Science Still Hasn’t Solved These Mysteries…

The science community has granted us a wealth
of knowledge that can never be overstated. Things that used to mystify our ancestors
can now be understood and more appreciated. It’s shaped our view of the world, the universe,
the animal kingdom, human psychology — literally everything you know has been helped along
by science and the men and women who dedicate their lives to finding out the whos, whats,
whens, whys, and hows of stuff. We owe them a tremendous debt of gratitude. But with science having that intrinsic aspect
of being ever-evolving, it’s never foolproof or absolute. Built right into the scientific method are
allowances for screw-ups or just plain not knowing something. And you might be surprised that some very
basic parts of life here on our planet totally baffle some of our best and brightest smarties. Here are some examples of mysteries that science
has yet to crack. 10. Why do we sleep? Now here is one you think we’d have nailed
down by now. Almost every single person in the world sleeps
daily (unless you’re a Rolling Stones guitarist). And the answer probably seems obvious to most
of us: we sleep to rest our bodies after the day. We can hold off on food, water, even sex for
days on end, but when it’s sleepytime, nature takes over and our bodies ask for the check. Except it’s not as simple as just needing
rest. Science has educated guesses which include
all sorts of reasons for sleep, like making time for our brains to get things in order
after a long day, to reinforce memories, or to replenish fuel lost while awake. But then you throw in examples of plants and
other organisms that don’t have any brains at all like we do, yet still have “sleep”
patterns similar to ours, and people who have gene mutations which let them function without
much sleep at all, and we begin to see our very limited understanding of why we sleep. 9. How does gravity work? Gravity, as we learn in school, is very simple…
right? There are forces within our planet that pull
things toward the center. So if you throw something in the air, it comes
back down. Gravity keeps you on the ground. It’s also what keeps the planets orbiting
around the sun. This is all very simple, and we’ve known
it since we were able to learn information. So why does science have so much difficulty
explaining it? Basically, gravity is one of four forces in
our universe, which also include electromagnetism, strong nuclear, and weak nuclear. Gravity is the weakest of the four, and while
we seem to grasp the concept of gravity with earthly examples, when things get too small
or too big, like black holes and atoms, that’s when science and Newton’s principles don’t
really make sense. And a simple science experiment you’ve seen
before, where a balloon rubbed on your shirt creates enough electromagnetism to negate
gravity and lift your hair or a piece of paper, shows just how easily gravity can sometimes,
well, disappear. 8. Why are most people right handed? People seem to take notice when someone uses
their left hand for something, as if it’s some kind of freak mutation that’s just
manifested itself. And while it’s rare for someone to be a
natural southpaw (about 10 percent of the world’s population), it’s not quite the
same as running across someone who, say, has horns growing out of their head. So why do people deviate from the norm, in
terms of handedness? Is it a genetic mutation? The environment they’re brought up in? Is it hereditary? Science doesn’t really know, and it doesn’t
even really have an empirically-established way to measure handedness. Science does lean toward genetics, but there
are even problems with that, as some teachers in school force children to become right handed
when learning to write, and there is some data as to cultural and societal factors influencing
which hand becomes dominant. Weirdly enough, we’ve learned why people
become right-handed, but not why right is the “right” way. If that makes sense. 7. Why does anesthesia work? It’s the divine gas that makes people not
have to be acutely aware of their leg being amputated, among other things. The introduction of anesthesia granted patients
the ability to snooze through all sorts of medical procedures, and it’s been a godsend
since the mid-1800s — not only for the patients, but for doctors who had to deal with squirrely,
wide-awake amputee victims. What started as an inhaled ether on its inception
has become a more refined chemical blend that renders the recipient unconscious. But we don’t really know how it does that. Think about it. When you’re asleep, you’re unconscious,
right? But you would sure feel a scalpel opening
you up, wouldn’t you? So why is the anesthesia unconsciousness different? And it’s an even bigger mystery as to how
the diverse chemicals in the anesthetic, ranging from steroids to inert gases, can work together
to achieve such a deep unconscious level that takes you about as close to death’s door
as is possible. It seems that under anesthesia, different
parts of the brain are affected much like a coma patient’s brain would be. All in all, it’s a wonderful tool in medicine
and we don’t really know why. 6. Why do cats purr? “Awwww, it’s because he/she LOVES ME!,”
you likely think to yourself, ignoring the fact that if that cat was a little bigger,
it would probably try to rip your face off. But it’s not a stupid assumption — most
people probably associate the low rumbly purr of the kitty-cat to a feeling of happiness
or contentedness. Science as a whole shrugs and meekly mumbles,
“I dunno.” See, cats also have a tendency to purr when
they’re scared or hungry. Purring probably isn’t a form of communication,
as it’s too low and local to be really effective. Also, in the realm of just pure weirdness,
science has discovered that purring has been linked to bone regeneration. So there are many theories we have for why
