Ordinary matter makes up just 5% of the cosmos. The remaining 95% belongs to an unseen realm governed by dark matter and dark energy. Dark matter binds galaxies through gravity, while dark energy drives their acceleration apart. They shape our cosmic structure, yet their true natures remain enigmatic. Scientists believe these forces may seal the fate of our cosmos, a big crunch from dark matter's gravitational pull or a cold, empty void from dark energy's repulsion. Can a new frontier of research unlock the secrets of this shadowy domain and its implications for our future?
