Diamond is hardest substance is it true ?

 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 program run on the computer gave us this data.
