The Heaviside layer is a layer of ionised gas occurring between 90km and 150 km above the ground — one of several layers in the Earth's ionosphere. It reflects medium-frequency radio waves.
Predicted by Oliver Heaviside (and Arthur Kennelly), its existence was essentially demonstrated by Marconi's transmission of radio waves beyond the horizon.
But would this layer prevent communications between the Earth and other planets? John Campbell wrote a story about men trapped on Ganymede with no way to communicate their whereabouts.
The description may remind you of the stiletto beam from Earthlight (1955) by Arthur C. Clarke. Comment/Join this discussion ( 0 ) | RSS/XML | Blog This | Additional
