Big Mysteries of the Universe: Dark Energy and Dark Matter
The podcast delves into three significant mysteries of the universe. Firstly, dark energy, constituting 74% of the universe's energy content, continues to stretch the universe at an accelerating rate, a phenomenon known but not understood. Secondly, dark matter, comprising 85% of all matter, remains an enigma, with its presence inferred solely through astrophysical observations. Lastly, the matter-antimatter asymmetry puzzles scientists as the absence of antimatter defies the equal creation theory.