kittens just sit there and gently hum their bodies, but most likely it’s just a way
for them to soothe themselves. Kind of like how we laugh for several different
reasons. 5. Why was there a mysterious hum in New Mexico? New Mexico has had a weird history of everything
from nuclear bomb testings to Walter White standing on a dirt road in his tighty-whities. But the residents of the northern town of
Taos have their own strange tale to tell, and it’s in reference to a local phenomenon
called the “Taos Hum.” Since the early ’90s, people in the town
have described some kind of tangible audio event. Some call it a whirring kind of noise, or
a buzz, or a humming in the air around Taos. A professor of engineering at the University
of New Mexico studied the sounds around Taos, and noticed that around 2 percent of the population
was susceptible to the strange hum. That doesn’t mean that they picked up any
unusual sounds while conducting their research. Quite the opposite. Their very sensitive audio recording equipment
and vibration sensors picked up nothing out of the ordinary. The fact that the townsfolk heard differing
kinds of sounds is also of less scientific value than if they had all heard one low,
persistent hum. And that’s why science is more keen to dismiss
the Taos Hum as being part of the onslaught of background noise humans live in these days,
mixed with subjective hearing experiences from the people themselves. The residents of Taos, however, stand firm
in their belief of a weirder explanation. It is New Mexico, after all. 4. The ancient Baghdad batteries Now, hear us out here. What if we told you that researchers working
in Iraq in the 1930s found what totally appeared to be some kind of crude battery that may
have been used to produce electrical charges, and that it likely dated from around 200 BC? Of course, that would predate that kind of
technology by a couple thousand years. What archaeologists originally thought were
some kind of clay storage pots turned out upon closer inspection to contain copper rods
within them. This led the scientists to strongly believe
the pots would have held some kind of substance that would react to the copper rods and produce
electricity. But why? Theories range from using the charge to shock
people as punishment (those were stricter days), to using that electricity to electroplate
things with gold. Another school of thought is that they found
a way to make electricity long before knowing what the heck it was good for, kind of like
the Chinese with gunpowder. Our turbulent history with Iraq doesn’t
help us figure much of anything out, either. 3. Why does the placebo effect work? You’ve all heard the basics of the placebo
effect: it’s a treatment that isn’t “real,” but the very act of a patient believing in
its effectiveness creates its own beneficial properties. If you expect a pill or drug to do something,
it’s likely to work in some way. It seems mean, but science uses placebos especially
when testing a new medication’s effectiveness. Which, maddeningly, is skewed because sometimes
these placebos work. But why? Beats us! The point of a placebo is you don’t know
you’re taking it. But that opens up a whole host of problems
because placebos can often work even when you know you’re taking one. That clearly goes against its entire purpose. In 2009, researchers testing treatments for
irritable bowel syndrome found many subjects who knowingly took placebos got better at
higher rates than those who received no treatment at all. That’s absolutely insane. And it seems that a person’s personality
is tied to whether the placebo effect will work or not. But that’s just a guess so far. If that’s not enough stuff that science
doesn’t get, there’s also potentially an inverse nocebo effect, where if you don’t
believe a treatment will work, your symptoms will get worse. Our brains are weird, man. 2. Why are we getting repeating radio bursts
from space? Cue the History Channel “alien guy,” because
this is clearly some extraterrestrial stuff, right? Slow down there, Captain SETI. Let’s lay out the basics first. A fast repeating signal burst from space,
called FRB 121102, was first discovered in 2012. While we’ve come across some of these before,
this one has repeated itself, though sporadically. The bursts usually last about a millisecond,
and we don’t yet know where they originate from. We know it’s from a galaxy 3 billion light-years
away that was recently discovered, but that’s about all. The radio bursts, though short, are massive,
containing as much energy as the sun produces in a day. The fact that it’s persistent and repeating
makes scientists think the location could be near a black hole or a nebula. And the source itself has earned science’s
best guess of a pulsar or neutron star. But that doesn’t mean the fantastical minds
of scientists are ruling out extraterrestrial origins. What fun would it be to ruin those hopes? 1. How bicycles really work What?? If science is really going to tell us they
can’t figure out how a two-wheeled vehicle works, are we supposed to trust them about
anything? And yet, the humble bicycle contains so much
scientific mystery within. Much of the mystery concerns the bicycle without
a rider perched on it. If a bike is going fast enough, it’s going
to want to balance itself so it doesn’t fall over. It even does with when someone is riding it,
to a degree. That self-stability and why it occurs has
eluded scientists since the 19th century. The commonly-held idea that the gyroscopic
effect of the rotating front wheel keeps the bike stable has fallen apart under recent
analysis. An alternate theory likens the wheel on a
bicycle to the wheels on a shopping cart, in that they align themselves automatically
in the direction being traveled. That also fell apart. It seems science does have a point where they
just give up and break for lunch.

