The reasoning behind building a 3D map of the universe is to enable scientists to learn more about dark energy an unknown form of energy that is said to be the cause of the accelerating rate of expansion of the universe. But why is it so important? Well, more knowledge of dark energy could challenge our understanding of gravity, perhaps into a theory that no one has even thought about, leading scientists to also question the Big Bang, from the birth of the universe, how it's aged, and how it will be ultimately destroyed. It's clear that dark energy is something that needs to be understood as it leads to question science we have all grown up learning about. Perlmutter can also benefit material science laying the way for advances in batteries and biofuels. Also, applications like the Quantum Espresso (an integrated suite of Open-Source computer codes for electronic-structure calculations and materials modelling at the nanoscale) can take advantage of Perlmutter's traditional simulation and machine learning capabilities, which will enables scientists to study more atoms over a longer time period.
