Scientists! They think they're so smart, just because they can explain everything.

Well, even the smartest folks get stumped from time to time,

or at least come across a problem where the answer isn't set in stone.

From mysterious shipwrecks to eternal flames, these are some discoveries and phenomena from across the world that have left scientists scratching their heads.

You're listening. You're listening. You're listening. Be amazed. Generally speaking, the older something is, the less novel and surprising it is.

Don't believe me, try busting out the hamster dams at a party and see if you get any laughs.

With that in mind, there aren't many man-made things on this earth older than the Great Pyramid of Giza.

Don't get me wrong, it's great in all, but considering it's been around for close to 4,600 years,

it can't have many more secrets or surprises in store for us, can it?

A few years back, Egyptologists announced they had discovered what they called a deep void in the pyramid.

This void consists of an empty space around 100 feet long and up to 230 feet above ground.

Now, this is what most normal people might call a corridor, but hey, let egyptologists have their cool name.

The discovery is strange for two reasons.

Firstly, as mentioned earlier, this pyramid is old, and we thought we'd explored every nook and cranny by now.

Secondly, we don't know what the purpose of the deep void was.

Even more strangely, the deep void was blocked by a large granite stone, so it wasn't just a deep void.

It was a secret deep void.

We have no idea why it was kept a secret.

Don't worry, I'm not going to say the deep void has anything to do with aliens.

They were probably too busy building Mount Rushmore at the time.

At some point in your life, you've probably been blessed by the multicolored hues of gorgeous

rainbows hanging in the sky.
