    Dark energy 75% compressed is dark matter with zero space of magnetic 🧲 poles.

    Dark matter 25% is the black hole 🕳 or neutrino.

    Mass 5% some of the mass when loosed returns back to dark matter when it is compressed.

    Each planet and star has a trapped neutrino into their cores what gives them spin. The bigger the mass the bigger the magnetic 🧲 field the more the mass.

    Dude, thanx for the information. But please calm down!!! This stuff is already hard for most of us, let alone at the speed of light.

    When you turn the light on in the box with the mirrors the mass remains the same because even as the battery empties the light is still in the box thanks to the mirrors. However, once the battery dies, there is no more light and there is no more energy in the battery. So does the mass instantly drop ?

    What's your hurry, man?
    "Booyah", nothing. Everything he spewed before that word lacked potential. It was entirely kinetic.

    The Universe was created through the Big Bang at a Point of Singularity.The Energy was E=mc2.
    Where did that Energy E come from?The Laws of Thermodynamics state that Energy cannot be
    Destroyed,but it can be changed from one form to another form.
    I know was caused the Big Bang which created the Universe at the Point of Singularity.I also
    know what Existed before the Big Bang.I am an Engineer/Scientist.

    I manage to find the result. E=MC2 = 1,96954E21 ! If you get out the box in fact its very easy to calc. it 🙂 Wish all luck! See you soon. :))

    I've watched Matt's videos at 1.75x speed for a day, and then now watching this video at 1x speed made it easier for me to absorb

    I really regret not watching this video full,the first time I watched it,Bcz I didn't know abt quarks.I cd hav cm to know abt Veritasium much earlier and that matter-antimatter annihilation r also not converting mass to energy.

    Sry mate, you selected the wrong career, you should be working with Eminem.

    You know I'm kidding.Excellent video btw!

    No. The mass of earth will not increase I think.
    Because the chemical energy of my body ( or heat whatever) has just converted to potential energy of the hammar.
    So m(rest)+m(extra) is the same before and after.

    Nothing will happen
    As soon as you lift the hammer the gravitational point shifts to your feet
    Adding a little extra weight to it
    But its simple to light for the massive size of the earth, its just a too big spread survace
    Also think of the kilometres of crust the earth has not a dent could be made

    I get it the proton is positive plus positive is equal to positive and the neutron is negative plus negative is positive they are mass??

    I watched this in 2016,2017 and 2018.Didn't understand anything.I read relativity from my text book and now I understand this in 2019. So folks go study first!

    Lindbergh…..Does a fly, flying inside my airplane add to the weight.?
    Answer … It depends on if the windows are open.

    So I've heard so many other scientists say e=mc and this is what I've been told it is called but this guy goes off one paper where einstein wrote it differently and acts like that's the true name. Seems like he is being condescending by saying it like that, just use the goddamn term everyone knows 😂

    The whole thing about light not saying anything but still contribute to mass, is that how lasers can manipulate particles? Like laser eye surgery?

    Got it?" Ummm, no! What's frustrating is how these people think talking fast makes understanding such a complex theory easier.

    If they can measure the weight change of light than maybe someone should retry that 1800s test for when someone dies there soul leaves and it gets lighter 😂

    Earth's mass will not increase because the potential energy gained by raising the hammer is equal to the chemical energy lost by the muscles of people's arms.

    1. the guy talked at normal speed. Normal people think so slow that i make up funny songs using the first part of the sentence.
    2. Mass is momentum in the direction of future time. Light is momentum in space only, which is perpendicular to time.
    3. I didn't think up 2; Feynman did.

    So is the earth getting heavier due to the portion of photon mass that is reaching us from the 4000000000kg per sec that the sun is losing.?

    So if the sun is losing mass because it's releasing light, and since everything above 0K gives off photons in the form of black body radiation, does that mean I'm always losing weight by glowing in infrared?

    Let me give you a metaphor of how the mass of an electron can be less than the sum of all its parts: The speaker in this video thinks that he is intelligent to understand all this stuff, but he lacks the intelligence to realise that unless he slows his speech no one will understand what he is saying. Therefore he is less intelligent than he thinks he is.
