The Rest Mass Value of the Earth and the Moon

Authors: Espen Gaarder Haug
Comments: 2 Pages.

Here we will look at the value of the entire Earth if it is viewed simply as a form of rest-mass energy that theoretically could be extracted. However, as it would not be sensible to use our own planet (our only home at this time) as a form of energy, a better alternative would be to sell the Moon to aliens. So, we will calculate what the value of the Earth, the Moon, and other planets might be from an energy perspective. Of course, if advanced aliens ever do visit us, they might just look at the Earth as a clump of fuel; if they were sympathetic to human beings, they could pay us for it and let us keep the Moon, or even better, they could let us keep the Earth and they would pay for the Moon instead. On the surface, this is just an entertaining thought experiment, but there are deeper implications on valuation, energy forms, and negotiations within this story.

Moreover, it can become the locomotive of the entire economy of the state. What determines such opportunities for the village? How to reveal this? How does the economic fate of not only the village, but also the state, and even the world economy depend on this? The article attempts to answer these and other questions.
