How has our universe evolve? Cosmologists have through decades come up with various models that talk of the universe’s growth from a few hundred thousand years after the Big Bang to the present day.
But, a recent finding claims an otherwise different model, which if correct, will lead scientists rethink their models dramatically! A US physicist claims that the tiny temperature variations seen in maps of the cosmic microwave background are not proof of stars, galaxies and other large-scale structures’ growth from density perturbations in the early universe, as been commonly thought.
He claims that the variations are in fact caused by hydrogen atoms in our own galaxy!
The WMAP scientists had to (by the present model) carefully subtract known contributions from physical processes in the Milky Way, but, if Verschuur is to be considered correct, the correlating hydrogen emissions are supposed to be originating from an unidentified process.
Noticing the WMAP-recorded temperature variations tend to coincide with radio emissions from the Milky Way’s neutral hydrogen, Gerrit Verschuur told physicsworld.com,
So many data are daunting and users of the all-sky LAB survey still tend to extract only the data for the small area they are interested in... I had been working with the data over a large area.
Although everyone doesn’t agree with the US physicist’s inferences, if he is proved correct, it will demand a thorough rehearse and both extensive and intensive rethinking on the existing models of the evolution of the Universe.
