However, the traditional newspaper (if there really is such an animal) is threatened by shrinking readership. Television is focused on entertainment, even when it dresses it up as news.. Radio is threatened by satellites. All are confronted with the frictionless distribution enabled by the Internet, the disruptive effects of digital information. None have figured out a business model that pays for content at today's rates.
Thunder is a compression wave and will dissipate with time and distance. Under excellent conditions, thunder can be heard about 12 miles away from the lightning strike. However most of the time conditions arenât this good and we usually canât hear thunder any more than about 5 miles away.
Thunder occurs when energy from lightning heats and rapidly expands the air. The resulting sound wave gets heard as thunder. While lightning and thunder occur at roughly the same time, lightning travels at the speed of light, or at 186,000 miles a second, while thunder travels at the speed of sound, equivalent to one-fifth of a mile in one second. People see the lightning long before they hear the thunder.
