The Dark Mystery of Galaxy X

The video explores the mysterious nature of dark matter, which makes up 96% of the universe. It discusses the discovery of Galaxy X, a potential dark matter galaxy, and the research efforts to confirm its existence. By studying the gravitational effects and visible matter like Cepheid variables, astronomers aim to uncover more about dark matter galaxies. The video concludes with a call for support to continue such research.
