Conspiracy theorists blamed Russian military testing, or alien visits from outer space.
My husband loves a good conspiracy and spends hours voicing his opinion on various subjects like who murdered Princess Diana and why.
A new expedition this week made the breakthrough. The craters, some big enough to swallow ten London buses, were all in the same position of previous pingos, which are mounds of earth concealing an ice core within. Scientists discovered that cracks in the earth's core allowed heat and natural gas to escape, slowly melting the ice. The hollow space in the mounds filled with natural gas, which built up until it exploded, leaving behind nothing but a huge crater. The enormous hole is filling up with water and will eventually turn into a lake.
Russian scientists made the discovery after examining the most famous 60 metre deep crater known as B-1, which is eighteen miles from the fuel-rich region's biggest gas field.
Scientists were concerned that the erupting holes could pose a threat to Russia's gas extraction in Yamal, the name of which means the "end of the Earth".
A research team from the Trofimuk Petroleum-Gas Geology and Geophysics Institute suggested the craters could be linked to the Bermuda Triangle. Explosions under the Atlantic Ocean caused by high gas hydrate emissions are thought to explain part of the mystery of ships and aircraft disappearing.
A recent study has shown that the scent of rosemary improves the ability to list certain things in a room—rather like the game of naming all the items on a conveyor belt after a brief glimpse. Isn't nature wonderful? A huge rosemary bush grows outside my study window, begging me to use the pungent leaves. I'm off to research an easy way to make rosemary oil. Perhaps the aroma will help me recall events that happened forty years ago for my memoirs.
What do you think? Do conspiracies interest you? Do you need to improve your memory?
