What is the hardest thing on earth?
Scientists have calculated that wurtzite boron nitride and lonsdaleite (hexagonal diamond) both have greater indentation strengths than diamond.
Source: English Wikipedia.
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world..
What is the unbreakable thing in the world?
The tiny tardigrade has been named the world’s most indestructible species after scientists discovered it is the only creature that will survive until the Sun dies.
Can acid destroy a diamond?
No, acids cannot dissolve diamonds, for the simple reason that a diamonds carbon atoms are too tightly packed together for the Hydrogen ions to be able to dissolve the substance.
What is the weakest element?
Diamond is the hardest known natural substance and for that reason it is often used in drill bits. For the weakest element, I would probably go for helium – one of the noble gases. It is very light and unreactive.
Are teeth alive?
Teeth are alive. Therefore, teeth can die. Root canal therapy (endodontics) can reclaim teeth after they have died. In order to understand this, you must first understand the anatomy of a tooth.
What can destroy a diamond?
Steel and other rocks can be used to easily crush a diamond. Like I said earlier, super heating a diamond can set it on fire, and even throwing diamonds into your furnace will burn them all up.
Are teeth harder than diamonds?
Using the scale of mineral hardness developed by German mineralogist Frederich Mohs in 1812, tooth enamel ranked 5 out of the 1-10 values. Diamonds ranked 10 (hardest) and plaster of Paris ranked only 2 on the Moh’s scale. Tooth enamel was also found to be harder than limestone and most shells containing calcite.
Can a bullet damage a diamond?
Diamonds fail as an armour material on a number of grounds. At low energy impacts a diamond armour plate might well be able to deflect a projectile without any real damage, but it would be at risk of shattering if the projectile energy exceeded a critical point.

Can you melt a diamond?
Diamond isn’t easy to melt, which is why the scientists used Sandia’s Z machine, the world’s largest X-ray generator, to subject tiny squares of diamond, only a few nanometers thick, to pressures more than 10 million times the atmosphere’s pressure at sea level. … The diamond melted then re solidified.
Is Titanium stronger than a diamond?
Titanium is not stronger than a diamond. In terms of hardness, Titanium is not harder than a diamond either. … Diamond strength is around 60 GPa. As for the hardness scale, titanium is 36 Rockwell C, while diamond is 98.07 Rockwell C.
Is air stronger than fire?
Fire is not evil, but is made stronger by either air or earth, considering that wood and coal are earth. … Air is seen as stronger than water or earth for the same reason. It all comes down to purity. Air is more pure than water, water more pure than earth and fire more pure than earth.
Are teeth a bone?
Teeth and bones look similar and share some commonalities, including being the hardest substances in your body. But teeth aren’t actually bone. This misconception might arise from the fact that both contain calcium. More than 99 percent of your body’s calcium can be found in your bones and teeth.
Is glass harder than teeth?
Tooth enamel is harder than steel, but breaks much easier. Tooth enamel is mostly hydroxyapatite, which is a mineral form of calcium phosphate. The apatite group of minerals scores a five on the Mohs hardness scale; which makes enamel the hardest biological material.
