There are three states of matter: solid; liquid and gas.

All matter such as solids, liquids, and gases, is composed of atoms. Therefore, the atom is considered to be the basic building block of matter. However, atoms are almost always grouped together with other atoms to form what is called a molecule.

Classify matter as an element, compound, homogeneous mixture, or heterogeneous mixture with regard to its physical state and composition.

Solids

The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates.

An international team of researchers has successfully produced a Bose-Einstein condensate (BEC) in space for the first time. A Bose-Einstein condensate is a state of matter occurring after gas atoms with very low density are chilled to very near absolute zero and bunch up to form an extremely dense quantum state.

One leading hypothesis is that dark matter consists of exotic particles that don’t interact with normal matter or light but that still exert a gravitational pull. Several scientific groups, including one at CERN’s Large Hadron Collider, are currently working to generate dark matter particles for study in the lab.

When antimatter and regular matter touch together, they destroy each other and release lots of energy in the form of radiation (usually gamma rays). If it’s a small amount, it’s totally safe.

Humans have created only a tiny amount of antimatter. A gram of antimatter could produce an explosion the size of a nuclear bomb. Making 1 gram of antimatter would require approximately 25 million billion kilowatt-hours of energy and cost over a million billion dollars.

When equal amounts of matter and antimatter collide, they are annihilated. The two would be annihilated and turn into pure energy. Of course, the gravity of a black hole is so immense that nothing, not even light can escape. So all energy would just be turned instantaneously into more black hole.

If at all you need to buy antimatter, you need to buy it from a particle physics laboratory like CERN or Fermilab, which I doubt might sell it to you. These labs make antimatter in small quantities and have a special storage systems to contain them.

But what is antimatter? Due to its explosive nature (it annihilates when in contact with normal matter) and energy-intensive production, the cost of making antimatter is astronomical. CERN produces about 1×10^15 antiprotons every year, but that only amounts to 1.67 nanograms.

Antimatter Housing can be purchased at Galactic Trade Terminals.

The heaviest antimatter created so far was Helium-3, with two protons and one neutron. The breakthrough was made by a team of international scientists working on the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory of the US Department of Energy.

The Big Bang should have created equal amounts of matter and antimatter in the early universe. But today, everything we see from the smallest life forms on Earth to the largest stellar objects is made almost entirely of matter. Comparatively, there is not much antimatter to be found.

But if you wanted to destroy an entire planet, it would only take a small amount of antimatter to do the job: just 0.00000002% the mass of the planet in question. For much larger planets such as Jupiter, you’re going to need about 2 x 10 36 joules, which means 2 trillion trillion trillion joules of energy.

An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon. Annihilation requires and converts exactly equal masses of antimatter and matter by the collision which releases the entire mass-energy of both, which for 1 gram is ~9×1013 joules.

Antimatter is nearly 10 times more powerful than the most powerful nuclear weapons, due to the fact that nuclear reactions only release 10% of their energy created as the blast itself. Antimatter, being antimatter, gives all 100% as the explosion.

Whenever antimatter meets matter (assuming their particles are of the same type), then annihilation occurs, and energy is released. In this case, a 1 kg chunk of the earth would be annihilated , along with the meteorite. There would be energy released in the form of gamma radiation (probably).

When the antimatter bomb explodes, it will erupt into an enormous fireball, creating a 10 km (6 mi) wide column of dust, shooting straight up into the sky. Next up would be the mushroom cloud reaching 65 km (40 mi) into the atmosphere.

PHYSICISTS have made a key measurement of anti-atoms, and found that they look just like atoms. Antimatter particles are the same as matter particles, but have the opposite electrical charge. …

Who knows its worth? Right now, antimatter – with a price tag of about $62.5 trillion per gram – is the most expensive substance on the Earth.

A matter-antimatter annihilation (the technical term) would be very, very bright, assuming a large enough quantity (closer to . 01 grams than to 1 atom). When matter and antimatter annihilate, the product is photons of various wavelengths. Some would be visible light, reaulting in a blinding flash.
