About expansion of the universe, redshift in an observed distant object means itís moving away. Okay. Part of the redshift, however, caused by atomic hydrogen in space, about one atom per cubic centimeter. Astrophysicists take that into account when making their calculations. Otherwise, they would get an exaggerate figure for how fast something is moving away from us. But what about H2? Atomic hydrogen (H1) is easy to detect with radio astronomy, but molecular hydrogen is silent and normally cannot be detected in space. And for some reason the possible existence of H2 is space is ignored. It means that people say the universe is expanding but really donít know if they donít know how much hydrogen in its most stable state is out there. Well, H2 can be observed in places where itís hot and has been with the Infrared Space Observatory (ISO). And the authors of the original article (E. A. Valentijn and P. P. van der Werf, 1999) pointed out that if there is H2 in space scientists have no business claiming an expanding universe, Big Bang, etc. Granted, the amount of H2 hasnít been determined. So thereís no figure to replace zero molecules per cubic parsec. Itís probably five to 10 molecules per cubic centimeter, but fewer than five, if confirmed, would be sufficient to prove a lot of what it taken for granted today to be absolute nonsense. At least in the face of the evidence they could say, ďI donít know.Ē Instead, theyíre also going so far to say that galaxies beyond the Hubble horizon are moving away from us faster than the speed of light.
This article explains it quite clearly. You can see the authorís credentials at the bottom of the page, which is old. He has passed away since this was posted. But there are more recent papers on this to be found on the Web.
Astronomers with truckloads of credentials might like to sling mud at anyone holding this point of view, but still, how can anyone claim thereís no H2 is space, while admitting to one atom per cubic centimeter of H1, not to mention that fact that hydrogen atoms tend to pair off and mate for life? Maybe theyíre right, but the most respected scientists used claim quite loudly, ďRocks canít fall from the sky!Ē
