As the title says. I’m actually thinking about this hard with my friends because everything that’s produced on Earth stays on Earth so it doesn’t change size, but what if it’s not from Earth but it stays on Earth?

    One of the proposed methods for terraforming Mars is to lob a bunch of icy rocks at it. That would increase its mass but more significantly also the energy of the falling rocks would convert to heat and melt the ice into water. So enough energy to increase Earth’s size would also heat the surface and kill life.
