Bizarre Stone Can Walk

Have you ever seen the stone itself can walk like animals? At the Racetrack Playa, National Park, Death Valley, California, United States have a stone like this, it is also shaped like a stone does not always have "feet" but it will move itself. Hundreds of pounds of stone can also be shifted a few hundred meters, there is no animal or human that move. In hundreds of years, as this phenomenon has caused arguments in the scientific community.





"Racetrack Playa is a dry lake, located in Death Valley National Park, California, United States. At the time there was little rain water, when the summer rainy season or less, roller akan river cracked into small pieces under the blazing sun.

The former movement stones is very short, the friction on the left not in soil, in mud, no more than one inch in front of the stone table shifted ground around 1-2 inch thickness. Former friction is not regular but clearly visible. Which is strange in the 4 - 5 where the former is a flat stone moved. Many scientists think this may occur may be due to strong winds and the combination and the influence of icing on the surface of desert sand that encourage the movement of a stone. This interpretation however can not be maintained, he can not explain why a stone of various sizes will be side by side with the speed and direction of movement is different. In addition, the calculation of physics also do not support the above interpretation is required because the wind speeds of at least several hundred miles per hour can move the stones in the desert, and a strong wind may blow and the few small stones, but through the strength of what the weight of stone hundreds of pounds can move in mysterious?

Thunderstorms form when Viewing from the Outside Space Station

this Wilma storms picture taken on the date 19 October 2005 by the station crew when the NASA space travel at an altitude of 222 miles above the earth permukan. At that time hurricanes Wilma holds a record as the most powerful storms in the Atlantic with wind speeds reaching 175 mph. Wilma is being seen in the Caribbean Sea, 340 miles southeast Cozumel, Mexico.

NASA Space Station External taking photos at the time in Mexico and the bay are likely to move west towards the rising month. Emily at the time entered in category 4 strength with winds near 155 mph and moving from west to northwest through the Caribbean.
