宇宙膨胀的解释:锚定概念和误解

Interpretations of cosmic expansion: anchoring conceptions and misconceptions

Markus Pössel

摘要:

在本科或高中阶段教授宇宙学需要简化和类比,这不可避免地会使教师接触到至少一种对膨胀宇宙的教学解释。到目前为止,最流行的解释认为,在膨胀的宇宙中,星系是静止的,而空间本身会膨胀,从而导致宇宙膨胀的特征是距离不断增加。另一种相对论爆炸解释把宇宙膨胀看作是(相对论)星系运动的一种模式。本文的目的是讨论两个竞争的解释,从潜在的学生的先入之见的角度来看,同时考虑到有益的锚定概念和潜在的有害的先入之见,可能会导致误解。

英文摘要:

Teaching cosmology at the undergraduate or high school level requires simplifications and analogies, and inevitably brings the teacher into contact with at least one of the pedagogical interpretations of the expanding universe. The by far most popular interpretation holds that galaxies in an expanding universe are stationary, while space itself expands and thus causes the growing distances that characterize cosmic expansion. The alternative relativistic explosion interpretation regards cosmic expansion as a pattern of (relativistic) galaxy motion. The aim of this article is to discuss the two competing interpretations from the perspective of potential student preconceptions, taking into account both beneficial anchoring conceptions and potentially harmful preconceptions that can lead to misconceptions.
