When Earth's radius doubles, its mass increases by a factor of 8 (since mass is proportional to the cube of radius), causing surface gravity to double from 9.8 m/s² to 19.6 m/s², which would double a person's weight and likely collapse most buildings; additionally, the Moon would be pulled inward past the Roche limit and violently shattered into a ring of particles due to tidal forces.

Why a 2x Bigger Earth Would DESTROY The Moon 🌍 🌕 #shorts #universe #science #planet #spaceAdded:
What would happen if Earth was twice as big? Well, the Earth currently weighs about 5.9 into 10 to the power 24 kg and has a diameter of about 12,700 km. So, let us double the radius. This [music] will increase the total weight to over 24,000 km. And since mass is proportional to the cube of the radius, assuming the density remains the same, it will become [music] eight times the current mass. The Earth now violently drags the moon inwards and once it gets [music] pulled up past the Roche limit, it violently breaks apart the moon into trillions of pieces and particles forming a beautiful yet deadly and unstable ring [music] around the Earth.
And according to Newton's law of universal gravitation, the acceleration felt by gravity will double [music] essentially going from 9.8 m/s to 19.6 m/s. A person weighing 70 kg may now weigh 140 kg. That is if you're still around to check your own weight because it's highly probable that many buildings would have crumpled because the foundation can't support double the weight. So, have you ever wondered
