What is antimatter and how to create antimatter

Antimatter/antiparticle is just a normal matter/particle but with opposite charges. For instance, a negatively charged electron has a positively charged antiparticle called the positron. Similarly, an antiparticle of the positively charged proton is called an antiproton with a negative charge. When matter and antiparticle come close together, then they annihilate and transform their masses into energy.

Matter and antiparticles both created during the big bang but in today’s world antimatter is very rare. Scientists are still figuring out why?

Antimatter is successfully produced at the large Large Hadron Collider operated by CERN. When very high-energy particles collide, they produce both particles and antiparticles simultaneously and in equal amounts. The energy given by high-energy particles is equivalent to their combined masses. The more the energy, the higher will be the masses of particles and antiparticles.

How to produce antimatter

Antimatter is produced at CERN, can not be trapped as they annihilate very very quickly due to very high energy. On the other side, antiproton can be trapped and separated from Antiproton Decelerator, where their speed reduced from 96% to 10% of the speed of light.

But producing it is very costly. To produce 1g of antimatter you will need a trillion dollars of money.

0.001 kg x (300,000,000 m/s)2 = 90,000 GJ = 25 million kWh

In order to produce 1 gm of antiparticle, you require 25 million kWh. That would cost over 100 trillion dollars. The second problem is, the storing of antiparticles is really really difficult. With the current technology we have, we can store only a few atoms of antiparticles at a time. To overcome these problems, we need advanced technology and engineering.
