Idk... do we know the mass of the earth??

Circumference of earth: 40075.017 km
Mass of earth: 5.97237×10^24 kg
Age of earth: ~4.5 billion years
How do we get the numbers?
just a food for thought.


This is a good solution, but first you need to know the values-
1) the density of different layers. ( which isn't impossible)
2) the volume of different layers. ( which I think next to impossible, cause you can't measure it exactly)



Considering the mechanism of evolution, I think the chances are much lower.


True, it's so sad. :)

Have you ever been NASA?

Alas, I haven’t ever been in the organization of NASA, I’m just a curious soul that reads as my interests take me. For a number of years I wouldn’t read any fiction as I felt it had nothing to teach me. In recent years I have changed my perception on fiction as I realized that fiction gives you glimpses of another’s perspectives and life experiences and unlock more of the mystery of the human psyche. So even now, I sometimes have to force myself to read fiction, although I must admit, I enjoy the connection with the writer’s mind and characters.
Non fictions make me sleepy...

True, that's why I said that nonfictions are not as engaging as fictions.
But if you need to know something, you can't avoid the nonfiction.
( Hey, That means you can read a nonfiction when you can't sleep at night)
Haha yeaa, especially history books
