1 Even though the name of the archangel is not mentioned in 1 Thessalonians, Jude 9 makes reference to Michael the archangel.. 2  Even Billy Graham wrote in his book  Angels: Godâs Secret Agents , He [Michael] must stand alone, because the Bible never speaks of archangels, only the archangel..
Sonic booms generate enormous amounts of sound energy, sounding much like an explosion; typically the shock front may approach 100 megawatts per square meter, and may exceed 200 decibels. 10 log (100 x 10^(6)/ 10^(-12)) = 200 dB.
The sonic boom we hear caused by an airplane flying at Mach 1 usually takes the form of a âdouble boom. The first boom is caused by the change in air pressure as the nose of the plane reaches Mach 1, and the second boom is caused by the change in pressure that occurs when the tail of the plane passes and air pressure returns to normal.
