What If Gravity Got 1% Stronger Every Second?

Earth’s gravity is increasing! It’s getting 1% more forceful every second.
After only 10 seconds, your head feels too heavy, and your arms and legs are sluggish. 100 seconds later, gravity is twice as strong as normal. It hurts to walk. Buildings start buckling under the increased strain.

Two minutes, and you’re getting lightheaded, you’ll blackout soon; your heart isn’t able to pump blood to your brain. Fifteen minutes later, everything is dead, and that’s just the beginning. How long until Earth becomes a star? Or, the biggest object in the Universe? And if Earth keeps growing, does the Universe eventually collapse?

    ​"What if Earth Became a Massive Super-Planet?"
    ​Imagine waking up tomorrow and realizing Earth has grown so huge that it dwarfs Jupiter! 🌍✨
    ​What would life look like on a planet of such unimaginable scale?
    ​Endless Journeys: Flying from one country to another wouldn't just take hours—it would take months in the air! International travel would feel like an epic space-age voyage just to reach the next border.
    ​Massive Wilderness: A single forest on this giant Earth could easily cover the size of our current whole world. Entire species, hidden civilisations, and unexplored vast ecosystems could exist without us ever knowing!
    ​A Whole New World Order: Instead of today's ~200 nations, we’d be living alongside 500, 600, or even thousands of huge countries! The cultural diversity and sheer size of maps would be mind-boggling.
    ​Cosmic Harmony: To keep life going, the Sun and the Moon would have to scale up, too. Imagine looking up at a massive, glowing Sun that lights up horizon after horizon, and a colossal Moon casting legendary night shadows!
    ​Time & Days: Day and night cycles would completely change. Depending on rotation, a single day could last for weeks, making a standard "24-hour routine" a thing of the past!
    ​How would humans adapt to living on such a mammoth scale? Would we build super-speed transport networks, or would each region become its own secluded world?
    ​One thing is for sure: exploration would never end! What’s the first country or forest you'd explore on a giant Earth? 🚀🌌

    I think you're taking quite a bit of liberty here – one big miss is that you're confusing the unobservable universe with the observable universe. Why would you think that the unobservable universe is growing at all; we've only been able to see the tiniest fraction of the entire universe. Also, I thought the premise of the video was that gravity increased 1%/s not that volume increased by 1%… and the strong nuclear force would break down between the matter and black hole stages in your timeline I believe; creating some of the more exotic starts that would have been fun hearing about.

    It's also impressive how you have 9 million subs but can only get 100k views and 100 comments on your video. How much did you pay for the fake numbers?

    The rate at which the gravity increases is aided by the amount of things getting pulled into it, so gobbling up the Milky Way and so on will begin to become an exponential growth. Makes you worry about that super duper massive black hole out there for the future of the universe, however expanding. Someone should make an idle gravity game for this.

    If the 1% increase/second compounded, it would be even worse. After 100 seconds, we'd experience 2.7g (1.01^100). After one hour (3600 seconds), rather than 36g, Earth gravity would be 3.6 quadrillion g (3.6 x 10^15, 1.01^3600).

    If the gravity increases by 1% every second, after the first second, shouldn't it incease by 0.011? Then once it reaches 2G, incease by 0.02 every second? As the gravity increases, the increase increment increase too
