2 GALAXYS CLASH TOGETHER

[00:00:00]What happens when two entire galaxies [music] crash into each other?

[00:00:05]The answer is breathtaking and terrifying. [music] Galaxies are not solid objects. They are vast collections [music] of billions of stars, gas, and dust. Despite their enormous size, most of a galaxy is actually empty space [music] between stars. When two galaxies collide, individual stars rarely crash directly into one another. Instead, powerful gravitational [music] forces pull and stretch both galaxies into wild, beautiful new shapes. Long tidal tails [music] of stars get flung outward, creating spectacular cosmic bridges between the two galaxies.

[00:00:43]Massive clouds of gas collide violently, triggering explosive bursts of new star formation in both galaxies.

[00:00:51]These starburst regions glow intensely, outshining entire galaxies with their raw, explosive [music] stellar energy.

[00:00:59]At the center of most galaxies, lurks a super massive black hole waiting silently in the dark. When galaxies merge, >> [music] >> their black holes will spiral toward each other in a deadly gravitational dance. Eventually, they merge [music] into one colossal black hole, releasing unimaginable energy across the entire universe. Our own Milky Way will collide with Andromeda in 4 billion years.

[00:01:27]The universe never stops evolving.
