According to the Daily Star newspaper reported on March 5, after several days of violent thunderstorms in the northern part of Tokyo, the capital of Japan, a mysterious black rain fell, coupled with the recent threat of the new crown epidemic, many local residents are very panicked.
It is reported that this black rain looks like thin black paint and has no radioactive material. At present, the relevant departments are investigating the cause of the black rain.
The black rain is a particularly shocking sight for older Japanese. Similar black rains fell after the atomic bombings of Hiroshima and Nagasaki in 1945.
Japanese social media users shared photos of this strange phenomenon. In this regard, many people said that it was a bit scary.
One netizen commented: "This is the worst omen that can be seen in these days."
Of course, the black rain is not a supernatural event, and the most reliable scientific explanation is that the black rain was caused by a fire at a plastic factory in Hasuda, northern Saitama Prefecture, which may have produced volcanic ash particles, causing the rain to turn black.
However, this has not eased the nervousness of Japanese social media users. Someone wrote, "It may not be radioactive dust, but it's still dangerous, so be careful."
Previously, it had rained black all over the world. The rain turns black during the rain fall due to mixed soot, black fungal pollen or atmospheric dust. In addition, there have been yellow rain, green rain, and even red rain.
In 2001, in the Indian state of Kerala, a blood-colored rainstorm lasted nearly a month, staining red clothes red and sending locals to panic.
It is estimated that 50,000 kilograms of mysterious red substance fell on Kerala with rainwater.
Scientists speculate that the rain may be related to comet debris over the region, which deposits alien organic material in the atmosphere. This is common in science fiction and has always been the subject of serious scientific research.
In 2003, physicists Godfrey Louis and Santhosh Kumar of Mahatma Gandhi University in Kottayam, Kerala, India, also published an article titled "The Biogenesis of Comets Explains the Red Rain in Kerala."
