Astronomy/The Universe


Between galaxies, is there matter or is it just empty space?

Hello Russell...
The space between galaxies is not just empty space, although it's much more empty than within galaxies. Between galaxies vast clouds of gas and dust often exist, along with an occasional planet or star that has been hurled into intergalactic space by gravitational forces with their home galaxies.
