Have they detected it? Have scientists finally zeroed in on those strange rumblings we’ve been reporting for years, sounds that for some are a matter of prophecy (an omen)?

Not, it seems, quite yet. “Solar-powered balloons launched into the earth’s stratosphere have recorded a series of mysterious rumblings, and scientists can’t pinpoint their origins,” reported Live Science last week.

“The noises, detected by specialized instruments at 70,000 feet above the earth’s surface, are known as infrasound because they are so low-pitched they are inaudible to human ears.”

Those are not quite the sounds we reference, which have been clearly audible (and recorded on media such as YouTube). But it’s interesting. For as the article went on:

“Picked out from among a wash of hidden low-frequency sounds — including thunder, ocean waves, rocket launches, cities, wind turbines, and even planes, trains, and automobiles — the strange infrasounds have so far defied explanation,”

The History Channel reports that on January 2017, a sound was heard here on earth, a blaring one that was recorded in a man’s backyard in Lewisburg, North Carolina. Nothing in sight to account for it.

“A chill went down my spine,” said this fellow, Dillard Dickerson. “I felt very in shock. I didn’t really know what to think.”

From ABC News: “A series of minor tremors recorded on the Danish Baltic island of Bornholm Saturday has puzzled scientists, who now say they were caused by ‘acoustic pressure waves from an unknown source.’ At first the tremors were thought to have been caused by earthquakes. Then, seismologists theorized that they originated from controlled explosions in Poland, more than 140 kilometers (nearly 90 miles) to the south.  On Monday, the Geological Survey of Denmark and Greenland, an official body that monitors the underground, said the tremors were ‘not caused by earthquakes, but by pressure waves from an event in the atmosphere.’ However, they came from ‘an unknown source.’”

Machinery in factories? Secret tunneling? Distant traffic? Apocalyptic signs?

Revelation Chapter Nine? “Then the fifth angel sounded, and I saw a star from heaven which had fallen to the earth; and the key of the bottomless pit was given to him. He opened the bottomless pit, and smoke went up out of the pit, like the smoke of a great furnace; and the sun and the air were darkened by the smoke of the pit. Then out of the smoke came locusts upon the earth, and power was given them, as the scorpions of the earth have power.”

How about the supernatural: Many reports of strange lights in the sky (and stranger creatures) are often accompanied by similar booms, hums, and rumblings (along, perhaps more tellingly, with the odor of sulfur).

Oh, yes, our era! 

Rochester, New York. Bristol, England. A groaning sound in Connecticut (haunting folks seeking slumber). “The hum is a worldwide phenomenon,” M. J. Barnia, who studies such matters, told History. 

Seismic vibrations? Aliens? A geologic shift that portends quakes? 

Simply, does earth cry out in pain?

Said the 1990 prophecy: “In the period also will be a warning that involves not fire from the sky but fear of fire from the sky, and strange loud rumblings.” 

Add “hums” to the mix.
