A black hole lurked at the center of our Galaxy
Original Title:
Keywords: demonstrator astronomy black hole sagitarius A milkyway centre of our galaxy salsa J kepler Description:
On this particular subject, black holes, students usually have the idea that since a black hole does not emit light, it cannot be detected. But books talk about black holes as a sure thing – so how do scientists infer the existence of a black hole? It is also frequent for students to think about a black hole as an entity that will swallow everything around it – so they think that the whole universe will end up being pulled into a black hole. Another common educational problem is that students tend to separate science subjects in a way that they do not associate Astronomy with Physics. They have difficulties in applying what they learn in Mechanics, for example, to the motions in the sky. Moreover, they might have doubts in applying the same laws to astronomical situations as the ones they apply here on Earth. |
