Understanding Dark Matter and Dark Energy

Dark matter and dark energy remain intriguing mysteries in the universe, with dark matter likely being a particle that hasn't been discovered yet. Despite not finding it yet, experiments are ongoing to unravel its secrets. On the other hand, dark energy is thought to be related to Einstein's cosmological constant, which implies energy existing in empty space, pushing the universe apart. Recent research suggests that dark energy might be slowly declining, posing an exciting challenge for further exploration.
