What is the densest material we can make?
If we include manufactured elements, the densest so far is Hassium. Hassium is a chemical element with the symbol Hs and atomic number 108. It is a synthetic element (first synthesized at Hasse in Germany) and radioactive. The most stable known isotope, 269Hs, has a half-life of approximately 9.7 seconds.
What is a heavy dense material?
Osmium and iridium are the most dense metals. In other words, their atoms are packed together more tightly in solid form than other metals. With a density of 22.6 g/cm3 and 22.4 g/cm3 respectively, osmium and iridium are about twice as dense as lead, which has a density of 11.3 g/cm3.
Can you touch osmium?
Osmium tetroxide, OsO4, is highly toxic. Concentrations in air as low as 10-7 g m-3 can cause lung congestion, skin damage, and severe eye damage. The oxide, in particular, should only ever be handled by a properly qualified chemist.
How much is osmium worth?
approximately US$400/oz According to Engelhard Industrial Bullion, Osmium cost approximately US$400/oz in the US in 2018, the most recent available price. According to Osmium-Preis, since April 2017 the spot price of Crystalline osmium has significantly increased from €797/g to the current level of €1,501/g (€42,100/oz) on May 12, 2021.
Can you melt osmium?
They are also among the highest of all elements. Osmium is unworkable as a metal. It cannot be melted and shaped like most metals.
What is the densest thing known to man?
At the modest temperatures and pressures of Earth's surface, the densest known material is the metallic element osmium, which packs 22 grams into 1 cubic centimetre, or more than 100 grams into a teaspoonful.
How dense are black holes?
There is a rough analogy between a black hole and an atom. In both cases, the mass is concentrated in a tiny region at the center, but the "size" of the object is much bigger. The radius of a nucleus is (r = A1/3 x 1.7 x 10-13 cm), where A is the mass number of the nucleus….Density of Black Holes.

Is osmium bulletproof?
Osmium is not likely to make a good armor because of its weight. Its tensile strength is 1000 MPa (which sounds good), but with the density of 22.5 g/cm3, its Specific strength is only 44.4 kN·m/kg, which is lower than steel, titanium or any of the special bullet-protecting materials.
How much does a gram of osmium cost?
The osmium price per ounce is around $400, while osmiridium has fallen to approximately $21-22 for each gram or osmiridium. Osmium is the densest element known to man, and osmium nanoparticles have substantial surface areas to catalyze reactions.
Can osmium be purchased?
The crystalline, non-hazardous form of osmium, also referred to as “osmium” on this website, is available for purchase only since 2014. Due to its extraordinary rarity and high value density, crystalline osmium is used exclusively in the manufacture of premium jewellery and timepieces, and as a store of value.
Is a black hole dense?
A regular black hole — that is, one with three times the Sun's mass — with have an event horizon radius of about 9 km. That means it has a huge density, about two quadrillion grams per cubic cm (2 x 1015).
Is infinite density possible?
Infinite density can't exist because infinity anything generally implies a breakdown of the theory.
Do wormholes exist?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.
Are there titanium bullets?

Can Silk stop a bullet?
Instead of high-cost Kevlar vests, researchers have discovered that armour made from traditional Thai silk offers similar levels of protection. Tests show that a speeding 9mm bullet can be stopped dead by just 16 thin layers of silk. Use of silk to protect against injury is not a new development.
How much is 1g of osmium?
The osmium price per ounce is around $400, while osmiridium has fallen to approximately $21-22 for each gram or osmiridium. Osmium is the densest element known to man, and osmium nanoparticles have substantial surface areas to catalyze reactions.
Is osmium safe to touch?
Osmium tetroxide, OsO4, is highly toxic. Concentrations in air as low as 10-7 g m-3 can cause lung congestion, skin damage, and severe eye damage. The oxide, in particular, should only ever be handled by a properly qualified chemist.
How dense is a human?
The average density of the human body is 985 kg/m3 k g / m 3 , and the typical density of seawater is about 1020 kg/m3 k g / m 3 . (a) The average density of the human body, after maximum inhalation of air, changes to 945 kg/m3 k g / m 3 .

How heavy is a black hole?
A typical stellar-class of black hole has a mass between about 3 and 10 solar masses. Supermassive black holes exist in the center of most galaxies, including our own Milky Way Galaxy. They are astonishingly heavy, with masses ranging from millions to billions of solar masses.
Is there a white hole?
White holes cannot exist, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.
Can time be bent?
So to answer your question, time does not literally "bend". A massive object modifies the proper time interval around it such that an outside observer would see objects near the mass experience less time and spacetime intervals would have their spatial components modified accordingly.
Can titanium stop a 50 cal?
Here are some interesting videos where a 50 caliber gun shoots regular and armor piercing rounds and a 20 mm gun shoots against titanium. An inch and half of titanium does not get penetrated by the armor piercing 50 cal or 20 mm. Although with 90 degree angle there is deeper penetration.
Are Diamonds bulletproof?
Diamond Armor is certified bulletproof by NATO standards, waterproof thanks to nano-technology sealing and has an EMPA air conditioning system in-built to keep the wearer cool.
Are spider webs bulletproof?
Spider silk is highly flexible, extremely stretchable, surpasses steel in strength, and most importantly, can be formed into a mesh that would stop a bullet.
Do spiders ever run out of web?
Likely. But spiders produce silk from specialized glands in their abdomen, so they'll eventually make more.
Can you make osmium jewelry?
Jewellery. Osmium is treated like a diamond in jewellery production. It can not only be set but also brazed, glued or laser welding processed. The metal harmonizes very well in the combination with platinum, gold and silver thanks to the blue-white lustre and its high reflectivity in the spectrum of sunlight.
