Friends, If I ask you to name the hardest substance in the world, The hardest material in the universe. You will think of Diamonds. This answer is correct with regard to the earth, but not for the universe. Recently, scientists have discovered a material that is harder than diamonds. It is known as Lonsdaleite. It is found in meteorites. When the meteors enter the earth's atmosphere they heat up Due to this friction of the air, the meteor's outer layer gets burnt, but the inner parts remain cool. Diamond is hardest substance But when the meteors crash into the earth, so much pressure is exerted even to the very core, that it is much more than any natural process on earth. This pressure compresses the graphite into such crystalline structures that are harder than diamonds. Loansdaleite is believed to be able to bear 58% more stress compared to diamonds. But this hasn't been physically tested by scientists yet, because this is such a rare material. Instead, a simulation
In Uttrakhand, about5000 meters above sea level, there is a lake of skeletons . Submerged in this lake, You find skeletons the identity of which is a mystery. How did they die? Where did they come from? This lake was discovered in 1941 by a British forest ranger. There are several theories. A group of Japanese soldiers from World war two died because of the cold there. After investigating, the skeletons were found to be much older. Skeleton Lake of India Another theory claims that it was a spot of ritual suicide. But these skeletons are spread throughout the lake. They aren't gathered in one place. In 2004, a team of European and Indian scientists, carbon dated these to find that they are from 850 AD. Creaks were found on the back of some skulls, revealing that these people were hit from the back. Another theory emerged that there might have been a devastating hailstorm. People might have been hit by huge hails suffering fatal injuries. But recently, another mysterious discover
