the video say The pressure inside the planet pushes the Earth's surface. The Earth is exploding, but space-time is compressing in the opposite direction, which prevents the Earth from exploding.

I know that it is more accurate to consider that the Earth is accelerating upwards because it explains why bodies of different masses are accelerating at the same speed. Objects are not accelerating downwards, but the earth accelerating upwards
