Whenever you hear someone illustrating/describing the transmission of radio waves they always make it seem like they'd travel perfectly around the Earth to another distant location. For example, a radio wave sent by alternating current to be received from an intercepting device on the other side of the planet. You'd think of something like:
Top frame shows how most media works, etc., would illustrate it: radio waves illustrated to go perfectly wrapped around Earth like a straight line until it gets to the other side.
Bottom frame shows how it should work (supposedly) if radio waves travel at all directions at the speed of light: will go right through the ground to the other side of the planet.
Basically, it will travel in all directions, but measuring how it gets there it should really appear like this, no?
To put the question in perspective, will radio waves go right through the ground and reach the other point near instantly, all on the other side of the Earth?
