Exempel på hur man kan använda ANTIMATTER i en mening

• In modern physics, antimatter is defined as matter composed of the antiparticles (or "partners") of the corresponding particles in "ordinary" matter, and can be thought of as matter with reversed charge, parity, and time, known as CPT reversal.
• In particle physics, every type of particle of "ordinary" matter (as opposed to antimatter) is associated with an antiparticle with the same mass but with opposite physical charges (such as electric charge).
• The advantage to this class of rocket is that a large fraction of the rest mass of a matter/antimatter mixture may be converted to energy, allowing antimatter rockets to have a far higher energy density and specific impulse than any other proposed class of rocket.
• 2010 also saw advancements in technology such as the release of the iPad, the public launch of Instagram, and the first successful trapping of antimatter.
• Scientists hope that studying antihydrogen may shed light on the question of why there is more matter than antimatter in the observable universe, known as the baryon asymmetry problem.
• He worked on such projects as space tethers and space fountains, solar sails (including Starwisp), antimatter propulsion, and other spacecraft propulsion technologies, and did further research on more esoteric possibilities such as time travel and negative matter.
• Technically, the process is not a '"catalyzed'" reaction because anti-protons (antimatter) used to start the reaction are consumed; if they were present as a catalyst the particles would be unchanged by the process and used to initiate further reactions.
• Many physicists suspect that the fact that the observable universe contains more matter than antimatter is caused by a chiral anomaly.
• The positron, the antimatter counterpart of the electron, was originally conceived of as a hole in the Dirac sea, before its experimental discovery in 1932.
• After most of the matter and antimatter was annihilated, what remained was all the baryonic matter in the current universe, along with a much greater number of bosons.
• BaBar was set up to understand the disparity between the matter and antimatter content of the universe by measuring Charge Parity violation.
• ATHENA, also known as the AD-1 experiment, was an antimatter research project at the Antiproton Decelerator at CERN, Geneva.
• Leonardo Vetra, one of CERN's top physicists who have discovered how to create antimatter, is murdered, his chest branded with an ambigram of the word "Illuminati", an ancient anti-religious organization thought extinct.
• This story also gives one of many accounts of Omega's entrapment in the antimatter universe; he uses the amputated hand of Vandekirian, a colleague opposed to Omega's plans as the system he is targeting for destruction contains sentient life, to launch his stellar manipulator.
• Shortly after, the Omutans drop fifteen antimatter planet-busters on Garissa, rendering the planet uninhabitable and killing the majority of the ninety-five million inhabitants.
• For using the power of the Green Lantern to instill fear rather than combat it, the Guardians banish Sinestro to the antimatter universe, a counterpart to the "real" universe made up of "negative matter".
• Returning to the ship in the night, the crew encounters a group of doublers being gassed to death, and act in self defense with their antimatter weapons, killing an indeterminate number of both "naked" and "soldier" doublers.
• Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current technology has great difficulty containing antimatter, which annihilates upon touching ordinary matter.
• Even though Earth-Three was destroyed in the Anti-Monitor's anti-matter wave attacks, a new Crime Syndicate (called the "Crime Syndicate of Amerika") developed in the antimatter universe of Qward, which was very different in background and power base from the pre-Crisis Earth-Three group, though same in the number of members.
• At first they suspect the Doctor and Sarah Jane of responsibility for the deaths of the expedition members, but the culprit is eventually revealed to be a creature from a universe of antimatter, retaliating for the removal by Sorenson of some antimatter samples from around the pit that acts as an interface between the two universes.
