The video discusses 10 interesting questions with surprising answers. The topics include:
1. What do babies dream about? They dream about sensory stimuli they've experienced, such as the taste of breast milk or the feeling of being wrapped in their parents' arms.
2. What happens to fat when we lose weight? Most of it is exhaled through the lungs, with the rest being converted into liquid and excreted through urine, sweat, and tears.
3. Why do people get dizzy in cars? It's due to conflicting signals between the senses, including the inner ear, eyes, and extremities, which can confuse the brain.
4. Why can't people remember things from when they were babies? It's because the hippocampus, responsible for storing long-term memories, is still developing and producing new neurons at a high rate, making it hard for memories to stick.
5. Why do people forget their dreams? It's because the hippocampus, which stores memories, is not synchronized with other parts of the brain during sleep, making it hard to recall dreams.
6. What is the largest number a person has counted to? Jeremy Harner holds the Guinness record for counting from 1 to 1 million, taking 88 days.
7. How much would the Earth be worth if it had a price? A physicist created an equation that estimated the Earth's value to be between $4 and $6 quadrillion.
8. What happens to deleted files on a computer? They are not actually deleted but rather become inaccessible, and the space they occupied is eventually overwritten by new files.
9. How many megapixels does the human eye have? It's estimated to be around 576 megapixels, making it more complex than any current camera.

Here are the key facts extracted from the text:
1. Babies dream about sensory stimuli they already know, such as the taste of breast milk or the feeling of being wrapped in their parents' arms.
2. Babies start dreaming about more complex things that make sense around 18 months old.
3. 84% of fat lost by the body is exhaled through the lungs as carbon dioxide.
4. The rest of the fat lost is converted into liquid that is excreted through urine, sweat, tears, and other body fluids.
5. Fish drink water to live, regardless of whether they are freshwater or saltwater fish.
6. Fish bodies are made up of various substances, including sugars, proteins, fats, water, and dissolved salts.
7. Fish must keep the salts inside their body at an optimal level to survive.
8. Most humans can't remember things that happened to them before they were 4 or 5 years old.
9. The hippocampus is the part of the brain responsible for storing long-term memories.
10. The hippocampus is also the only place in the brain where new neurons are made.
11. During sleep, the synchronization between the hippocampus and other parts of the brain disappears, making it harder to remember dreams.
12. Jeremy Harter holds a Guinness record for counting from 1 to 1 million.
13. It took Jeremy Harter 88 days to count from 1 to 1 million, counting 16 hours a day.
14. If a person counted from 1 to 1 billion non-stop, it would take about 31 years.
15. A physicist created an equation to calculate the price of the planet Earth, taking into account its size, age, temperature, mass, and other factors.
16. According to the equation, the Earth would be worth between $4 and 6 quadrillion dollars.
17. Venus would be worth a penny due to its conditions being almost null for life.
18. When a file is permanently deleted from a computer, the operating system simply stops indexing it, making it invisible.
19. The file still exists on the hard drive, but the space it occupied is marked as blank and can be overwritten by other files.
20. The human eye is estimated to have a resolution of 576 megapixels, making it more complex than any current camera.
