What Would Happen If the Sun Suddenly Stopped Burning?

💡 The Answer

• The Sun would immediately begin to cool, but the process takes millions of years.
• Earth would plunge into darkness within about 8 minutes due to light travel time.
• Without fusion pressure, gravity would cause the Sun to collapse into a white dwarf.
• Photosynthesis would cease, collapsing the food chain and eventually freezing Earth.
• The solar system would drift without the Sun's gravitational anchor? Actually gravity persists.
