[00:00:01]Season 1 episode 5.

[00:00:04]Dark matter explained in today's episode. We are exploring dark matter, the invisible substance that helps hold galaxies together and remains one of the greatest mysteries in the universe.

[00:00:16]Scientists discovered that galaxies rotate much faster than expected.

[00:00:22]According to normal physics, galaxies should fly apart because there is not enough visible matter to hold them together.

[00:00:29]This mystery led to the discovery of dark matter. Dark matter is an invisible form of matter that does not emit, reflect, or absorb light. Although it cannot be seen directly, scientists know it exists because of its gravitational effects on galaxies and stars.

[00:00:47]Researchers estimate that dark matter makes up about 27% of the universe, while normal matter, including stars, planets, and humans, makes up only around 5%.

[00:01:00]Dark matter acts like a hidden cosmic framework that helps galaxies form and remain stable.

[00:01:07]Without it, the structure of the universe would be completely different.

[00:01:11]Scientists continue searching for answers using advanced observatories and experiments around the world.

[00:01:18]Telescopes, such as the James Webb Space Telescope, are helping researchers study galaxy formation to better understand the influence of dark matter. Even today, dark matter remains one of the greatest mysteries in modern astronomy.

[00:01:35]In the next episode, we will explore dark energy and discover why the universe is expanding faster every second. If you enjoyed this video, do like, share, and subscribe for more space facts.
