일반상대론에서 굽은 공간의 비유로서 얇은 고무판의 적절성 = The Validity of the Rubber Sheet as an Analogy of Curved Space in General Relativity

다국어 초록 (Multilingual Abstract)

In this paper, we examine the validity of the analogy of rubber sheet for curved space through the comparison of two surface equations. The Poisson equation and variational method were used for the comparison. The misconceptions from the analogy and possible demonstration were introduced for the instruction in the class.

국문 초록 (Abstract)

일반상대론에서 굽은 공간의 비유로 흔히 무거운 공을 놓은 처진 얇은 고무판을 비유로 든다. 실제로 이 곡면의 모양이 일반상대론의 굽은 공간의 모양과 얼마나 일치하는지 두 곡면의 식을 구하고 비교하여 비유로서의 타당성을 검토한다. 그리고 비유로부터 나타나는 오개념과 비유를 활용한 다양한 실험들을 소개하여 학교현장에서 학생지도에 도움이 되고자 한다.
