More than 100 years ago, an enigmatic explosion devastated 80 million trees in a Russian forest. Today, researchers say the mystery known as the Tunguska event may be solved.

They say new evidence suggests a comet -- not a meteor as previously thought -- was behind the explosion. And, as the BBC reported, they're pointing to clouds that form thousands of miles away at Earth's polices to explain the theory.

Scientists claim these "noctilucent" clouds -- formations that are similar to what was seen after the Tunguska event -- reach the poles because water vapor appears to be quickly traveling in two dimensions, rather than three. The phenomenon, experts believe, happens when something like a magnetic field constrains the vapor, forcing it to move extremely fast in the remaining two dimensions.

Hopefully that will put the UFO business to rest, but probably not.

I am not sure I understand the "2 Dimension" talk?

Are they referring to 2 Vectors (Lets just say x and y) and alleviating z?

Sorry for my ignorance, but my mind is pretty heavily wrapped around this one.... :pity:

Good question, I'm not sure exactly how they mean it, but your example is a good answer.

The way I took is that the clouds moved say, from the prespective of the observer, east to west and from closer to the ground to higher (or lower) to the ground but not away of towards the viewer -- or some variation on that theme.

yes in other words it traveled on one plane instead of a series of different planes.
