30 Scary And Unsettling Things People Wish Were Lies But Are Actually Scientific Facts

The distance between the deepest part of the ocean and the top of Mount Everest is only about 12 miles (~20 Km).

It seems like most things in here about space but really the depth and amount unknown about the ocean is insane. The Mariana Trench is 6 miles deep.

I always thought it was cool that, throughout all human history, there are still parts of the world where no one has stepped foot.
Take a hiking trail for instance. If I walk even thirty feet off the trail, I could potentially be standing somewhere no one else has stood before. I could have been the first person to walk in that area.

I don’t have any evidence that this is the case but idk I had the thought one day so I figured I’d put that out there lol.

That objects don’t actually have color. Our eyes just assign a color to the wavelength of light an object reflects.

There's no reason in physics why time has to flow forwards. It's just how our brains observe it.

The surface of Mercury can reach lows of -290F -180C despite being so close to the sun.

I know I'm late to this but what really freaks me out about space is that so much of what we see is from millions of years ago. If we can only see what that star looked like millions of years ago, what does it actually look like today?

Spherically, the earth is about as smooth as a billiard ball. Even with Everest and the deepest parts of the oceans, they barely even register on the grand scene.

In our galaxy, a star goes supernova roughly once every 50 years. That seems to be the universal average rate of galaxies having stars going supernova. There are so many galaxies in the known universe that there are roughly 50 stars turning into supernovas every second.

Eventually (due to the expansion of the universe) nothing will be visible outside our galaxy

This will take a *very* long time tho.
