What Happens If A Giant Star Replaces Our Sun? 🔥 (Simulation)

What would happen if we replaced our Sun with the most colossal and terrifying monsters in space? In this video, we're taking an extreme journey through the cosmos using Universe Sandbox! We'll work our way up from our own home star and the bright Sirius, all the way to massive red hypergiants like Betelgeuse, UY Scuti, and the absolute record-holder — Stephenson 2-18. You'll see with your own eyes how the crushing gravity and scorching plasma of these titans annihilate planets, boil away oceans, and completely swallow the Solar System. The sheer scale of these stars will absolutely blow your mind! 👇 CHALLENGE ME IN THE COMMENTS! 👇 Which of these stars terrified you the most?
