Mind-blowing science fact that may look surprising to you at first glance. But be happy as you learn them.
Cheetahs cant roar. They can only meow, like domestic house cats.
In BBC Wildlife Magazine, Stephen Mills made it clear that only four big cats have the capacity to roar: lions, tigers, leopards, and jaguars. The reason is that all of the big cats belong to the Panthera genus, and they have a ligament in their voice box that can stretch to create a larger sound-producing passage which made a wider range of pitch possible.
While in small cat-like cheetahs, the fixed structure of their voice box limits the range of
sounds they possibly can produce. They can purr continuously, but they cannot roar.
Bananas are berries but strawberries are not. This may sound weird but it true.
As botanists say, true berries are just simple fruits that stems from a single flower that has a single ovary and typically has several seeds. Many of these include kiwis, pomegranates,
eggplants, and yes, bananas. But in the case of strawberries, they stem from a single flower with more than one ovary, and this makes them aggregate fruits, along with raspberries and blackberries.
Bananas are radioactive The reason is that they contain potassium, and since potassium
decays, this is what makes it slightly radioactive. Don’t get scared, You will need to eat
10,000,000 bananas all at once before you can die of radiation poisoning.
You can make balls fly
Spin a ball when you drop it, you will notice that it will fly through the air as it falls. This concept is called the Magnus effect, and this is what makes playing tennis and soccer easier.
Water can exist in three states at once. The concept is called the Triple Boil, and at triple boil temperature, water exists as a gas, a liquid, and a solid simultaneously. But this requires very specific and precise conditions to achieve it, so don’t even have in mind of trying it at home.
Only one type of mammal has wings and this mammal would be bats. The truth is, while flying squirrels can jump from trees and even glide, they cannot truly fly like bats.
Helium can also work against gravity, this is because of the fact that when helium is cooled to extreme temperatures, and this is just a few degrees away from total zero (-460˚F or -273˚C), it will turn into a superfluid, this means it can flow without friction. It can as well climb up and over the sides of a glass. Equally, it can leak through molecule-think cracks in a container. If it starts flowing like a fountain, it will never stop.
Solar flares are scarily powerful energy, this is because the energy they release is the
equivalent of 100-megaton atomic bombs that explode at once. We are happy that the Earth’s atmosphere is protecting us from their radiation.
About half of your body is bacteria. According to a 2014 study, it is estimated that the human body consists of 39 trillion bacteria and 30 trillion human cells. Decades ago, researchers thought we were more bacteria than human with a ratio of 10:1. While this new calculation is probably closer to the true numbers, it’s not a hard fact.
Men are more likely to be colorblind than women. This is because the
genes responsible for the most common type of colorblindness are always found on the X
chromosome, this is what the National Eye Institute explains. The fact is that even if women have the genes on one out of their two X chromosomes, a properly functioning gene on the other one will make up for that loss. But if men inherit the gene on their only X chromosome, they’ll become colorblind. So sad.
