Discovered in the late 1990s, dark energy is a mysterious force acting against gravity. It is responsible for the accelerated expansion of the universe, pushing galaxies away from each other at ever-increasing speeds. 3. The Geometry of Space cosmology
Some of the most exciting areas of research in cosmology today include: ΛCDM rests on three observational legs that have
If dark energy becomes strong enough, it could eventually tear apart galaxies, stars, and even atoms themselves. it could eventually tear apart galaxies
