11 Confounding Questions That Even Scientists Can’t Answer


It seems like nowadays science boffins have it all figured out – but really, there’s still more than a few things that still leave them scratching their heads.


Even with all the studying and experiments, we’re about to take a look at eleven mysteries that still have no real logical explanation to this day.

1. What animals did some creatures evolve from?

There are quite a few species whose ancestors are completely unknown to us. For example, whilst we know that amphibians evolved from fish, we have no idea when exactly that happened. After all, the first land animals to crawl from the primordial ooze already had limbs and heads that were very well developed.

What’s more, if the dinosaurs became extinct 65 million years ago, where did the species of mammals that followed come from? Well, scientists sure don’t know!

2. How does a cat purr?

One of the most familiar methods of communication a cat uses is a purr, but no one’s figured out how they do it. Scientists do tell us that a kitty will make the vibrations using their vocal chords, which causes the sound. The frequency of a purr reduces pain and speeds up healing, so that’s why cats will purr when they’re hurt, too.

Special bonus fact: when a cat purrs, you can’t hear their heartbeat! Weird.


3. What was in that gelatinous rain, anyway?

In August of 1994, the people of Oakville, Washington, witnessed a bizarre and unexplained phenomenon. Weird, jelly-like stuff began to fall from the sky. A day later, an abundance of people experienced an illness with flu-like symptoms. What?

When analysed by scientists, the jelly “stuff” was found to contain two different kinds of bacteria. One of those is a bacteria found in the human digestive system. However, no connection was found between this discovery and the outbreak.

4. Do cows have some kind of magnetic head-compass?

Scientists were able to study thousands of bovines whilst they were grazing using Google Earth. An unexpected pattern was revealed: 70% of the cows studied turned their heads either north or south whilst eating or drinking. It made no difference where and when the cows were observed – they all still did the same thing.
