Most move away from us, and each other.
they move by not moving.
Basically, his discovery was that most galaxies move away from us; and that the galaxies that are farther away, also tend to move away faster.

Some nearby galaxies move towards us (blueshift), some move away from us (redshift). Galaxies that are farther away all move away from us (redshift); this means that the Universe is expanding.
Edwin Hubble proved that there are other galaxies spread throughout the universe, and that these galaxies move away from each other as the universe expands. He further found that the galaxies in the outermost areas of the universe move faster that those nearer the middle, a feature in his Hubble's Law.
The general tendency is for galaxies to move away from each other, in other words, the Universe is expanding. Only in our "immediate neighborhood" will you also find some galaxies that move towards us.
Galaxies generally move away from one another.
it can move up the xylem and in both directions in the phloem
There are distant galaxies all around us - in all directions, and at varying distances.
The general tendency is for galaxies to move away from one another - the further apart they are, the faster they move away from one another. In other words, the Universe is expanding. Galaxies also have some "random" proper movement, which can be thought of as superimposed on this general expansion.
Away from us.
The force that causes galaxies to move away from one another in the universe is called dark energy.
