxy protoclusters, the ancestors of existing galaxy clusters, but discovered that existing studies of these distant structures were done with simple models rather than with simulations.
As it takes light from the galaxies the researchers were focusing on some 11 billion light-years to reach Earth, Lee compared the development of the simulation to building a time machine.
“It’s like finding an old black-and-white picture of your grandfather and creating a video of his life”, he said.
The researchers essentially took “snapshots” of those “young grandparent galaxies”, as the media outlet put it, and then fast-forwarded their age to examine the process of galaxy clusters’ formation.
