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?

    I mean yeah. If you add stuff to a ball of stuff it get’s bigger.

    Currently Earth is actually losing mass at around 55.000 tons per year. (100.000 tons loss due to air escaping to space but gaing around 45.000 tons in dust and meteorties falling on it).

        > energy equals mass

        That doesn’t mean energy has a weight.

        It means it is physically possible to transition energy to mass and vice versa. Sunlight hitting the earth does not add any weight.

        Edit: turns out that part was wrong

        Also, earth radiates heat out to space. At a rate of (aaaaaaaaalmost, because of the greenhouse effect) 100% of the energy we get from the sun. If it didn’t, earth would be a few million degrees hot by now…
