The Deepest Hole

325

Russia tried to dig a hole through the Earth’s crust in the 1970’s. They reached 40,318 feet deep before they stopped. It is still the deepest hole humans have ever dug.

I’m curious about everything. Even subjects that don’t interest me…My life has been a quest for knowledge and understanding, and I am nowhere near having achieved that. And it doesn’t bother me in the least. I will die without having come up with the answers to many things in life. ~ Alex Trebek
