Hello everyone whats gucci! hope youre having an awesome day wherever and whenever youre
watching this! Im your host Ayman Hasan and welcome back to another video here at most
amazing top 10. We dont know everything and if im honest i think it will take us lifetimes
to know everything and even then we wont achieve it. I feel like if we as a species figured
out everything then like thats it weve won at life. We’d be able to do anything. But
lets come back from that dream and talk about the Top 10 Questions Science Cant Answer.
Starting us off with number 10 is Reality. We as humans, they as scientists, no one knows
if reality is real and we cant prove its real either. And im not just saying that as a generalisation.
Have you ever woken up from an amazing dream or a really bad nightmare and youre kind of
just stuck somewhere in between a memory and a dream? That feeling itself emphasises that
there are limitations to ours senses. Our senses may not be telling us the full story
around us, the people and things around us could very well be illusions and we wouldnt
know. They could be constructs of our own internal mechanism or created by our subconscious.
Scientists have admitted they arent sure if we’ll ever understand the true nature of
reality. The deeper we think about it the stranger it becomes. We already keep discovering
new forces, particles, functions etc that drive our world so for all we know the world
could have thousands of dimensions that we’ll never know of or be able to experience. I
feel like thats such a mind explosion we have no way to prove reality is real. This could
not be real but we wouldnt know that.
Coming in at number 9 is Ice. Hear me out. Saying ice is slippery is just like saying
water is wet. Its like how we cant explain what the colour red looks like we just innately
know. Ice being slippery is just something we know. But science cant explain why ice
is slippery. We dont know why we cant ski on boulders made of ice but we can ski on
ice. The most common explanation given is that ice expands when it freezes and so when
we step on it we compact it back into slippery water. But thats been refuted because theres
just no way our bodies exert anywhere close to enough pressure to squeeze it into a liquid
again. Other scientists think its that the surface of ice stays liquid open air is putting
pressure on it. Others say ice isnt slippery at all. So i dont know what to tell you and
neither does science.
At number 8 we have Dreaming. Now if youre someone who has dreams all the time or someone
that has like once a year we can all agree we know the experience of dreaming. Sleep
experts and scientists know when we’re most likely to dream, during the REM part of our
sleep cycle. REM meaning rapid eye movement. And we can actually see someone when theyre
in REM sleep because their eyes zip from side to side and they may jerk. If you have a pet
youve probably definitely seen it happen to them its cute when theyre running away from
god knows what in their sleep. But anyway, the one thing scientists cant figure out is
why we dream. We know the when but we dont know the why. Perhaps its just your brain
releasing stress or reflecting. It could be like Freud said and be about what your subconscious
wants and thinks. It could be a biochemical way for our brain to sort and store short
and long term info. It could be any of these reasons or none at all. Either way dreams
can be fun. Except i hate when im sleeping next to someone and then im just like *jerk*
and i wake up hoping they didnt feel that and theyre just like are you okay? And im
like kill me now.
Filling our number 7 slot is Solitaire. Im pretty sure solitaires the first card game
i ever played because it was always on any PC back in the day or on your nokia phone.
Klondike solitaire in particular is what we’re talking about today. Scientists just havent
cracked it. Mathematicians have even openly admitted the fact we dont know anything about
klondike is one of the biggest ‘embarrassments of applied mathematics’. When they tried
to figure out the odds of winning they ran into trouble. They couldnt even wrap their
head around the number of possible winning hands. The mathematician concluded that 80-90%
of hands are winnable but have you ever won 8 out of 10 times when playing? Thats what
i thought. They cracked how to win Monopoly which is a much more complicated game but
solitaire is clearly beyond our powers of understanding.
Now at number 6 is Consciousness. That inner voice that you always seem to be talking to
you or narrating everything in life essentially. Your thoughts if you will. Yeah we have no
idea what that is or where it comes from. Our brain obviously controls our bodies and
its functions and helps us think through lifes hurdles. But the brain is not the mind. People
dont realise those two arent the same thing. We cant explain how electrical impulses in
your brain a physical substance, is able to create a non physical substance our consciousness.
If we stray away from science, some religions say consciousness was given to us from God
as a gift to guide us in this world. Scientists theorise that consciousness is a bunch of
biological processes that contribute to a more complicated thinking that results in
this self awareness that we have because of the consciousness. We’ve determined that
animals like dogs also have consciousness but not as developed as ours. Really i dont
know how weve determined that cus theres literally no way to prove that or figure it out but
you know us humans. We just have to flex and pretend we know more than we do.
Coming in at number 5 are Extinct Species. And this one may be a bit of an obvious one.
