      wouldnt down depend on your perspective, aka the way gravity is going./ center of the universe on a universal scale? Btw didnt watch yet so if im wrong yeah ight m st00pid

      It changes depends on position. So it's nonsense topic to think.

      Hello, please i have tried using multiple ways to find the name of the music used around <a href="#" class="seekto" data-time="969">16:09</a>, if ANYONE could enlighten me it would be perfect. Still thank you Michael sir, since i started i simply couldnt stop watching your videos, there they go, one after the other :)

    9. manloeste

      if in your mind you swap the "s" in Einstein to "sh", you come closer to how his name is pronounced correctly. Like "yne shtyne".

      can we destroy gravity in earth?

    41. Marvin

      I didn't really got it but it's very interesting😂

    42. Dory Azar

      I love how he went from throwing a pencil to talking about space time 😂😂

    43. Allen Doge

      I guess this guy is the new albert Einstein

    44. Tim Lewis

      I've heard that in the space between galactic clusters, the equations of space time are such that gravity is negative and the space between them is expanding, so it's not an inverse square law with unlimited range as we first thought.

      does the moon have a gravitational effect on us even if the moon is in space?

      Gravedad y Atracción Que me dices si dos lápices exactamente contrarios sobre la superficie de la tierra se dejaran caer a la misma altura? Ambos serían atraidos a la Tierra, sin embargo, la Tierra no podría atraerse a ambos lápices al mismo tiempo, no?

      Netflix: are you still watching? Us: <a href="#" class="seekto" data-time="179">2:59</a>

    55. theRealDuMon

      Watched this around 4am, & around min 10, started rage-thinking, "C'MON, QUIT FLEXIN & GET TO IT ALREADY!!" I'm fairly positive everything he was putting in was "related, but not necessary" per the Vid Title, but he could've EASILY labeled it something else to avoid "blue-braining" viewers: - "What You Think You Know About Gravity Is Wrong" (if he wanted to stay 'click-baity') - "GO HOME GRAVITY, YOU'RE DRUNK" - "WATCH ME REPEATEDLY POP-UP INTO FRAME FOR NO FUCKING REASON" 😆😂🤣🤣💀 - I could go on, but Rule of 3 dictates I shan't I literally started nodding arnd min 23, then left the planet arnd min 25. SNAPPED AWAKE 4m later into another vid in my queue, rewatched where I started nodding at (which is how I know the aforementioned deets), & forced myself to stay awake long enough to fall asleep watching "She-Ra", as not to got to bed angry (couldn't do that w/ "The Last Airbender" cause NO WAY I'd fall asleep, it's just SO GOOD!) I hope that was a good analogous example of "things that are related, but not necessary" for story-telling. If you do that again, w/out giving me fair warning, good sir, we're gonna have beef. 100% USDA Grade A beef 🥩🐮🐄🤣 It was like watching a substitute Physics teacher be try-hard w ZERO CHILL, tryna prove he can play in the bigs. As if the students'll rally to tell the principal, "OMG, HE'S SO PHYSICS LITTY, CAN HE BE OUR TEACH FULL TIME, NO CAP!?!" That's him using google to find current slang to create a substantive fantasy for his wank-bank 🤣

    56. John Barlow

      Technically, pounds are a unit of force (weight) in the US system, like Newtons are in the S.I. system. The unit of mass in the US system is the 'slug'. en.wikipedia.org/wiki/Slug_(unit)

        @John Rodrigues It's not that dramatic. Clocks ticks slower closer to the ground.

        @ritemoelaw_books83 but if you're on your side , your right side of your brain ages quicker than the left side 😉
