Everything would become condensed into one dense point. This is known as the singularity, which is believed to be the starting point of the universe according to the Big Bang theory. By reversing the galaxy motion and going back in time, everything would eventually converge into this singular point of extreme density and temperature.

Moving away from us. This is a key observation that led to the development of the Big Bang theory. Astronomers have observed that galaxies are moving away from each other and from our own galaxy, the Milky Way. This expansion of the universe is one of the main pieces of evidence supporting the idea that the universe began with a Big Bang.

Water. Galaxies primarily consist of gas, stars, and dust. Water is not a primary component of galaxies, although it can exist in molecular form in interstellar space within galaxies.

Circular. Galaxies can have various shapes, but circular is not typically a term used to describe the shape of galaxies. The common shapes of galaxies are irregular, spiral, and elliptical.
