What Happens When the Sun Disappears?

The video explores the critical role of the sun in sustaining life on Earth and examines the hypothetical scenario of its sudden disappearance. Initially, there would be no immediate change for eight minutes due to the time light takes to reach Earth. However, darkness would soon envelop the planet, and Earth's orbit would be disrupted, sending it into space. Photosynthesis would cease, leading to plant death, and temperatures would plummet, threatening most life forms. Oceans would eventually freeze, but deep-sea organisms might survive for billions of years. The video concludes with a reminder of the sun's finite lifespan, emphasizing its importance.

• The importance of the Moon

• The formation of the solar system
