Fact Of The Post
If all colors are in the rainbow, then where's pink? According to scientists, pink isn't a real color... it's a human-made color.
Science is the ever-growing field in which with time there are so many things invented and made by scientists and creators that might you have never seen and known.
So, let's start with the new unknown scientific facts.
Science Facts
💪💪💪 Let's Start Reading These Facts 😤😤😤
Did you know that dragonflies are older than dinosaurs?
If you were to go back about 300 million years ago, you’d likely come face to face with the ancestors of dragonflies, meganisoptera (sometimes referred to as griffin flies).
This long-extinct relation of the dragonfly lived from 323 million to 250 million years BC during the Paleozoic era.
The vast majority of griffin flies were a similar size to their modern cousins. However, one species called the megatypus would most likely scare the living daylight out of you if you were to encounter it.
The clue is in the name, as the megatypus grew to an alarming size, with a wingspan up to 28 inches (70cm)!
Why don’t we hear thunder at the same time as seeing lightning?
The main reason for not hearing thunder at the same time as seeing lightning is that sound waves travel slower than light.
Light waves travel at a faster speed, so we will see the flash before we hear the rumble.
There is a myth that if you count the time between seeing the flash and hearing the rumble, you can tell how far away the storm is.
However, this has been proven not to be an accurate way of measuring the distance between yourself and the storm.
This technique can be used to estimate distance but with a little more math than just counting.
Did you know that sausages were invented as a way to preserve meat?
These days it’s easy. You can go to a supermarket, pick up a fresh pack of meat, bring it home, and whack it in the fridge.
If you don’t feel like using it straight away, you can pop it in the freezer and save it for another day, week, or even month, all without a thought!
Things weren’t always that simple, though.
One of the original ways of preserving meat was to salt it, which is to cure it in a large container of salt.
This method would preserve the meat, allowing it to last throughout a season if looked after properly.
At some point in time, the Sumerians, or possibly an earlier culture, figured out that if you stuffed all your excess meat into some intestines and then salted it, it could last even longer, making it even tastier!
What does the immune system do?
The immune system fights against invasive microbes or germs to ensure they don’t stay in our bodies.
This includes chemicals and toxins too.
The immune system keeps track of all the microbes it has ever fought.
This means that when an unwanted microbe enters the body, the immune system can recognize it and know how to attack it.
Not only does it recognize it, but it can also attack it quickly before it affects our body.
So, for example, when we catch a cough, our immune system learns how to fight it off, but this can take a week or two.
Then when our body is exposed to the same germs again, it can recognize them instantly and fight them off before they attack our body.
This means you will experience little to no symptoms of a cold you have had before as your body knows how to stop it.
What happens if a person goes into a black hole?
Ah, the burning question – hang on to your space helmets because it’s about to get bizarre!
Remember I told you black holes had an exceptionally strong gravitational pull?
Legendary scientist Albert Einstein determined that gravity, if strong enough, can warp space and time as we know it and cause it to curve.
Therefore, if an object is dense enough (think of all the mountains in the single water droplet!), it can literally curve in on itself and burrow a hole right into the fabric of space.
The deeper you go into the burrow, the more warped and mangled it gets until you reach the “singularity”.
This is the point where the curving of space and time becomes infinite; space and time as concepts become meaningless, and the laws of physics, which rely on space and time to be constant, no longer apply.
So, if someone were to go into a black hole, reality would sort of… split.
Science Trivia Questions And Answers 😲😲😵
Who invented science?
Aristotle is considered by many to be the first scientist, although the term postdates him by more than two millennia. In Greece in the fourth century BC, he pioneered the techniques of logic, observation, inquiry and demonstration.
Who is the first scientist's name?
But for his pioneering use of experiment, observation, and maths to understand nature, the Italian genius Galileo Galilei arguably best fits the description of 'first scientist'.
Who is the No 1 scientist in the world?
Albert Einstein is one of the most famous scientists in the world. He used to be an eccentric person who was perhaps the only scientist in the world who has become such a household name. His theories of relativity, gravitation and his understanding of molecules have defined new approaches in science.
Who is the best scientist alive in the world?
Arguably the world's most famous living scientist, Stephen Hawking is known for his landmark contributions to our understanding of the big bang, black holes, and relativity.
Who is the first female scientist?
1732: At the age of 20, Italian physicist Laura Bassi became the first female member of the Bologna Academy of Sciences. One month later, she publicly defended her academic theses and received a Ph.D.
