6 Easy Questions (That Science Has A Hard Time Answering)

  • Published on Jul 2, 2017
  • Science can explain things like thermodynamics, and yet some of the most mundane concepts, like sleep, bikes, and ice, are as big a mystery to scientists as they are to the average toddler.

    Because gravity isn't a force at all. It's the effect of the curvature of spacetime caused by the mass of objects. That's also why all objects "fall" at the same rate irregardless of their weight (in a vaccuum that is). There are hypothesis that suggest that the reason for gravity's apparent weakness is that it is spread out over multiple dimensions. It's a fascinating subject. Should we ever get a truly full understanding of it (unified theory) we may just be able to manipulate it though of course that's my own personal opinion. It would truly be cool to do so similar in the way it is portrayed in the movie "Interstellar:

    Ok we know why we sleep. Basic explanation: crud builds up on our neurons and block synapses from properly communicating, but sleep helps break down the crud and optimize function. And ice is slippery because the water molecules compacted creates very little friction, so our shoes have no grip and slip. Dude this used to be unknown but now? Science is catching up.

    Friction with the road keeps a bike up. As you increase speed the inertia of the bike and its rider increase similarly. As the bike lays down on its side, because the pivot point (the contact surface with the road) is so low and the center of gravity is so high, a small turn of the front wheel is sufficient to cause the inertia of the rider to right the bike.

    Wait, we know how gravity works. That's what Einstein's Theory of Relativity is all about. No gravitons necessary either, Einstein describes gravity as not actually being a real force, but a distortion of spacetime.
    What we don't know is how to reconcile Relativity with Quantum Mechanics or how gravity works on quantum scales.

    There is a theory that the only reason we sleep, is because we're just avatars/adapters for our souls to experience physical reality. And for the soul it is neccessary to "keep up" with what other avatars will be experiencing in order to build up contrast, which leads to a "microevolution" of your human personality....

    Hahaha. I'm not a scientist and even I KNOW how bikes work because I ride them, it's quite simple, actually.
    The frame divides your weight evenly betwixt the wheels where the spokes share the riders weight evenly across the entire frame into the wheels of the bike. Which allows you to balance on a bike.
    But in order for a bike to move the person on it needs to know how to do three things. Turn, balance, and move their legs in a circular motion to make the bike move.
    And the chain and wheel? It's a simple lever-pulley system, of course.
    Large wheels that are linked by the cassette, chain, derailleur, and bottom bracket allow for faster movement and pedaling speed.
    I Daniel O'Brien is just afraid of riding a bike. Lol

    that last one is not entirely true. Einstein gave us the theory of relativity and his idea is that gravity is essentially the warping of the fabric of space and time due to matter and/or energy. sure, on a quantum level gravity breaks down and stops making sense, but that doesn't mean gravity itself doesn't make sense. Einsteins equations are very very accurate and String theory may give us the insight on how gravity works on a quantum level. Time will tell.

    First of all, we kno how a bike works. Roll a coin down the hall. When it loses velocity, it falls over. Basically, the object is thrusted forward so hard that it can't fall over. The same applies to objects in wind tunnels. They stand up because of the inward force on both sides. Same reason sailboats don't fall over when a gush of wind comes from the side. This is not applicable to all objects of course Use could make a bike "stand up" without motion if it had thicker wheels. Throw 2 corvette tires on a bike and it's not falling over, but it would take a lot more force to move forward though. The democrats know this.

  • Tommy McDowell

    I don’t understand the bicycle one. I thought it was fairly simple how they work. They stay up right because the rider balances themself on it and it moves when the pedals are turned because the pedals are connected to the back wheel with a chain. I don’t understand the confusion???

    1. Can't speak for the rest of my species but, I don't care how sleep works it's my favorite hobby. I love sleep to those who say you can sleep when you die-Great! Let's speed it up. I'm happy sleeping because awake you have to deal with other humans...some on bikes. I prefer not to. Or deal with those who point out they don't like to sleep...
    2. Our bodies die, yes. We are all just energy who become gravity aka 'ghosts' 👻 Feel I should get scientific funding for that remark alone. So, I can sleep more in my slippery ice castle...with a ton of red pandas running around slipping and sliding. Yea, to me we don't need all the answers sometimes it's fun just to be. And enjoy the mystery.

    1. You have too look at sleep from an evolutionary standpoint. It is a way to preserve energy during hard times (over night, over winter etc.)
    2. Ice is in fact not very slipery. It takes spetial enviromental conditions to form a slipery shdeed over the ice. This is why they make it slipery before a hockey game.
    3. Are you kiding? Ask any decent matematician or a clockmaker how a bicicle works and he/she will explain it to you. Thats just bad reaserch dude.
    4. I give you that one, even thou I win at solitair at least 50% of the time.
    5. It is impossible to tell how many animals there are becaouse there are this two proceses called speciation and extinction. We dont know how many animals get extinct every day, but we know its much more then get "created." So its not even a fix number you are looking for. Also: bacteria are not animals. But most undiscovered animals are nevertheless microscopic.
    6. Gravity is not an easy concept and does not belong under this title.
    Bad video. Do more reasearch. Have a nice day.

    Why is gravity so hard to explain?
    I can tell you one gravity is so hard to explain why gravity cannot be measured found in particles. Because gravity does not exist
    That's pretty funny that science cannot explain why things fall to the ground. What's funnier is the way that you think about it. You have been told your whole life to gravity is a force pulling all objects to the ground why couldn't it be as simple as the Optics doing the falling is more dense than the air that's around me the molecule structure is more tightly compacted therefore it makes it heavier so if it's in the air will the molecules are not as dense then you should fall through air.
    If you drop a brick and a sponge into a a swimming pool the brick was sink to the bottom and a sponge will stay on top. If gravity was this Force pulling all objects to the ground then the sponge would be put to the ground just like the brick. But that is not what we observe what we observe is the sponge sitting on top of the water why. Because the sponge is less dense than the water therefore it makes it buoyant.
    Buoyancy and density that explains gravity
    You explain early in the video how we look at things and perceive time. Try and look at gravity in a whole new way. Most of the time the easiest solution to a problem is the correct solution it doesn't have to be rocket science charger stand when Things fall to the ground gravity is too complicated at leaves one confused