These days in the 21st century most people think of everything as discovered, not many
people are out there trying to discover new creatures or places. But if you asked a taxonomist
whos literal job is to go out, find and catalog animals, theyd tell you that we are nowhere
even close. We havent even scratched the surface. Despite doing this job for 250 plus years,
we still discover more than 15,000 new species a year. So they have no clue at all about
how many species live on earth currently let alone how many ever have in the history of
life. Currently we know of around 2 million species but scientists have estimated the
number of species on the earth right now is anywhere from 5 million to 100 million. Yknow
small range just a whopping 95 million difference. In the 19th century taxonomists said there
were only 400,000 species on earth and weve already found 5 times that number. And all
this is excluding the fact that 99% of living space is under ocean and weve only explored
10% of it.
At number 4 are Bicycles. Yeah you wouldve thought physicists wouldve figured that one
out by now but still nothing. The design of a standard bicycle has barely changed in 200
years and still no one knows how it works. Even the guy who invented it had no idea what
he was doing it was just trial and error. He knew nothing about weight distribution
or balance or anything like that. Modern bike design schools themselves admit that the best
bike designs come from experience and intuition not science. We dont know how theyre stable,
how we ride them or how they keep going. For years scientists said we were able to balance
because of the gyroscopic effect which is the force that stops a spinning top from falling
over. But that was debunked. Others thought maybe it was the caster effect which is to
do with the angle of the front wheel but that was also refuted. So in conclusion, ask a
scientists how quantum physics works and he can answer you fine. Ask a scientist how a
bike stays up and theyll be like :O.
Filling our number 3 slot is Gravity. I really didnt think gravity would be on list. I had
to learn so much about gravity during school i was like we’ve got that figured out. But
evidently i was wrong. So gravity is 1 of the 4 basic forces that hold our universe
together but good ol gravity is the only one that makes no sense. We cant comprehend how
its so weak yet so strong at the same time. No matter how far you travel space wise gravity
never fully disappears. On one hand its the force that holds our solar system in place.
And on the other hand its weaker than the force exerted when bringing two magnets to
each other. The other forces in the world are controlled by their particles but we havent
found gravity particles or anything of that sort. If you go into even deeper like down
to atomic and molecular level gravity stops working. We have more knowledge about whats
inside an atom than we do about why a ball comes back down after we throw it.
Now at number 2 is Music. I think i love music more than anything legitimately i probably
listen to it for more than half the time im awake everyday its a vibe. These days the
production and consumption of music is massive. Its a huge part of the economy and it surrounds
us every single day. Now i can listen to music on my phone all the time privately privately
wherever. But 100 years ago the only music you really heard were from church choirs,
singsongs at home or fiddlers in a pub. An average american teenager now spends ⅛ of
their life listening to music. And we have no idea why. Some people thought music evolved
because it bonded groups of people together or because it helps attract a mate. But we
dont actually understand music. We know it can release dopamine but why do humans find
pleasure in listening to different combinations of vibrations at different frequencies? How
and why did people develop the ability to even be able to create music? Whats its purpose
its not biological. If i had to imagine a world without music right now things could
be marginally worse but that also sounds like torture. Yet theres no biological need or
purpose or anything for music. It just is. And thats all we know.
And finally at number 1 is Aging. Now for the longest time scientists thought aging
happened because of molecular damage that accumulates in our bodies over time. And this
damage is unavoidable because it literally happens because of us breathing oxygen as
well as other processes that are necessary for life. So cant exactly not do them. But
because of that damaged cells end up stop working altogether or they adopt new functions
that can trigger cancer cells or degradation. And by the 20th century life expectancy in
the US shot up from 45 to 78 so clearly were surviving for longer but still aging at the
same rate. So we know the processes that cause aging but we just know it in enough molecular
detail in order for us to intervene and stop it. Almost all organisms age yet there are
such big differences in life expectancy. Take the naked mole rat. Its life expectancy is
around 30 years which is 10 times longer than a normal mouse. But what makes that even more
mind blowing is the fact that naked mole rats have higher signs of oxidative damage than
regular mice yet they still live longer. So that experiment made scientists think perhaps
oxidative damage doesnt cause aging at all. And so if that is the, we know nothing at
all.
And thats it for todays video guys! I actually really enjoyed doing this one because i thought
we had the answer to most of the things on this list today. Kind of like how you assume
98% of things have answers but they dont. I hope you learnt something new today and
if you didnt then damn i really need to get better at these. As always im your host Ayman
Hasan and ill see you in the next one. Byee.
