- Given the extreme temperature and pressure that is presumed to exist
- in a quasar, is it really surprizing that they have metal lines in
- their spectra? Couldn't they fuse lighter elements into metals? I've
- heard quasars described as being the size of our Solar System but
- emitting more energy than a galaxy.
