Q&A: Cosmology
This is a great new discovery of gas in the IGM. Is
there going to be a new estimate of the average
density of the IGM now? I think it is a lot denser
than current theory allows.
The density varies from place to place, but the average seems to be
coming out in the predicted range, namely 10 to 100 hydrogen nuclei per
cubic meter, with a small percentage of heavier elements mixed in.
