Effects of Sun's Disappearance

The video explores the hypothetical scenario of the Sun disappearing. Initially, Earth would not notice for 8.5 minutes due to the time it takes for light to travel. Gravity, like light, would also take time to affect Earth, causing it to drift into space. Without the Sun, temperatures would plummet, and life would struggle to survive. Plants would die without photosynthesis, disrupting the food chain. While most life would perish, organisms near geothermal vents could survive indefinitely. The video highlights the Sun's crucial role in sustaining life and the potential consequences of its absence.
