    Using the Atacama sub millimeter telescope in that Chilean desert, one place in the world where sub mullimeters can be read at all, they have a better handle on how massive stars form and they found they form rather quickly on the galactic time scale, 75,000 years and Viola, one each massive star and they blow out pretty quickly too, a few million years and PHHT, new heavy elements injected into the clouds for the next generation of stars like ours that last billion of years and have all these nice heavy elements in them.

    The thing that gets me is the technology involved in actually getting a telescope that sensitive at those frequencies. They talk about a wavelength of 0.87 millimeters. Now 1 meter is about 300 mhz, so one mm is 300,000 mhz and 0.87 clocks in about 345 Ghz (345,000 mhz)

    That is an obscene frequency to to actual science with! It is not that far back in time that that kind of frequency might as well have been unobtanium, just a dream.

    Now it is reality, that is the lower door of Thz radiation, just below the IR band so this is a new era in radio telescopes, it is almost light waves at that frequency!

    I just found this bit about Terahertz waves and their uses:

    A new device that turns Thz to sound somehow.

    This is not science. No one has ever seen a star form. Where is the peer review testing?
