Now that "our rains" have arrived, lets talk about Rainbows.
Long before modern science began to understand the processes that create our
weather, people made up their own explanations. Many of these accounts were
fantastic in nature, with evil or benevolent gods, monsters, and spirits
controlling the elements.
(Weather + mythology = weather-ology)
No natural phenomenon captures the imagination quite like rainbows. With
their bright colors and ethereal quality, they seem like pure magic,
completely removed from the laws of nature. It's no wonder, then, that
rainbows have been the subject of countless myths and legends since the dawn
of human civilization.
Chief among rainbow legends is the idea, popular in a wide variety of
cultures, that rainbows are actually bridges that link the natural world
with the spirit world, or the world of the gods.
One such myth is the Bilröst, a burning rainbow bridge said in Norse legend
to span between Midgard, the world of men, and Asgard, the fabled realm of
the gods. Its name literally means "shimmering path."
According to legend, only gods and those killed in battle could cross
Bilröst. An ancient prophecy foretold that one day Bilröst would shatter
under the weight of Ragnarök, the great war that would bring about the end
of the world.
Supernatural as they may seem, though, rainbows are actually created by a
perfectly natural process. They form because white light is comprised of all
colors of the spectrum. When light passes through water, or glass, it is
refracted into its component colors. Rainbows can appear any time there are
water droplets in the air and the sunlight shines from behind them at a low
angle. That means they are more likely to appear in the early morning or
later afternoon. Rainbows always appear directly opposite from the sun.
Even if a rainbow would hold your weight, you would never be able to walk on
one anywhere, because rainbows have no set physical location. A person who
appears to be standing at the end of a rainbow from another person's
perspective won't see the rainbow in the same place, but will instead see
another rainbow in a different location, opposite the sun.
While you can't actually cross into Asgard on a rainbow, and you won't find
any pots of gold at the end of one, either, rainbows are still pretty
magical, all on their own.
