This question mixes the fantastical notion of a force field with some down to earth mathematics, and it’s the latter I need help with please!(adsbygoogle = window.adsbygoogle || []).push({});

Assuming the following:

• a truly huge force field capable of shielding a continent, i.e. along the coastline,

• it is visible as a coloured shimmer,

• it reaches roughly as high as the definition of the edge of space, say 100km,

• all of this on a planet the size of Earth (say exactly the same for the sake of calculations),

and taking into account the curvature of the planet, how far away would the force field be visible? I’m wondering about observers on neighbouring continents, or on ships, how close would they have to be to see it?
