Oh sweetheart, the galaxy is as flat as my figure - because of how it spins, the centrifugal force causes it to flatten out. Think of it like your favorite Pizza, spinning round and round in the oven, except with a few hundred billion stars and no pepperoni. It's basic physics, dear.
No one knows that because we have not explored outside the universe. If you are thinking about the galaxy, it looks like a straight line from Earth and a circular object from outside the galaxy.
Our galaxy is visible in a night sky that is not obscured by clouds or city lights. It's a band of stars called the milky way. Because we are in it and it's flat like a plate we see it edgewise so it looks like a band of stars that kind of blur together.
Yes it would. Our galaxy is a spiral and fairly flat. When we look around our own galaxy, some parts of the sky are only thinly populated with stars but there is a line of dense stars called the milky way which is looking through the flat disk of our galaxy. An eliptical galaxy is different. It is not a flat disk but more like a ball or an egg. If we lived near the centre, no matter which way we looked, the number of stars would be about the same. If we lived on the edge of the galaxy, one side of the night sky would be filled with stars and the other side would have very few to almost none.
The milky way, and its a barred spiral galaxy.
No, the Hubble Galaxy (Messier 31, or the Andromeda Galaxy) is not the closest major galaxy to our own. The Andromeda Galaxy is located about 2.537 million light-years from the Milky Way. The closest major galaxy to us is the Triangulum Galaxy (Messier 33), which is approximately 3 million light-years away.
They are shaped like a round galaxy and they are flat
Both the Milky Way and the Andromeda galaxies are flat spirals in shape.

We don't for sure as our vantage point does not allow us to determine that. However, by viewing other spiral galaxies (Andromeda, Sombrero galaxies) we can make a calculated guess that our galaxy is shaped in the same way.Also, while we can't see the galaxy as a whole, what we can see is consistent with it being a flat disk... specifically, we can even tell that it appears to be a barred spiral galaxy.
A bulge is a tight group of stars found at the center of most spiral galaxies. The bright spot an the center of the galaxy in the picture above is the bulge. If this galaxy were seen from the side the collection of stars would create a bulge (spheroid) expanding out from the otherwise rather flat galaxy.
The Milky Way galaxy is a flat spiral - one of the commonest galactic forms in the universe.
When seen edge-on, a spiral galaxy appears as a thin, flat disk with a bulging central region. The disk is often darkened by dust lanes along its plane, giving it a more defined edge. The spiral arms are not visible from this perspective.
Both the Milky Way and the Andromeda galaxies are flat spirals in shape.
The axis plane of the solar system is tilted by about 60 degrees relative to the average plane of the Milky Way galaxy. This means that the solar system is not perfectly aligned with the flat disk of the galaxy but is slightly inclined.
No one knows that because we have not explored outside the universe. If you are thinking about the galaxy, it looks like a straight line from Earth and a circular object from outside the galaxy.
Galaxies are flat because of the way gravity and angular momentum interact during their formation. As gas and dust collapse to form a galaxy, the rotation causes it to flatten out into a disk shape. This rotation helps balance the inward pull of gravity, resulting in a flat, disk-like structure.
I don't know what you mean with "flat side". But if two black holes collide, this should produce a huge amount of gravitational wave. This is believed to be a common result of galaxy mergers.