  1. Secret: the world's oceans are the largest solar cells that the earth has. Please keep this a secret so the US can continue supporting its 'phoney' fiat money for toxic oil. Our HEROS!

  2. "A point where they just decide to go and have lunch". Hahaha, I love your channel. I watch it every day and it makes me feel more knowledgable while having fun with it, keep it up!

  3. My husband is left handed, my son, who looks exactly like him ( they even have the same birth mark, in the same place) is also left handed. I definitely believe it's genetic.
    Love your work Simon!!

  4. There's a mutation that's very rare except for in a certain group (that group being people with autism) that causes a resistance to opioids. I have it. It affects how opioids ate broken down in the stomach, meaning that I'm still affected by injected opioids. I've had surgery a few times, and the anaesthesia knocks me right out. But after the surgery, when they give me some pills to take home, those don't do anything. I've been given codine and percocet. My sister and I both got our wisdom teeth removed at the same time, and she was all loopy afterwards and I'm just sitting there like "dude, chill"

  5. "We can hold off food, water, and even sex for days on end"

    Er.. Simon, I don't think SEX is on the same level of requirement as food and water… just ask any celibate lol

  6. The Taos hum is clearly some secret government experiment and/or the sound made by some secret piece of technology or installation in the desert. Of course scientists say they can't explain it, they're told to.

  7. Gravity isn’t real that’s why you can’t explain it. It’s just a theory. It has never been proven. Just more satanic lies.

  8. History Channel? The History Channel????? If it's on the History Channel, I believe it (not). After all, it's the HISTORY Channel.

  9. (just for a bit of fun); gravity doesn't exist, mass distorts space time, which it does not like so it pushes the two (or more) masses together to minimise the distortions.

    If you've had a general anesthetic you know what it's like to die.

    When riding a bicycle, as you begin to make a turn into a bend you actually steer in the opposite direction.

  10. I heard the "we can't understand how bicycles work" story before, and I totally thought it was a myth, honestly. I mean, how could we invent such a complex machine so early in recent world history and yet NOT know how it works?

  11. Yeah. Never fails, someone will notice I'm writing with my left hand and they'll ask "are you left handed?" I've gotten so cynical about that question that I'll usually respond with "umm, no?" Confuses the hell out of some people.

  12. When you turn a wheel it exposes more surface area of the tire to the road surface, which causes increased friction. When the wheel is straight it has the least amount of friction. Naturally, friction on either side of the wheel would keep it straight. It's the same reason why the tail of an arrow or airplane keeps to pointed straight.

  13. “We an hold out on feed, drink and even Sex for days out on end” lol

    Though, you might think this was a joke but guys actually will have complications if the “reserves” so to speak, don’t get cleared out every few months or so, if not it will lead to permanent damage and severe pain.

  14. isn't the reason why bicycles self-right the forward bend in the front wheel fork, which offsets the wheel axis from the steering axis, which together with the backward angling of the steering axis makes the weight of the bike and the rider push the front wheel upright a little bit? or maybe it's becauae of how the gyroscopic effect works with that bend and angling in the fork?

  15. Sleep involves processing the days memory and experiences into DNA memory which is longer term memory and deeper understanding into our sort of hardcore. Abstract processing of experiences and future concerns. Sleep is like resetting fast real time conscious brain ram for a new day, an attempt to wake up with a clear head or wake up with most relevant information for the new day loaded into fast memory after a night's processing of the previous day by our subconscious. I would say our subconscious is very active at night which is activated by different brain waves, sort of like having different brain modes, sleep mode is processing and deeper understanding mode and the consciousness is switched off to reset it for new day to load it with new experiences and then they are processed into longer term DNA memory based on importance at night, repeat experiences obviously increase the memory importance over time.

