What's the hardest thing in the universe?

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 is the second hardest thing in the universe?

But cubic boron nitride is still, at best, just the world's second hardest material with a Vickers hardness of around 50 GPa. Its hexagonal form (w-BN) was initially reported to be even harder but these results were based upon theoretical simulations that predicted an indentation strength 18% higher than diamond.

What is the most rare thing in space?

Now astronomers have spotted a bizarre star that may prove to be one of the rarest objects ever, with maybe as few as five or six of them in the galaxy. The object in question is known as J005311, located in the constellation Cassiopeia about 10,000 light-years from Earth.

Is a neutron star harder than diamond?

Stronger than steel, diamond, and graphene, nuclear pasta is the material that makes up neutron stars. It is formed during implosions called supernovas that compress a sun-sized object down to about the size of Montreal.

Is Obsidian stronger than diamond?

It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon's steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts.

What happens if you touch a neutron star?

Any kind of atom couldn't keep being atom anymore. So when anything tries to touch neutron star, it would be suck in by gravity and collapse into lump of neutrons and feed their mass into that neutron star. And if it collects enough mass it would collapse into a black hole.

What does a magnetar look like?

Description. Like other neutron stars, magnetars are around 20 kilometres (12 mi) in diameter, and have a mass about 1.4 solar masses. They are formed by the collapse of a star with a mass 10–25 times that of the Sun.

Are quark stars real?

Born in a supernova's blast, 3C58 seems too cool to be made of normal matter. Astronomers may have discovered two of the strangest objects in the universe--two stars that appear to be composed of a dense soup of subatomic particles called quarks.

What would nuclear pasta look like?

The resulting nuclear structures are thought to resemble pasta - hence the name - forming just inside the star's crust. Some structures are flattened into sheets like lasagna, some are bucatini tubes, some are spaghetti-like strands and others are gnocchi-esque clumps.

What is the craziest thing in space?

What is a dead galaxy?

The “dead” moniker describes the fact that these galaxies no longer have the necessary cold hydrogen gas to make stars. Without the gas, there's no clumping of matter that eventually leads to the formation of a star.

What is the hottest thing in the universe?

The hottest thing in the Universe: Supernova

The temperatures at the core during the explosion soar up to 100 billion degrees Celsius, 6000 times the temperature of the Sun's core.

What is the rarest thing known to man?

Astatine is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time. Its existence was predicted in the 1800s, but was finally discovered about 70 years later. Decades after its discovery, very little is known about astatine.

How rare is gold in the universe?

Compared to Earth's total size, that's not much gold. There is actually six times more platinum in our planet's core, which contains about 1 part per million of gold. Gold is, in fact, quite rare.

Is Wood rare than diamonds?

In the whole universe, wood is rarer than diamonds. Trees can give you oxygen and it is one of the major member of our ecosystem and after they die they gives us wood. Yes, In the whole universe, wood is rarer than diamonds.

What is inside a black hole?

What is at the center of a black hole? At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity.

Are dark stars real?

Scientists think that out of this rich environment, a new breed of star was born: dark stars. Dark stars are somewhat of a misnomer — they're not actually dark. In fact, they're likely some of the biggest and brightest stars in our universe. Yet no one has ever seen one.

Can a quark become a black hole?

Depending on the value of the gap parameter, rapidly rotating CFL quark stars can achieve much higher masses than standard neutron stars, thus making them possible stellar mass black hole candidates.

Can a black hole swallow a magnetar?

Although magnetars are incredibly powerful, they would lose the battle with a black hole. Depending on the trajectory of the magnetar, as well as the size and mass of both the magnetar and the black hole, the magnetic monster would be eaten up either whole, or slowly, piece by piece.

Which star is most powerful?

Magnetic magnetars

A magnetar is an exotic type of neutron star, its defining feature that it has an ultra-powerful magnetic field. The field is about 1,000 times stronger than a normal neutron star and about a trillion times stronger than the Earth's. Magnetars are, by far, the most magnetic stars in the universe.

Are black holes magnetic?

Technically, a black hole doesn't have a magnetic field on its own, but the dense plasma surrounding the black hole as an accretion disk does. As the plasma swirls around the black hole, the charged particles within it generate an electrical current and magnetic field.

Can you walk on a star?

No. A neutron star has such an intense gravitational field and high temperature that you could not survive a close encounter of any kind.

How big would the Earth be if it was a neutron star?

The entire mass of the Earth at neutron star density would fit into a sphere of 305 m in diameter (the size of the Arecibo Telescope).

Do we have pictures of a neutron star?

Astronomers using NASA's Hubble Space Telescope have taken their first direct look, in visible light, at a lone neutron star. This offers a unique opportunity to pinpoint its size and to narrow theories about the composition and structure of this bizarre class of gravitationally collapsed, burned out stars.
