22 : Cosmic Collisions Online

We wouldn’t be here without a massive crash. About 4.5 billion years ago, a Mars-sized object named slammed into a young Earth. The debris from this cataclysmic impact eventually clumped together to form the Moon . This collision didn’t just give us a nightlight; it stabilized Earth’s tilt, giving us predictable seasons and a environment stable enough for life to evolve. 2. Galactic Cannibalism

Cosmic collisions represent the ultimate paradox: they are forces of absolute destruction that act as the primary drivers of creation. They build moons, birth stars, and deliver the heavy elements necessary for technology and life. 22 : Cosmic Collisions

Galaxies don’t just float past each other; they eat each other. Our own is currently in the process of "shredding" smaller satellite galaxies like the Sagittarius Dwarf. We wouldn’t be here without a massive crash

But the main event is still to come. In about 4 billion years, we are on a head-on collision course with the . While "collision" sounds scary, galaxies are mostly empty space, so individual stars likely won't hit each other. Instead, the two will perform a slow, gravitational ballet, eventually merging into one giant elliptical galaxy nicknamed "Milkomeda." 3. Creating the Elements of Bling This collision didn’t just give us a nightlight;
