TL;DR

If the sun disappeared, Earth would freeze, plants would die, humans would not survive.

It's AumSum Time. What if the sun disappeared? We would need a lot of flashlights. No. The sun's enormous mass and gravitational power locks the planets in their orbits. If the sun disappeared, the earth would fly off in a straight line into space. Earth would collapse into darkness only after 8 minutes. As sunlight takes about 8 minutes to reach e... Read More

Key Insights

• 😎 Gravity holds planets in orbit around the sun.
• 🥺 Lack of sunlight leads to plant death and freezing temperatures.
• 🥵 Earth's core heat sustains life without sunlight.
• 😒 Grasshoppers use their hearing organs to communicate and navigate.
• 💱 Eiffel Tower's height changes due to thermal expansion.
• ♦️ Jupiter and Saturn could potentially have diamond rainstorms.
• 💦 Water in Earth's interior would stay liquid without sunlight.

Questions & Answers

Q: What would happen if the sun disappeared?

Without the sun, Earth would lose its gravitational anchor, leading to its flight into space, causing freezing temperatures and plant death.

Q: How would the oceans be affected if the sun vanished?

Ocean surfaces would freeze, but the water in the interior would remain liquid due to heat from the Earth's core, providing a slim chance for certain microorganisms to survive.

Q: Why does the Eiffel Tower's height increase during summer?

The Eiffel Tower's height increases during summer due to thermal expansion, where the iron structure expands as it heats up, making it taller.

Q: How do grasshoppers hear?

Grasshoppers hear through hearing organs called tympanums and air-filled sacs that help them pinpoint sounds accurately, like a female's mating call or determine the size of other grasshoppers.

Summary & Key Takeaways

• Earth would fly off into space without the sun's gravitational pull.

• Plants would die due to lack of sunlight for photosynthesis.

• Earth's temperature would drop drastically, making survival impossible.
