If the Sun were to suddenly disappear, the effects on Earth would be catastrophic. Within a few minutes, the planet would be plunged into darkness, and the temperature would begin to drop rapidly. The loss of sunlight would disrupt the food chain, causing widespread famine and death among plants and animals.
In the first 24 hours, panic and social upheaval would ensue, with widespread looting and rioting. Governments would struggle to maintain control, and martial law might be implemented. As the days passed, the cold would become unbearable, and the majority of the population would succumb to hypothermia, starvation, or violence.
The only chance for survival would be to build an artificial, temperature-controlled habitat, such as an underground bunker or an underwater habitat near geothermal vents. This would require a cooperative community, sustainable food sources, breathable air systems, and artificial light.
The video suggests that if prepared ahead of time, it might be possible to sustain the human race by creating a self-sufficient underground society. However, the majority of humanity would likely perish within a week of the Sun's disappearance.
Here are the key facts extracted from the text:
1. The Sun is approximately 93 million miles away from Earth.
2. The surface temperature of the Sun is around 5,800 degrees Kelvin.
3. The Sun's rays take about 8.5 minutes to reach the Earth.
4. If the Sun were to suddenly disappear, the Earth would not immediately go dark, as the last of the Sun's rays would still be on their way to our planet.
5. The Earth's average surface temperature would drop to 32 degrees Fahrenheit within a week of the Sun vanishing.
6. Within a year, the temperature would drop to -150 degrees Fahrenheit.
7. The Earth would eventually become an ice planet if the Sun were to disappear.
8. Rivers, lakes, and oceans would freeze on the surface, while the water underneath would remain liquid for thousands of years.
9. Crops and most plant life would rapidly die without the Sun.
10. Photosynthesis would immediately cease, and most plants would be dead within a few weeks.
11. Large, healthy trees could possibly survive for several decades without photosynthesis.
12. Herbivores would quickly die off, followed by carnivores and scavengers.
13. If the Sun were to suddenly vanish, it would disrupt the orbits of the heavenly bodies in our solar system.
14. The Sun's gravitational mass controls the orbit of everything in our solar system.
15. If the Sun were to disappear, the Earth would move toward distant stars at 67,000 miles per hour.
16. The Earth could potentially get caught in the gravitational pull of another star and begin orbiting it.
17. This process would take several thousand years.
18. The atmosphere would begin to separate into its component gases by density.
19. The higher-density elements would drift to the ground level, and the lower-density gases would rise.
20. This would disrupt the amount of breathable air available.
21. The temperature would drop rapidly, and the poles of the Earth would cool.
22. The overall atmospheric height would begin to drop as density grew.
23. Strong winds would begin to blow toward the equator, and the water vapor in the atmosphere would condense and snow.
24. Many places would be hit with blizzards, and the weather would be wild and cold.
25. Geothermal temperature rises about one degree for every 70 feet of depth in most parts of the world.
26. If you were able to create a habitat roughly a mile underground, you could live at a temperature of around 75.5 degrees Fahrenheit.
27. To survive, you would need to rapidly build an artificial, temperature-controlled habitat to live in.
28. The best bet would be to burrow into the earth and live deep underground, away from tectonic plate boundaries.
29. Another option might be to build a habitat underwater and near geothermal vents.
30. Iceland would have a head start using geothermal energy to heat your habitat.
