  • Satellites, Planets & Sun have there own gravity force. That's why Satellites revolving around Planet, Planets revolving around Sun etc. I think gravity force of Sun is more powerful than the gravity force of Planets, that's why it's holding Neptune & Pluto. Why Sun's gravity not able to hold the Moon? What force make Satellites, Planets & Sun sipn on axis?

  • Question: DNA sampling using a cheek swab. How does the test isolates the Human DNA from all the other DNA from bacteria that also live inside the mouth?

  • Take diode from your remote control connect battery (3V or less) to it. Then tape it to the camera that it "lights" to the sight of view. Turn on the camera and walk into dark room. Viola. Your night vision googles.

  • IR is a nice technology but it has nothing to do with night vision, you can totally use it in day light. Night vision is purely visible spectrum amplification, that can be either active or passive, depending on the system used.

  • How does marijuana work? Or hell, any other drug. Drugs tend to have pretty interesting effects on how the brain functions, I'd love to hear about one of them from you guys.

  • Question, since image enhancement amplifies scarce amount of light, you wouldn't be able to see anything through it when there is absolutely no light at all, right?

  • Don't curse and or express your emotions with the name of god. it's a sin and i don't want you to 
    go to hell. 
    Repent or perish, bless you.

    Damn=cursed by god to forever suffer in hell. Do you really want to say that?
    Instead of watching TV and playing video games. You should go read the bible. God is coming back to bring forth judgement. go to him and repent from your sins before it is too late.

    Lying is a sin.
    Adultery is a sin.
    Unrighteous anger is a sin.
    Magic=Satanic witchcraft=sin=death=hell=eternal punishment.
    Hatred is a sin.

    Practicing Masturbation and the use of Pornography is a sin. i am sorry but it's true. confess to Jesus(god) and repent.
    Masturbation and Pornography also have harmful and addictive effects as well. It destroys families, make people lose their jobs etc… Quit before the harmful effects get to you.
    Bless you, peace.

    Being a Homo sexual is a sin. i am sorry but god did say it in the bible. 
    i am just here to warn you,it is totally up to you to decide or not you want to confess and repent 
    your sins to god.

    Having sex before marriage is a sin(Anal sex is a sin as well). confess and repent before god so that you may have eternal life.
    bless you, peace.

    Lusting after the flesh is a sin. In the eyes of god, it is is adultery.. Repent or perish.

    I am not forcing you to do anything. All i am doing is preaching my believes. You have a choice of going down the path that you are currently on that leads to destruction, 
    OR follow god and walk his path to heaven.

    Hell is a place od destruection

  • I'm honestly sorry that you have so few subscribers/views. This is high quality content, considering multiple factors that make a video, not just the information. Keep up the good work!

  • A question please : why we never landed back on the moon ??!!!!!!!!!!
    it was a big lie right ? , I believe that so

  • It would be great if u add subtitle in your videos.. because u speak too fast… and.. im from malaysia which is english isn't our main language. BUT all your video is good though. Gud job there

  • Im defently subbing u guys your the best I hope yall get 1 million soon because im getting smarter coz of you dug hehe thx guys for these vids

  • forgot to mention why night vision is typically green. It's because the human eye can distinguish shades of green better than any other color. Thought that was interesting and wanted to share though many probably already know. great vid!

  • Hello everyone here's something interesting, which got me thinking

    If I were in a room that was extremely dark, no windows,

    And now I have night vision goggles,

    If I have a mirror, could I see my reflection?, is it even possible? Could the night vision goggles prove useless when it comes to mirrors in the dark?

    Interesting thing to think about hey lol

  • Uh, ir night vision? Not thermal? Ya know those cameras with ir bulbs in the front? How does that work?

  • Her face is bullshit if she was standing in front of me i will spit on her face my dog look smarter then her and you should cover your face next

  • predator use thermal vision 😅, not night vision
    thermal sights -for detection
    night vision- for identification(like the blinkers of us army vest that can be seen when using night vision)

  • Can anyone explain to me what the high pitch sound when turning on the goggles? I ask because I am trying to understand if the headset is using an electrical capacitor. If anyone has an answer please respond.

  • The video was a very rapid overflight of night vision devices. You didn't cover the essential role of photo multipliers in the amplification of the available light, as well as the use of IR illuminators to increase the non-visible light. Don't be afraid to get a little more technical. You can also make these videos multi-part for those viewers that want to go into more depth.

  • Not certain about the points made but ,if anyone else wants to uncover
    bad eyesight
    try Magonsi Simple Sight Expert (Have a quick look on google cant remember the place now ) ? Ive heard some decent things about it and my friend got great results with it.

  • You should definitely cover next.