  16. On the bicycle.

    An object in motion will stay in motion unless acted upon by some external force.

    The rider keeps the forces in…..wait for it……..


  17. "No no no don't worry we aren't the history channel"

    Damn Simon (and by default the writers, I see you there at the keyboards) throwing some shade there. However, I'm inclined to believe. History channel has become a lot less about history and more about crack job theories and cheap gimmick shows. Hell, look at the Science Channel, they have more about history on there than the own channel that claims to be all about history.

  18. Concerning the Taos hum… This does not occur just there. Here in Washington, USA, we have the Vashon Island hum which is very similar.

  19. Please do a video on the difference between how and why questions of science.

    Please discuss proximate vs ultimate scientific questioning.

    “Why is the sky blue?” Is not answered with a how answer.

  20. I can explain the bicycle stability. How can I write to you pls? Great Video!
    Pls make a vid on the Plecebo and Nocebo effects. : )

  21. I don't know about a lot of the things on the video but gravity is connected to magnetism everything has a little bit of magnetism or small amount of energy within it therefore magnetism it can want to connect to its opposite that is why when we jump off a skyscraper we go faster and faster and faster to the ground polar opposite

  22. The mystery still not solved by any scientific method is how Simon makes all these videos every day and never sleeps… maybe he IS reptilian!

  23. Being married now some 42+ years to a left handed wife… My theory is that it is… well I don't really know either. But I do know they always want to sit at dinner to ones left!

  24. A cats purr actually heals bones. Our bones, it's frequency has been shown to stimulate bone growth and healing. Also they purr when happy, not hungry.

  25. For the bike, since a change in direction of a tire would change the direction of the handlebars, wouldn't the wheel slightly turning right increase the drag on the right handlebar (due to the right handlebar being further from the center of the circle being formed, thus must be going faster than the left handlebar, increasing resistance) causing the wheel to turn back to the right? The faster a bike goes would make this correction faster due to increased resistance. In short, it would be such high frequency oscillation that it would appear perfectly straight to us.

  26. Why are hotdog buns in packs of eight and hotdogs in packs of ten? And, if Keith Richards sleeps, he’ll die, so…

  27. why are most (minus 1) amino acids are and not a 1:1 ratio of R:S? what guided the early primordial prochiral precursor?

  28. Things that are right-handed that lefties have to deal with;

    Most tools
    Most guns
    Cooking utensils are kinda even..
    Computer Mice
    Videogame Controllers

    What'd I miss?

  29. I discussed gas was a dental assistant when I was getting a couple teeth pulled. We came to the conclusion gas doesn't take the pain away it just makes you not care about it

  30. I think we problem have to sleep so our bodies have the time to heal the damage that's occurred over the day and allow our immune systems to clean the place up. Every week your immune system kills a few cancerous cells.

  31. We sleep so that we don't suffer from a lack of long term memories… plants have a circadian rhythm… 2 very different things…

  32. And static electricity with hair isn't defying gravity… it's like a bond of the electrons. your hair becomes negatively charged and the balloon positively charged or something like that. it's the way lightning works. it's just a giant static discharge. it's like saying when a magnets picks up a nail that the nail is defying gravity.

  33. The placebo effect is fascinating. There are actually medications that can "block" the placebo effect. Also, people conditions like Alzheimer's and Autism seem to not be able to experience the placebo effect as well.

    And, no, science is not sure why.

  34. Actually, we've pretty much already cracked the code on the gravity thing back in 2015 with the discovery of the Higgs Boson, adding to the new periodic table which only has 13 elements; Electon, Muon, Tau, their three respective Neutrinos, as well as the Up, Down, Strange, Charm, Bottom and Top quarks; and now the Higgs Boson as well. The mass of the Boson itself was thought to be what generates the gravity field around anything via an excitation in the 'Higgs-field,' and was proven to be true by CERN with the L.H.C. a few years back as mentioned before. Basically, it's quantum field theory in a nutshell…

    'If that's true, then where's the anti-grav & flying cars?"

    First of all, this is still an EXTREMELY recent discovery and it's still going to be some time before we understand the concept fully because they're STILL reviewing the data from the perfect head on collision 4 years ago today, and will for some time! That being said, it was still very much only theoretical and we really didn't know how it worked up until only a few years ago, so technically, it does qualify for this list.

    Secondly; people can't even fly a 2 pound DRONE without crashing into something & you want to give them a 2 ton flying death machine??? BRILLIANT!!!!!!!

