Dark Matter and Dark Energy: The Frontier of Astronomy

The video explores the mysteries of dark matter and dark energy in the universe. It explains how dark matter, which does not emit light, is detected through its gravitational effects on galaxies. The concept of gravitational lensing is introduced as evidence for dark matter. Potential candidates for dark matter particles, such as WIMPs, are discussed. The video also delves into dark energy, a force causing the universe's accelerated expansion, and considers Einstein's cosmological constant as a possible explanation. The video highlights the collaboration between astronomers and physicists to solve these cosmic puzzles.
