... Your main research interests concern neutral hydrogen. ... That means that there must be enormous quantities of gas lying around, waiting for the chance to collapse under its own weight into lumps and form stars and galaxies. If we could actually observe this gas, as it moves around and assembles itself into lumps, we would be directly observing the process of galaxy formation. ... Optical astronomers seem to think that they can observe galaxy formation by taking optical images. ... In galaxies. ...