  35. baghdad battery for mind control or electroshock therapy to create slaves. trypanning provides suitable holes in the skull

  36. “Community Announcement: Daven is back to catching flies with his tongue. As such, Simon has returned from basking to host again. All hail the scaled.”

  37. Interesting about anesthesia in my case is in sleep you seem to be aware of time passing, where in surgery it's like you see the nurse and the doctor and the next moment you're being awakened, as if the hours long surgery took place in the blink of an eye.

  38. My friends grand father swore wearing a flattened copper tube as a bracelet helped his arthritis. Guess it’s an old wives tale. But he believed it.
    Granny tried to get a doctor to tell him it was dumb…instead the doc said if he thinks it’s working, and he feels better, go for it. It’s no harm to him.

  39. I don't remember anyone making me write right-handed, but I kick left-footed, and if I don't think about it, I deal cards and throw a Frisbee left-handed. I threw a baseball right-handed, probably because we only had a glove for the left hand when I was learning.

  40. According to general relativity gravity is a result of the curvature of space-time due to energy or matter and is not actually a "fundamental force" at all.

    Although the scientists that study gravity think it can be quantized, that wouldn't make it a fundamental force.

  41. I solved the "mystery" of fast radio bursts last time I got stoned! It was easy!
    OK, so we've got Fast Radio Bursts. F R B, right? Frb… What does that sound like? It sounds like a fart, right? So Fast radio bursts are the farts of cosmic beings! Easy…

  42. There is nothing mysterious about bicycle stability. The caster of the front wheel tends to straighten it. When the bike leans the front wheel turns in the direction of the lean because of the caster. This causes the bike to turn in the direction of the lean, which moves the wheels back toward being under the center of gravity. This is why it's possible to ride a bike without using the handlebars. You steer it by leaning. What many dont realize is that experienced riders unconsiously steer by leaning even if their hands are on the handlebars.

  43. Maybe the people studying the Taos Hum are going about it the wrong way; rather than attempt to detect the sound, what they should be doing is studying those who hear the hum to identify if they have differing mechanisms for perception as opposed to their neighbors. The hum may exist, yet at a perceptual level for which we have no mechanical means to capture it that can only be observed (or rather, heard) by those with a rare physical apparatus within them. It might even be (bold concept forthcoming) a sign of evolution – a small number of people with a perceptual capability that might wind up proving to be beneficial in a way we are not yet aware of. Sometimes science is stymied simply because it takes time for someone to think of the right approach to a problem to arrive at an answer… and sometimes science lucks out and discoveries are made entirely by accident, like Penicillin or the Microwave Oven. It seems obvious that the Hum exists, it is reported too often to be otherwise.

  44. The final part with the bicycle is greatly multiplied when applied to motorcycles. A motorcycle can literally have its rider fall off and have the back wheel catch traction again (while nobody is on it) and pick itself up off its side and continue down the road a distance.

  45. Putting your right hand in danger is is more adventurous then your left hand if you lose your right hand it is inconvenient if you lose your left hand because of the arteries in your left arm it could be life threatening

  46. "Does time exist?"
    "Why does the human body actually lose 21 grams after death?"
    "Is it possible for a leftist to not be an angry, miserable person?"

    These are some of the questions I want answered, definitively.

  47. For the placebo effect, there is a theory relating to psyonics basically stating that if people believe in something enough that it will happen.

    This could, alternatively, be proof that we are merely a simulation and this effect is merely a "cheat code" like effect of bypassing normal laws in order to attain a desired effect.

    In history, especially among occult practitioners, belief and will-power were thought to be where magic came from within humans, and why some people could do things that were thought to be impossible. Of course, it's equally likely that people were just really stupid and taken in by clever con men.

    Or, maybe humans are just really weird. That one works best for me.

  48. The bicycle acts like an arrow I was always to told in the way they fly stable ??? Would be interesting to hear more on that as you never mentioned it ??????

  49. #8… It's your RIGHT hand because it's the RIGHT one to WRITE with. It's your LEFT hand because when writing, it's the one that's LEFT. LOL

  50. i always lucid dream, does it mean im always conscious? i feel im always awake its just sometimes im here and sometimes im there, riddle me that

  51. I remember the history channel and website being great for history esp. American history. Then I became increasing interested in WWII and hitler. This lead to some in my history department calling it the Hitler channel or Nazis channel. I peaced out when aliens got involved. That's not history. It's not even facts.

  52. some dude from atlantis went to Baghdad and it looks like a clay pot to blend in so he wouldn't be found out and murdered… he used it to make toast.
