I was creating anti electrons in my mom's garage and using atom smashers to, eventually, create beams of antimatter. Antimatter is the opposite of matter.

This resulted in the predominance of matter over antimatter in the present universe.

I didn't have to explain to him that I was experimenting with antimatter.

For every piece of matter, there's a counterpart which is made out of antimatter.

Iridium is used in particle physics for the production of antiprotons, a form of antimatter.

The biggest limiting factor in the large scale production of antimatter is the availability of antiprotons.

This device cannot, however, contain antimatter that consists of uncharged particles, for which atomic traps are used.

But isotopes, particles of electricity, antimatter, neutrinos, the conversion of mass to energy that's E mc 2 gamma rays, transmutation.

The presence of the resulting antimatter is detectable by the two gamma rays produced every time positrons annihilate with nearby matter.

During the period of baryogenesis, when the universe was extremely hot and dense, matter and antimatter were continually produced and annihilated.

Antimatter in the form of charged particles can be contained by a combination of electric and magnetic fields, in a device called a Penning trap.

Other collider experiments there's one that's going to take place next summer at CERN have the possibility of creating something called strangelets, which are kind of like antimatter.

But isotopes, particles of electricity, antimatter, neutrinos, the conversion of mass to energy that's E mc 2 gamma rays, That ancient dream that had always eluded the alchemists was achieved through these same theories that explained starlight and other ancient mysteries, and new, unexpected phenomena.
