What is earth's strongest material?
Graphene is known as the strongest material on earth. However, research is going on across the globe to find stronger materials. You can read about Nanotechnology in India – Origins, Uses, Developments in the given link.
Palladium microalloy glass is believed to be one of the most durable materials on the planet, thanks to its combo of toughness and strength. It's also extremely elastic, bending when subjected to stress instead of shattering.
Topping the list, graphene is the strongest materials known to humans. The transparent material is composed of a single layer carbon atom arranged in a triangular lattice and it's the basic structural element in charcoal, graphite and carbon nanotubes.
It is well-known since the late 20th-century that there's a form of carbon that's even harder than diamonds: carbon nanotubes. By binding carbon together into a hexagonal shape, it can hold a rigid cylindrical-shaped structure more stably than any other structure known to humankind.
It's a tardigrade—the most 'indestructible' animal on Earth. Also called water bears, tardigrades can survive up to 30 years without food, live in volcanoes, and endure the vacuum of space. Researchers say they could even survive an asteroid impact like the one that led to the extinction of the dinosaurs.
Tungsten measures between 8 and 9 on the Mohs hardness scale. (Diamonds are a 10 - the highest.) Due to their extreme hardness, Tungsten Rings will hold their shape and shine longer than any ring on the market.
The tensile strength and elastic modulus of graphene are 125Gpa and 1.1tpa, respectively, and its strength is 100 times that of ordinary steel. Bags made of graphene, which can hold about 2 tons of weight, are by far the strongest material known.
“Graphene is stronger and stiffer than diamond, yet can be stretched by a quarter of its length, like rubber,” said Andre Geim, who shared the 2010 Nobel prize in physics with Kostya Novoselov for their discovery of graphene.
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material.
The hardest mineral on the scale, diamond, is given a hardness rating of 10. Since obsidian is rated at 5-6 on Moh's Hardness Scale, it is not stronger than a diamond; it's softer than a diamond.
What is the weakest thing in the world?
Though gravity holds planets, stars, solar systems and even galaxies together, it turns out to be the weakest of the fundamental forces, especially at the molecular and atomic scales.
Yes it is. Even the hardest bedrock is still not as hard as diamond.
Are Diamonds Stronger than Steel? A diamond is smoother than steel since its molecules are held more tightly together. However, a diamond is not stronger than steel. Steel is also denser than diamonds because each molecule weighs much more than a carbon atom alone.
Titanium is highly valued in the metals industry for its high tensile strength, as well as its light weight, corrosion resistance, and ability to withstand extreme temperatures. It's as strong as steel but 45% lighter, and twice as strong as aluminum but only 60% heavier.
Because diamonds are the hardest natural material on Earth, only other diamonds can cut them. Diamond-bladed edges are used on the equipment to make the cuts. In some cases, special lasers may be used to assist in this process.
While there may not be many naturally-occurring materials out there that are stronger than diamonds, certain man-made metals like tungsten and steel have a higher tensile strength. That means a direct hit with an ordinary hammer can absolutely break a diamond.
There is nothing that can scratch a diamond except another diamond. A mineral like talc, on the other hand, is a 1 on the scale. You could scratch it with any hard material, even your fingernail. Natural talc is one of the softest minerals in the world.
If you hit it with enough force, or hit it in just the right way, almost anything can break—that is, separate into pieces. Even the hardest materials we know of—including diamonds, wurtzite, boron nitride, moissanite, and corundum—can be fractured.
If something is so strong that it is impossible to damage it, you can say that it is indestructible. Titanium is virtually indestructible.
Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
What can cut tungsten?
While other metals can be removed with a wedding ring cutter, tungsten rings are a type of ring that can only be "cut" with vice grips or any kind of locking pliers.
Every material is bullet proof, as long as you have enough of it. Alternatively, any material can be penetrated by a bullet, provided it is thin enough. Tungsten is very dense and pretty hard. Both are usually good properties if you want to stop a bullet.
What some may find odd or shocking is that tungsten rings are not indestructible. Tungsten carbide rings can break! If a tungsten ring is dropped on a hard surface, it can break or crack.
In the real world, extraordinary strength can occur via science. A person can become stronger, tougher, and more physically powerful than would seem humanly possible when using enhancements such as doping, substances and training.
Scientists have found a mineral stronger than diamond Scientists have found a mineral stronger than diamond. They say lonsdaleite could be used to fortify industrial tools like drill bits and saw blades - AND teach us about the evolution of earth.
A dung beetle is not only the world's strongest insect but also the strongest animal on the planet compared to body weight. They can pull 1,141 times their own body weight. This is the equivalent of an average person pulling six double-decker buses full of people. Now that's strong!
Following this, the material cracks radially outwards and ultimately disintegrates. Researchers from Rice University found that 300 layers of graphene – which is, after all, at most 100nm thick – were capable of stopping such microbullets entirely.
Graphene is intrinsically nonmagnetic as all the outer electrons in carbon hexatomic rings are perfectly paired to take shape in σ- and π-bonds. All the efforts to make graphene magnetic are carried out to break the symmetric bonds to release the unpaired electrons and generate net spins.
Amedeo Bellunato, PhD candidate at the Leiden Institute of Chemistry, has developed a method of cutting graphene into smaller fragments using a diamond knife. He can then construct nanostructures from the fragments. Graphene is a honeycomb structure of carbon atoms just a single atom thick.
Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur. The law of conservation of mass states that matter cannot be created or destroyed.
What metal Cannot be destroyed?
As it stands, it is not possible to destroy gold on a molecular level with any naturally occurring substance on earth. Pure gold is virtually indestructible. It will not corrode, rust or tarnish, and fire cannot destroy it.
Researchers claim the material, known as Proteus, cannot be cut. In fact, it's so tough it destroys any tool that attempts to slice into it.
Obsidian has been used across history to make weapons, implements, tools, ornaments, and mirrors. Because of its conchoidal fracture (smooth curved surfaces and sharp edges), the sharpest stone artifacts were fashioned from obsidian.
At What Temperature Do Diamonds Melt? If you heat the diamond in the open air, it will begin to melt and burn at around 700 degrees Celsius (1,292 degrees Fahrenheit). Burning a diamond without oxygen, however, will make it change into graphite (a crystalline form of carbon) before transforming into a fluid.
Lava will destroy most furniture and platforms, except Obsidian and Stone Platforms.
“This is a great fact: strength is life; weakness is death. Strength is felicity, life eternal, immortal; weakness is constant strain and misery, weakness is death.”
In terms of the number of humans killed every year, mosquitos by far hold the record, being responsible for between 725,000 and 1,000,000 deaths annually.
Strictly speaking, humans are the smartest animals on Earth—at least according to human standards.

Graphene remains the strongest material ever measured and, as Professor Hone once put it, so strong that "it would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap.”
What is hardest metal on earth?
- While there are several parameters for categorizing metals in terms of hardness, chromium (687-6500 MPa) is the hardest known metal on the planet.
- It should not be confused with Tungsten, which has the highest tensile strength of any metal.
- Tungsten in its pure form is typically brittle and can shatter on impact.
These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.
Mercury is a liquid at room temperature. It has the weakest metallic bonding of all, as indicated by its bonding energy (61 kJ/mol) and melting point (−39 °C) which, together, are the lowest of all the metallic elements.
The heaviest metal is osmium, which has, bulk for bulk, nearly twice the weight of lead. The specific gravity of gold is about 19 1/4, while that of osmium is almost 22 1/2. Osmium is also the most infusible of metals, remaining unaffected by a degree of heat capable of causing platinum to run like water.
* Caesium is the softest metal with the Mohs hardness of 0.2.
