There are a lot of scientific facts that we assume to be true in our day-to-day life but some of them aren’t true. I listed 25 of them below.
1. Overdrinking is not the only way alcohol kills brain cells
Overdrinking is not the only way alcohol kills brain cells, It can also kill them from a deficiency of thiamine for those getting most of their calories from alcohol and for very heavy drinkers from excitotoxin E which is nerve cells being killed by overabundant neurotransmitter presence when dropping alcohol cold-turkey everything is indeed best in moderation even when it comes to detox.
2. Lightning can and does strike the same place twice
Lightning can and does strike the same place twice since lightning aims to find the fastest path to ground tall buildings trees and such are at the greatest risk because the higher the object the more likely it is to be struck.
3. The tongue doesn’t have specific receptor areas for bitter sour
The tongue doesn’t have specific receptor areas for bitter sour salty and sweet flavors there’s a fifth taste umami for savory and meaty flavors and all zones of the tongue can sense all flavors.
4. A penny dropped from the Empire State building’s height won’t kill you
A penny dropped from the Empire State building’s height won’t kill you on street level terminal velocity the maximum speed an object can reach in freefall for a penny is and its fastest 50 miles per hour or 80 kilometers per hour not enough to give you more than a bump or just a little bit.
5. The human body or any organism won’t comically explode if you put it into a vacuum
The human body or any organism won’t comically explode if you are put into a vacuum rather the lack of oxygen would cause you to lose consciousness and die after just a few minutes.
6. The deoxygenated blood is not truly blue
The deoxygenated blood returning to the heart through the veins is not truly blue it’s a darker red school diagram show veins and blue for clarity but the blue color for veins comes from light hitting our skin and scattering into the wavelength on the color spectrum we notice as blue
7. The swelling of your fingers in the pool isn’t from absorbing water
The swelling of your fingers in the pool or after long showers isn’t from absorbing water rather it’s from your body narrowing blood vessels by contracting their muscle walls causing them to look wrinkled it’s believed this may have given our ancestors better grip in wet areas though it’s been shown we can’t handle things any better with wrinkled digits
8. Sunflowers don’t follow the Sun across the sky
sunflowers don’t follow the Sun across the sky but instead, they point East all day before the famous flower heads appear the baby buds follow the Sun to set the soon-to-be flowers in the right direction plants can be smart.
9. Gum takes seven years to digest not true
Maybe you remember hearing on the Magic School Bus that gum takes seven years to digest not true gum being in de Geste Balazs’s insoluble fiber passes through your digestive system at the same rate as whatever else you ate that day.
10. Your home goldfish has a better memory than you think
Your home goldfish has a better memory than you think goldfish’s memory doesn’t just last a few seconds rather it’s upwards of a few months.
11. Bats aren’t blind
Bats aren’t blind most smaller bat species do primarily use echolocation to find their way around but all bats have working eyes larger bats even rely on their night vision as opposed to echolocation.
12. Bulls don’t charge a Matadors cape
Bulls don’t charge a Matador’s cape because it’s red they see red as another shade of grey and no I don’t mean the book the Matador taunting and flag-waving are what causes the Bulls to charge.
13. Not all dinosaurs died during the asteroid impact
Not all dinosaurs died during the asteroid impact marking the end of the Cretaceous period modern-day birds trace their ancestry to smaller theropod dinosaurs that survived the impact though how is still a mystery.
14. Who lives in the far north boos won’t make you feel warmer now
In the sad bloat of everyone who lives in the far north boos won’t make you feel warmer now – tingly that’s another story drinking alcohol dilates blood vessels bringing a higher quantity of warm blood to near-surface skin and your body temperature lowers due to heat transfer between shallow vessels and the cold air.
15. Earth’s seasons aren’t due to our proximity
Earth’s seasons aren’t due to our proximity to the Sun. It’s actually due to Earth’s 23-point-four-degree tilt.
16. The eight glasses a-day thing is an overly generalized rule
The eight glasses a-day thing is an overly generalized rule much like the 2,000-calorie diet how much water you need depends on the temperature of your environment your activity level your size and other variables.
17. Water doesn’t flow down the toilet in different directions
Water doesn’t flow down the toilet in different directions in the northern and southern hemispheres the Coriolis effect the curvature of winds currents and other bits moving across the Earth’s surface do the rotation on its axis is most often cited for the supposed reverse flow but systems have to be massive for the Earth’s rotation have any effect the best example is our hurricane or a typhoon.
18. Life expectancy was much lower in the Middle Ages
Life expectancy was much lower in the Middle Ages it was nowhere near as low as 30 life expectancy is more of an average so the high rate of infant mortality at the time pulled the numbers way down some modern methods don’t even factor a person into the average until they’ve reached the age of 12.
19. Drinking orange juice or downing a bunch of vitamin C doesn’t keep you from getting a cold
Drinking orange juice or downing a bunch of vitamin C doesn’t keep you from getting a cold but it can shorten the duration once you have one.
20. No more waiting to take a dip after eating
No more waiting to take a dip after eating those swimming at a high intensity think Michael Phelps may lead to cramps for those of us not training on an Olympic level that old tale of increased blood flow to the stomach for digestion doesn’t cause us to cramp up in the pool now drinking alcohol and swimming that’s a different story.
21. People only use 10% of their brains right or wrong
People only use 10% of their brains right or wrong only a small amount of neurons are firing at any one moment the rest are still playing a role somewhere.
22. Earthworms don’t grow into two worms
Earthworms don’t grow into two worms when cut in half only the front part with the mouth will continue feeding and live o.
23. Scientists today have determined that we have up to twenty senses including thermoceptionn
Not to say we’re all instant superheroes but scientists today have determined that we have up to twenty senses including thermoceptionn for temperature and equilibria caption for balance – putting metal in a microwave won’t fry its electronics now don’t get me wrong it’s still dangerous as metal objects can become hot enough to cause damage to your skin or the microwave but it won’t send it to the graveyard.
25. The Great Wall of China cannot be seen even from a low Earth orbit
The Great Wall of China cannot be seen even from a low Earth orbit like where the International Space Station lies it’s barely visible and even then you would need phenomenal eyesight and clear weather conditions.
