In 4 billion years, this head-on collision will reshape our entire night sky. The craziest part? The stars are so far apart that they will likely pass right through each other without hitting! 🤯 Is this the end or a new beginning? 👇 Credits: Visualization: Frank Summers (STScI) Simulation: G.

Sounds destructive, right? Surprisingly, stars won’t smash into each other. Space is mostly empty — gravity does the real damage. In the end, both galaxies may merge into one giant galaxy: “Milkomeda.” The universe isn’t calm. It’s constantly evolving, colliding, and rebuil
