not enuff anti-matter?

Well he didnt say how we know there is such a thing as anti-matter. If we dont see any in the universe why do we believe there is such a thing?

Also, if there are anti-rams-fans, then why dont they just explode and be done with it?

Well they discovered it through a mathematical equation, and that’s a great story. I’ll tell it later.

But particle colliders regularly create it. Just at the subatomic level.

All he was saying in the vid is that there are not huge masses of it. BUT yes it can be encountered at the subatomic level. It’s not just theoretical.

Making antimatter

We don’t find antimatter around us; in order to study antimatter it has to be made.

Transforming energy into mass

When enough energy is squeezed into a very small space, such as during high-energy particle collisions at CERN, particle-antiparticle pairs are produced spontaneously. The energy given to the accelerated particles has to be at least equivalent to the mass of the new particles in order for this to occur; the more energy that is put into particle collisions, the more massive the particles and antiparticles that can be produced.

When energy transforms into mass, both matter and antimatter are created in equal amounts.

Antimatter at CERN

Antimatter is produced in many experiments at CERN. In collisions at the Large Hadron Collider the antiparticles that are produced cannot be trapped because of their very high energy – they annihilate harmlessly in the detectors. The Antiproton Decelerator at CERN produces much slower antiprotons that can be trapped. These antiprotons can then be studied to explore questions such as: do antiparticles fall upwards?

Antimatter production in practice

At CERN, protons with an energy of 26 GeV (about 30 times their mass at rest) collide with nuclei inside a metal cylinder called a target. About four proton-antiproton pairs are produced in every million collisions. The antiprotons are separated from other particles using magnetic fields and are guided to the Antiproton Decelerator, where they are slowed down from 96% to 10% of the speed of light. They are ejected and run through beam pipes into experiments to be trapped and stored.

Small, very small quantities

Even if CERN used its accelerators only for making antimatter, it could produce no more than about 1 billionth of a gram per year. To make 1 g of antimatter would therefore take about 1 billion years.

The total amount of antimatter produced in CERN’s history is less than 10 nanograms – containing only enough energy to power a 60 W light bulb for 4 hours.
