Life is full of mystery, and many of them are still greatly unsolved. Despite being able to send a man to the moon, or give us iPhones loaded with amazing apps – science still can’t figure out such mysteries as; why we procreate, or, why cows must always face north or south when eating. So if you’ve been scratching your head about something in life you don’t understand, don’t worry, science probably doesn’t have an answer to it – or these either…
Why We Need Sleep
Given how much time in our lives we dedicate to sleep, there’s no doubt that we need it. In fact, every animal sleeps to some varying degree. But to this day, the best explanation science has for all this snoozing is “brain maintenance”. That’s it.
Animals Still In The Ocean
The theory of evolution is still the most consistent and scientifically founded theory we have. And as evolution has it, we all came from the sea – starting out as some kind of fish. But then one has to wonder if this is true: why are there still animals in the sea? Still to this day, all theories around why just don’t hold water (no pun intended).
Did you know that no matter how many times you cut a magnet in half, it will always have a north and south pole? Yes this odd fact is true, and still, very much greatly misunderstood.
Cows Facing North / South
No one probably paid too much attention to the eating direction of cows before, not even farmers. But one day a team of researchers looked at a bunch of images of cows grazing, courtesy of Google Earth, and noticed that they’re always facing one of the poles. And until now, no one can figure out why.
A Cat’s Purr
Any cat owner can tell you that his or her cat is content when it’s purring. But why do they purr? Science knows that they make this vibrating sound using their larynx – but as to why they do it – science still hasn’t a clue. Hey, nobody’s purrrfect.
So you participate in a study where half of the group is given a drug with actual medicinal ingredients, and the other, a simple sugar pill. And wouldn’t you know, both achieve results. But how? This is what’s called the “placebo effect” and science still can’t figure out how your brain is able to manufacture healing powers on a variety of ailments. What science is sure of is that the power of the human mind is far greater than anyone understands.
Why do we yawn? Well the best answer we’ve got so far is that it’s not because of fatigue or boredom – but due to a lack of oxygen flow. But even still, that’s just a theory and not a proven fact. And don’t hold your breath waiting for science to figure this one out either.
Costa Rica’s Stone Balls
While not as impressive as Stonehenge, Costa Rica is full of these stone balls everywhere that range in size from bowling ball, to eight-foot boulders. And wouldn’t you know it – know one knows why or even how they got there.
If you look up on a clear night’s sky, you may be lucky enough to catch colorful beams of light – also known as cosmic rays. They’re truly an awe-inspiring sight – and even more so when to this day, science still isn’t sure where they come from.
There are mummies found in ancient Egypt whose skin, hair, and bones are infused with cocaine. What’s so unusual about this is that cocaine originated in the Americas, and these mummies pre-date any recorded use of the drug. And no, no one knows how this is even possible.
Back in 2007 the NOAA (National Oceanic and Atmospheric Admin) came upon an extremely powerful and lengthy sound coming from deep in the ocean. It was a sound louder than any animal known to man is capable of making, and was forever referred to as “The Bloop”. So now science thinks there may be an animal larger than the blue whale, and likely, fiercer than the great white shark floating around out there.
Life On Mars
Mars is the one planet in our solar system that intrigues scientists the most, as it’s the only one that could likely have any life on it. While they’ve yet to find any water on there – which is a sure sign of life – they have noticed these dark and expansive streaks that show up near the surface during the planet’s warm season. And they have no idea or what they are.
