When it's complete, a new infrared telescope in Australia will give astronomers an unprecedented glimpse of the universe. The Dynamic Red All-Sky Monitoring...

Can a galaxy build enough dust in 600-800 million years so that it is visible from earth at z = 6? That is the question. B.T. Draine is an astronomer at...

If you want to understand physics (astronomy) you have to use terminilogy independent of any human point of view. IMO Max Tegmark does not follow this idea...
