Antimatter: The Most Expensive Substance in the Universe, 1gram is equal to 62 Trillion Dollars

 Antimatter: The Most Expensive Substance in the Universe

In the grand quest to understand the cosmos, humanity has uncovered some truly bizarre and awe-inspiring phenomena—but few are as mysterious and potent as antimatter. With a price tag of $62.5 trillion per gram, antimatter is not only the most expensive material on Earth—it’s arguably the most precious substance known to science. To put that into perspective, just a few grams would exceed the combined GDP of the entire planet, currently estimated around $110 trillion. So, what exactly is antimatter? Why is it so rare, and what makes it so valuable?

Antimatter is, quite literally, the mirror opposite of matter. Every particle in the universe has a corresponding antiparticle. For instance, the antiparticle of the electron is the positron, which has the same mass but a positive charge. When a particle and its antiparticle meet, they annihilate one another in a burst of pure energy. This annihilation process is what gives antimatter its almost mythical appeal.

It’s the ultimate fuel—100% efficient energy conversion. While nuclear fission and fusion convert only a small fraction of mass into energy, matter-antimatter annihilation converts all of it. The famous equation E=mc² shows just how powerful this is. One gram of antimatter reacting with one gram of matter would unleash roughly 180 terajoules of energy—enough to power New York City for a full day. 

The astronomical cost of antimatter isn’t due to scarcity in nature (although it’s incredibly rare) but because of the enormous complexity in producing and storing it. Antimatter doesn’t exist in nature in usable quantities. Cosmic rays occasionally produce antiparticles, and some are formed in high-energy environments such as supernovae or near black holes—but gathering them is practically impossible.

Instead, scientists manufacture antimatter in particle accelerators like those at CERN, where particles are smashed together at near-light speeds. Occasionally, collisions produce antiparticles like positrons or antiprotons. But the production rate is incredibly low: creating even a nanogram of antimatter would take billions of dollars and years of continuous operation Then there’s the containment problem—antimatter cannot touch regular matter, or it will annihilate instantly. Scientists use magnetic traps to suspend antimatter in a vacuum, a technique that is both energy-intensive and unstable.

The $62.5 trillion-per-gram estimate comes from calculating the operational costs, infrastructure, and energy needed to produce even a few nanograms. At present, we’ve only been able to create a few dozen atoms of antimatter at any given time—and only for fractions of a second.

Antimatter has long fascinated writers and filmmakers. From powering warp drives in Star Trek to being used as a weapon of mass destruction in Angels & Demons, antimatter is often portrayed as the ultimate sci-fi energy source. And in many ways, the science backs up those ambitions—if we could somehow produce and store antimatter in usable quantities, it could revolutionize space travel.

Imagine interstellar spacecraft propelled not by chemical rockets or even nuclear reactors, but by matter-antimatter engines capable of reaching relativistic speeds—a dream that brings us tantalizingly close to deep-space exploration and even colonizing other planets. One gram of antimatter could theoretically take a spaceship to Mars in under a month, reducing months of travel and exposure to cosmic radiation.

Antimatter in Science Fiction and Reality

Medical Applications: Antimatter in the Hospital

While interstellar journeys remain a distant dream, antimatter is already being used in one of the most crucial fields: medicine. Positrons, the antimatter counterparts of electrons, are used in Positron Emission Tomography (PET scans), a vital imaging tool for detecting cancer, heart disease, and brain disorders. In PET scans, a small amount of radioactive material that emits positrons is introduced into the body. When the positrons meet electrons in the body, they annihilate, producing gamma rays that can be

 detected to form detailed internal images.

This is one of the only practical and affordable uses of antimatter today—but it demonstrates the potential for future medical breakthroughs, especially in targeted therapies for diseases.
