If the Mayan Prophecy Is True, Just How Might
It All End on Friday? Scientists Foretell the Cataclysms That Could
Bring on Doomsday
They say it won't happen, at least not on Friday, but in the event
the Mayan prophecy of the end of the world is right, scientists
have foretold a raft of bloody and catastrophic fates for us all.
Dark comets, famine, super-volcanoes, catastrophic climate change,
and a plague of cancers are just some of the ends that could fulfill
Astrophysicist Professor Jocelyn Bell Burnell, who discovered pulsars,
believes the most likely disaster that could pencil Doomsday into
Friday's diary is a black comet.
Such an end would match that of the dinosaurs who after walking
the planet for about 165 million years homo sapiens has been around
for a mere 200,000 years were killed off by a 10km asteroid or
comet that slammed into the planet.
Professor Bell Burnell believes if the world as we know it is to
end on December 21 it would have to be a dark comet that strikes.
Dark comets have little of the ice and snow that most comets have,
and a lot more dust which makes it much more difficult to spot them
as they speed through Space.
'Comets normally are big, dusty snowballs. A dark comet has not
much snow and a lot of dust. They are much harder to get a handle
on,' she said.
The collision itself, except for those near the point of impact,
would be unlikely to be fatal to the world's population but it would
throw up so much dust into the atmosphere that billions of people
could expect a slow death.
Huge quantities of dust would bring on an 'eternal winter' in which
the sun would be obscured and crops around the world would fail,
leading to mass famine.
Dave Rothery, a volcanologist at the Open University, foretells
a similar end but he thinks the death-bringing dust would be put
into the atmosphere by a supervolcano.
More than 240 cubic miles of molten rock and debris are blasted
into the sky by super-volcanoes.
Much of it would remain in the atmosphere as volcanic dust which
would, just as with a massive asteroid or comet, block out the sun
and cause famine.
'It would put so much ash and sulphur dioxide into the atmosphere
that photosynthesis may break down," he warned.
A similar, albeit less devastating, even took place in 1816 when
a volcano in Indonesia erupted and put so much dust into the atmosphere
that it became known as 'the year of no summer'.
