Astronomy 101: Exploring the Universe through True and False Questions

In summary, the conversation discusses topics related to astronomy, including supermassive black holes, inflation, and the ecliptic. The expert responds with a true statement about supermassive black holes and clarifies that "supermassive" is a subjective term. They also confirm that inflation is a real phenomenon and correct the other person's misconception about the ecliptic and the equator. The expert suggests consulting lecture notes for further clarification.

Hello all,
I am studying for an Introductory Astronomy final and I came across an old exam with a few True and False Questions


Supermassive black holes are found in the centres of large galaxies (Supermassive is tricky here, not sure on this)

Inflation is the name we give to the rapid expansion of the universe shortly after the Big Bang

(Inflation??I think False)

The ecliptic is the imaginary line in the sky that is always directly above the Earth's equator

(False, northern hemisphere yes but what about southern?)

Any help is welcome

True (well probably, we haven't looked at all galaxies)

(Supermassive is tricky here, not sure on this)
Depends on your ego I suppose but a couple of million solar masses is pretty super as far as I'm concerned.

Inflation is the name we give to the rapid expansion of the universe shortly after the Big Bang (Inflation??I think False)
Think again

The ecliptic is the imaginary line in the sky that is always directly above the Earth's equator (False, northern hemisphere yes but what about southern?)
I think you are misunderstanding the nature of an equator!
