... Your main research interests lie in the inter-galactic medium. ... It was not: this indicated either that intergalactic space at high redshifts is completely empty (which was very hard to understand theoretically), or that the gas was extraordinarily hot, and hence too higly ionised to absorb at the wavelengths of Ly . ... This would only show up if the inter-galactic medium was indeed very hot: strong absorption was seen, showing that there is a hot medium out there. ...
