• Stars BIGGER than our Sun have unique life stories.
• They're called main sequence stars, and guess what? They're scorching hot! 🔥 Why? Because they're so MASSIVE!

Example: Imagine a small firecracker vs. a massive dynamite. The dynamite has way more explosive material, so it gives a louder BOOM! Similarly, bigger stars burn hotter.

• When these big stars age, they evolve into red giants.
• Here's the fun bit: these red giants have layers like onions!
  • The core has the heaviest elements (imagine a dense onion center).
  • As you move outward, elements get lighter.

• Stars have a balance: gravity pulling in and internal pressures pushing out.
• As massive stars get older, gravity starts winning, making stars contract.
• But wait! Electrons in the star fight back, creating a pressure called electron degeneracy pressure.
• Problem: For these massive stars, stability can't last. Drama Alert!

• This is like the weight limit for a cosmic elevator.
• Stars with a remnant mass over 1.4 times our Sun can't become a white dwarf.
• Imagine trying to stuff 10 elephants into a mini-van. It won't work! Similarly, massive stars can't fit into the "white dwarf category."

Real-world Side Story: This limit is named after a genius, Subrahmanyan Chandrasekhar. At just 24, he proposed a groundbreaking idea. Sir Arthur Eddington, a big-shot in astrophysics, disagreed. But Chandrasekhar, resilient as ever, persisted, and guess what? He was RIGHT! (And got a Nobel Prize in 1983 to prove it!)
