There are so many aspects of Hashem’s Divine Wisdom that they are uncountable.

But here is a truly remarkable one: spiders. Darwin once made an observation when he was on a ship 60 miles from land. Previously the ship had no spiders, but one day it was covered with them.

Where did they come from? One theory was that spiders expose their abdomens to the wind and release strands of silk. The wind carries the spiders via the silk – kind of like a parachute.

But it didn’t make sense. The wind wasn’t strong enough to carry them so far, and why didn’t the wind didn’t dislodge the silk?

Darwin bleibed mit a tzarich iyun.

Recently researchers discovered the answer. The earth has some 30,000 thunderstorms each day. The ground has a negative magnetic charge. The atmosphere has a positive charge.

A study by University of Bristol sensory biophysicist Erica Morley explained that when a spider releases silk, the magnetic charge of its body changes. It becomes more negative. When flexing its abdomen, the negative charge of the earth repels the spider’s body and it goes further up. It can navigate across and thus, it can fly, but with a twist.  It rides the magnetic changes.

Although wind is an important factor in the ballooning process and the miles that the spiders ultimately travel, Morley has shown that the  ballooning behavior is started by electric fields.

Wow! Mah Rabu Maasecha Hashem!

The Chovos HaL’vavos in his Shaar Habechinah states that looking at the wonders of the world and seeing the incredible intricacy of them all is, in fact, an obligation.

He writes that the unity of Hashem and can be demonstrated by examining of the wisdom in the Universe Hashem made. He writes that it is the most direct way to a true realization of Hashem’s existence.
