Exploring the Mysterious Nature of Dark Matter and Energy
05:54 - 11:40 (05:45)
The presence of dark matter and energy exerts a strong gravitational force despite being invisible, which is crucial in holding galaxies together in the universe, and while scientists haven't found evidence for it yet, they are constantly working on new experiments to observe and understand its nature.

Summary
During the Big Bang, there were almost equal amounts of matter and antimatter. However, the ratio was one million to one million and one, with the excess matter being the only one left in the universe, which is a puzzle in physics along with the imbalance between matter and antimatter.
