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? Image
Not sure what “grow” means here exactly. But yes, the earth’s mass will increase.

I mean yeah. If you add stuff to a ball of stuff it get’s bigger.
Currently Earth is actually losing mass around 55.000 tones of mass per year. (100.000 tons loss due to air escaping to space but we gaing around 45.000 tons in dust and meteorties falling on earth).

If “energy equals mass”, shouldn’t we be gaining mass from the sun too 🤔
rockerface@lemm.ee 6 months ago
We do. The sun’s energy is locked in plants via photosynthesis, which is then processed by herbivores and passed further down the food chain. That energy exists in form of chemical compounds which are then broken down to release it during digestion.
In terms of numbers tho, it’s probably a negligible fraction of the Earth’s mass

We do, an infinitely small amount. Remember you gotta divide by c².

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.
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…
