A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

If we took material like rock from space and got it back to Earth enough times, would Earth grow as a planet? (sh.itjust.works)

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?

Energy don't have weight but, it does have an effect on the curvature of space the same way matter does. In fact one of the proposed methods to create artificial blackholes is to put enough photons into the same place. It's easier than getting matter together as photons don't interact with eachother.

However the point is correct that light energy will only impart an insignificant amount to the earth's pull.
