Are Supermassive Black Holes Really at the Center of Galaxies?

AI Thread Summary
Supermassive black holes are generally accepted to exist at the centers of large galaxies, although not all galaxies have been observed. The concept of inflation refers to the rapid expansion of the universe after the Big Bang, and it is considered true. The ecliptic is often misunderstood; it is not directly above the Earth's equator but rather relates to the plane of Earth's orbit around the Sun. Clarifications on these topics can enhance understanding for astronomy studies. Accurate comprehension of these concepts is crucial for success in astronomy courses.

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)

Depends on your ego I suppose but a couple of million solar masses is pretty super as far as I'm concerned.

Think again

I think you are misunderstanding the nature of an equator!
 
What do your lecture notes say about these things?
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
