" Such a portrayal was often used as a means to silence voices critical of elite interests. With the Soviet Union's collapse, proponents of the propaganda model have argued that the functionality and credibility of anti-communism has been fundamentally compromised . Proponents state that new, more functional anathemas have arisen to take its place. Chomsky and Herman argue that one possible replacement for anti-communism seems to have emerged in the form of "anti-terrorism". Summary Chomsky and Herman summarize their theory thus: "A propaganda model has a certain initial plausibility on guided free-market assumptions that are not particularly controversial. In essence, the private media are major corporations selling a product (readers and audiences) to other businesses (advertisers). The national media typically target and serve elite opinion, groups that, on the one hand provide an optimal "profile" for advertising purposes, and, on the other, play a role in decision-making in the private and public spheres. Model Rocket Scale The national media would be failing to meet their elite audience's needs if they did not present a tolerably realistic portrayal of the world. But their "societal purpose" also requires that the media's interpretation of the world reflect the interests and concerns of the sellers, the buyers, and the governmental and private institutions dominated by these groups (p. "

" Therefore, it would be possible to "overtake" a neutrino, choosing a reference frame in which its direction of motion is reversed without affecting its spin (making it right-handed). Since then, physicists have revised the Standard Model to allow neutrinos to have mass, which make up additional free parameters beyond the initial 19. A further extension of the Standard Model can be found in the theory of supersymmetry, which proposes a massive supersymmetric "partner" for every particle in the conventional Standard Model. Supersymmetric particles have been suggested as a candidate for explaining dark matter. Although supersymmetric particles have not been observed experimentally to date, the theory is one of the most popular avenues of research in theoretical particle physics.
