    I was kind of going along with this until you acted like the Earth became the size of the sun but somehow the water wouldn't also increase along with it and somehow the Earth would be shallower as far as the water? That doesn't even make any sense if the Earth was expanded to be the size of the sun I would assume the volume of water and all the other minerals and everything else likewise would be expanded at the same exact ratio otherwise there's no point in the comparison at all.

    Hi What If! This video is a total mind-blowing intellectual journey! ๐ŸŒŒโœจ Iโ€™m absolutely fascinated by your simulation of the 'Sun-sized Earth' scenario. The breakdown of gravity increasing 28-fold and the prospect of humans weighing a staggering 1,400kg was both mind-boggling and bone-chilling. ๐Ÿคฏ๐Ÿ’ช
    The segment on how oceans would become shallower and more prone to evaporation shows the team's incredibly thorough scientific research. Beyond the stunning 3D visuals, your take on the collapse of ecosystems and infrastructure provides such a deep insight into the delicate balance of our universe. ๐ŸŒ๐Ÿ›ก Thank you, What If, for always delivering high-quality content that piques the curiosity of millions. Wishing the channel even more success and more daring hypotheses in the future! ๐Ÿš€๐Ÿ’ฏ๐Ÿ‘‘

    Coincidently I just calculated this: If the Earth were 1 mile in diameter, it would have about one square mile of land and 2.2 square miles of ocean. About 1/3 of a square mile would be deserts, 0.22 square miles would be mountains, and 0.40 square miles would be forests, grasslands, lakes, etc. The Amazon would be 21 acres and Lake Superior would be 1/3 of an acre and about 2 inches at its deepest point. Mount Everest would be 3.6 feet tall, and the Marianas Trench would be 4.5 feet deep. And the Earth would have a population of 125 people.

    The title is wrong. It should be: "What if Earth sudently inflate to the size of the sun?". So thumb down because I counted of breakdown about how life may evolve if on the planet of that size.

    Wow, what an incredible livestream! I am absolutely blown away by the quality of this content. The way you presented the information was not only professional but also incredibly engaging and easy to follow. Itโ€™s clear that a lot of effort and heart went into this production. ๐ŸŒŸ

    The insights shared here are truly valuable, and I found myself nodding along throughout the entire video. Thank you so much for taking the time to share your expertise with the community. This is exactly the kind of high-quality content that keeps me coming back for more! ๐Ÿš€

    I particularly loved the interactive vibe and the clear explanations. Please keep up the amazing work; you are doing a fantastic job! Looking forward to the next one. Much love and respect to the whole team! ๐Ÿ”ฅโœจ๐Ÿ™Œ๐Ÿ’ฏ

    You gotta pick a lane here. Either the Earth is as massive as the sun meaning everything gets crushed into atoms immediately but wouldn't lose any land to water ratio, or you maintain the same amount of mass and the Earth pops like a rock balloon because the mass is stretched too far

    I think the logic is flawed here. You're not making the earth as massive as the sun – you're just inflating it like a balloon. Making it bigger means more soil and water. Then the gravity would crush us!
