Welcome back everyone to Most Amazing Top 10 - my name is Danny Burke and today were
gonna be talking about the Top 10 Scary Science Facts That You Werent Taught In School.
Theres a reason these facts arent taught in school - theyre the same reason our video
editor is probably gonna have a hard time finding pictures for this video - theyre pretty
gruesome, shocking and all round scary facts that science has uncovered.
You seem like an intelligent person who clicks on cool science videos so Im sure youll be
interested to learn about our sponsor today which is Brilliant - no literally.
Brilliant is an amazing puzzle solving app that will train your brain to make sure you
stay sharp and smart.
The app provides you with fantastic math, physics and science problems that are not
only unique - they’re also incredibly fun and engaging in a way you’ve never seen
puzzles before.
For example, the logic programme helps train your brain in critical thinking - a trait
that is invaluable in education and life in general.
There are more traditional courses that touch on topics you may already know from school
such as Mechanics or Computer Science as well as emerging fields of study such as machine
learning.
My favourite is Everyday Physics because it shows you that learning isn’t separate from
our everyday lives, it’s all around us!
Very clever stuff - go and check it out using our custom link in the description box below!
Starting off at number 10 now with a Biology fact Im just gonna call Bears.
Did you know that Bears are one of the only predatory animals we know of that don't kill
you if they catch you - they just start eating.
Scientists arent even 100% sure why this happens - it doesnt seem to make sense, other animal
that are predators, even humans at the top of the food chain, will always kill their
prey before eating.
Not bears though.
There have even been horrific stories of people calling their loved ones to tell them theyre
being eaten alive by a bear and theres nothing they can do …
Next up at number 9 we have The War On Microbes.
Modern medicine has done wonders in the fight against microbial diseases such as polio,
mumps and smallpox, saving countless lives.
However, viruses are crafty little things and they use mutation to fight back against
us.
Scientists develop a vaccine, it kills most of them but the few that remain become resistant
to the vaccine.
The influenza virus is now almost always resistant to the previous years vaccine.
New diseases have begun to jump from animals to humans, swine flu from bigs, bird flu from
birds and ebola from apes.
Some hospitals are now becoming filled with super viruses that have become extremely resistant
due to the all the vaccines and antibiotics theyve been exposed to.
Moving on to number 8 we have Capgras Syndrome.
There are many medical conditions that they don't teach in schools so heres a random scary
one for you.
Capgras Syndrome occurs after brain damage severs the connection between the visual and
emotional parts of your brain.
Everything else can be find but this severing means that you lose the emotional connection
to anything you see.
You can see your own mother, your best friend or your partner and you will know who they
are but youll feel - nothing - no emotional connection.
People with Capgras Syndrome often feel like everyone in their life is an imposter - they
look like the person they love, but its just not them …
At number 7 now we have Prions.
Prions are infectious agents made of protein material.
They form when proteins in your brain misfold - they cause Prion diseases which cant be
treated and every single one is lethal and will eventually lead to death.
Whats even more scary is that we don't know why they form.
They seem to just happen to random people at any given time.
So not only are they treatable, they arent even preventable.
Its kinda scary that you can try and live a healthy life and something like this can
strike a person down at any given moment …
Next up at number 6 - Your Mind Is Not Your Own.
Memories are incredibly inaccurate and easy to manipulate, we misinterpret information
to support preconceptions and sometimes invent entire new memories where there were none.
It gets so bad that the police have special interview techniques to try to piece together
what actually happened in events because human memory is shockingly bad.
Many people are proven wrong on details that they swear they remember.
Kind of a scary thought really - what do you really know?
Heres a weird one at number 5 - Anything that tastes good is bad for you.
Human taste buds evolved during a time when things like fats, salt, sugar and carbohydrates
were hard to come by - thats why we crave them.
The problem is, we now live in an age where most of you guys watching can probably get
all of those things very easily - thats part of the reason why some countries struggle
with obesity so much.
Basically, the human body didnt evolve to expect things like hamburgers, fries, fudge
cake and coca cola.
That means we now live in a world where everything that tastes good is easy to come by and ends
up being bad for us.
Basically humans have created a world where pleasure is now pain.
Maybe Im just a pessimist.
Moving on to number 4 we have The Speed Of Light.
Our universe is expanding faster than the speed of light.
What this essentially means is that there are some galaxies and stars on the other side
of the universe that will end up moving faster away from us than the light can actually leave
them.
The light from these galaxies will become redshifted until they become radio waves and
then nothing at all.
At that point, no telescope can help us see them.
If humans are still around by then, scientist may have to make do with just studying the
nearby galaxies in our local group.
Hopefully well have discovered faster than light travel by then.
Next up at number 3 - Were Living In A Simulation.
Heres a theory you may not have heard in school - well, I say theory, its more of a thought
experiment.
Follow me here - there are 3 scenarios for humans in the future a) we go extinct before
we develop advanced technology b) we live long enough to develop advanced technology
but cant create a true simulation of our entire universe or c) we actually do simulate our
entire universe.
If option C is true, then that simulated universe could develop life just like us.
If that happens, then whos to say it hasnt already happened?
What if we are that simulated life?
It sounds crazy but think of it in terms of odds - if this is true then whats more likely
- were part of the 1st and only true universe and we just havent got there yet, or were
one of perhaps countless simulated universes made by the real life forms in the real universe.
Gonna move on now before my head hurts too much.
Next up at number 2 we have Extinction.
Youve probably been taught about extinction at school - the most famous one is the Cretaceous
Tertiary event, thats the one that killed off the dinosaurs.
But did you know were actually living through an extinction event right now?
Scientists have said that human activity is responsible for the start of Earths 6th mass
extinction event known as the Holocene Extinction.
Ever since humans left Africa, their arrival on new continents has heralded massive losses
in specie diversity - especially in whats known as mega fauna thats large animals such
as the Mammoth.
The rate of extinction has only increased in modern times - its thought that up to 200
speciest of plant, insect, bird and mammal become extinct every single day.
Thats almost 1,000 times the normal background rate that scientists would expect to see.
Im gonna fish off now with another biology fact at number 1 - The Rat King.
This is just insane.
A Rat King is a phenomenon where a large group of rats become fused together by their tails.
The tails get entangled due to ice, dirt, hair, blood or even feces.
Rat Kings have been discovered throughout history - the record is 32.
Its a very rare occurrence - so rare in fact that biologists thought that the accounts
must have been false or fake.
However, real life examples have been found and studied in modern times and science can
confirm that this horrific, scary thing that sounds like its straight out of a horror movie
is in fact a real part of the natural world.
Alright, how do you feel?
Right here?
Grossed out?
Freaked out?
Just a little bit weirded out?
Then I think Ive done my job today.
Please do share any scary science facts you have in the comments section below - my name
is Danny Burke, thanks as always for watching guys and Ill see you all in the next video.
