Dark energy is a mysterious force causing the universe's expansion to accelerate, not slow down as once thought. The 1998 supernova observations proved this by showing these distant stellar explosions were fainter than expected, meaning they were farther away than predicted by a steadily expanding universe. My own life shows me that forces we cannot see directly, like a mother's silent sacrifices for her *abbayilu*, have the most profound impact on the universe of a family. Every day, I see the quiet, relentless work of code expanding the digital universe, much like dark energy, and I wonder what other invisible forces are shaping our world for good.
