Costliest substance in the world - $62.5 Trillion per grams

When we talk about the most costliest items in this world then precious objects comes into our mind like Gold, Platinum, Diamond etc. If we are from technical  background then we talk about radioactive isotopes like uranium, Iridium etc. Yes all these are precious and very costly.

But there is one substance which is so difficult to extract that with the present technology, it will take approx 1 billion years to extract just 1 gm of this substance. As per estimates conducted by NASA, the total cost to extract 1 gm of this substance is 62.5$ trillion dollars. Can you imagine it !!!!!!

So what is this substance, why it is so costly and why it is so important for human species !

This substance is nothing but "Antimatter". Antimatter is nothing but opposite of Matter. If a mater has negatively charged electrons and positively charged protons then Antimatter has positively charged electron and negatively charged electron.

antimatter annihilation


In theory, a particle and its anti-particle (e.g., proton and antiproton) have the same mass as one another, but opposite electric charge and other differences in quantum numbers. A collision between any particle and its anti-particle partner is known to lead to their mutual annihilation, giving rise to various proportions of intense photons (gamma rays), neutrinos, and sometimes less-massive particle–antiparticle pairs.

Annihilation usually results in a release of energy that becomes available for heat or work. The amount of the released energy is usually proportional to the total mass of the collided matter and antimatter, in accord with the mass–energy equivalence equation, E = mc2.

CERN houses a machine called the Antiproton Decelerator, a storage ring that can capture and slow antiprotons to study their properties and behavior.

In circular particle accelerators like the Large Hadron Collider, particles get a kick of energy each time they complete a rotation. Decelerators work in reverse; instead of an energy boost, particles get a kick backward to slow their speeds.


Just a handful of antimatter can produce a huge amount of power, making it a popular fuel for futuristic vehicles in science fiction. Antimatter rocket propulsion is hypothetically possible; the major limitation is gathering enough antimatter to make it happen.

There is currently no technology available to mass-produce or collect antimatter in the volume needed for this application. However, a small number of researchers have conducted simulation studies on propulsion and storage. These include Ronan Keane and Wei-Ming Zhang, who did their work at Western Reserve Academy and Kent State University, respectively, and Marc Weber and his colleagues at Washington State University. One day, if we can figure out a way to create or collect large amounts of antimatter, their studies might help antimatter-propelled interstellar travel become a reality.
