What is the densest substance found in the earth?
metal osmium The densest material found on earth is the metal osmium. Still, its density pales by comparison to the densities of exotic astronomical objects such as white dwarf stars and neutron stars.
Is Mercury the densest substance on earth?
The densest liquid on Earth is the liquid element mercury, which has a density of 13.5 grams per cubic centimeter.
Where is the densest material within Earth?
The inner core The inner core is at the center of the Earth because it is the densest, made of solid iron and nickel.
Is osmium rarer than gold?
Funnily enough, Os is considered as a platinum group metal. Additionally it is much rarer than gold, about 1000 times.
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.
How dense is a black hole?
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.
| Material | ρ / g/cm3 |
|---|---|
| Black hole | 4 × 1014 |

What is the heaviest substance in the universe?
So massive stars become neutron stars – the heaviest things in the universe – and even more massive stars become black holes.
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.
What metal is 30 times rarer than gold?
platinum Along with platinum, rhodium, ruthenium, iridium, and osmium, the metal is part of a group known as platinum group metals. The bulk of the world's palladium supply comes from Russia, South Africa, the U.S., and Canada. Palladium is 30 times rarer than gold.
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.
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.
Does time stop in a black hole?
Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.
Is there anything heavier than a black hole?
Neutron stars The largest of these stars implode from their own tremendous gravitational force and become stellar mass black holes. Smaller stars that aren't quite massive enough to collapse into black holes end up compressing into ridiculously dense neutron stars.
What is the heaviest thing ever lifted by a human?
The Guinness Book of World Records (1985 edition) lists his feat of lifting 6,270 lb (2,840 kg) in a back lift as "the greatest weight ever raised by a human being".
What is in white gold?
White gold is usually an alloy containing about 75% gold and about 25% nickel and zinc. If stamped 18 karat, it would be 75% pure gold.
Is platinum actually rare?
If translated into numbers, platinum—for all of its known deposits—is considerably more rare than gold and is the rarest metal of all. And it is, truly, a gift from the heavens.
Can gold stop a bullet?
Gold Flex is lighter than woven Kevlar, Twaron and other Ballistic material. According to the manufacturer, Gold Flex offers superior bulletproof protection.
Are there titanium bullets?

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.
How long is 1 minute in a black hole?
Black hole news: Standing on edge of black hole would cause 700 years to pass in 1 minute | Science | News | Express.co.uk.
Is TON 618 bigger than the Milky Way?
In the case of TON 618, the enormous Lyman-alpha nebula surrounding it has the diameter of at least 100 kiloparsecs (320,000 light-years), twice the size of the Milky Way.
What is the most powerful thing in the universe?
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.
What is the heaviest thing in the universe?
1. Black hole in galaxy NGC 4889. This unnamed intergalactic goliath is the current heavy-weight champion. Located in the constellation Coma Berenices about 300 million light-years from Earth, it has a mass 21 billion times greater than our sun.
Can a human carry a ton?
A person exhibiting hysterical strength is reckoned to have lifted at least 3000lbs (or about a tonne and a half) – the ballpark weight of a mass-market, non-truck, passenger vehicle.
Is black gold real gold?
Because black gold contains real gold, it is automatically valuable. The more yellow gold in the jewelry, the more its value grows. Despite the black metal and additional procedures to create the black color, the value is in the natural material. The cost of black gold also depends on labor.
What is Red Gold?
Red gold is a gold alloy with at least one other metal (e.g. copper). Red gold or Red Gold may also refer to: Toona ciliata, the deciduous Australian Red Cedar tree. Red Gold, a tomato processing company based in Indiana, U.S.
