- The book, to put it bluntly, is a crock. Having failed to convince the
- scientific establishment of the validity of his version of Alfven's
- model, Lerner has gone to the public to plead his case -- as if
- scientific fact was something that you vote on, rather than, well, fact.
- Lerner seems to feel that the failure of the "plasma universe" to be
- adopted has more to do with the sociology of science than the comparison
- of theory with observation or experiment. This is a convenient tack for
- him to take, because it is, IMHO, easier to construct a seemingly valid
- argument in sociology than it is in physics. However, in doing so, he
- neglects to tell the public these simple facts:
-
- 1.) Whether or not the hot Big Bang model is right or wrong, it has
- successfully explained a very wide variety of observations and experiments;
- no other competing cosmological model has been able to do this.
-
- 2.) Whether or not the hot Big Bang model is right or wrong, it has
- successfully PREDICTED (God, I'm capitalizing! Help me!) a wide variety
- of observations and experiments (yes, even experiments); no other competing
- cosmological model has been able to do this.
-
- 3.) There is not one single observation -- not one -- that falsifies the
- hot Big Bang model. People often get inflation, or cold dark matter,
- or the Einstein-deSitter (\Omega = 1) universe, or cosmic strings, or
- what have you, confused with the hot Big Bang model; various results that
- have cast doubt on scenarios such as above say NOTHING about
- the validity of the hot Big Bang model. They merely cast doubts on, or
- even falsify, specific versions of the hot Big Bang model. They would
- falsify the hot Big Bang model only if those were the only options available.
-
- 4.) The Plasma Universe is in great disagreement with observation. In some
- cases, it makes greater ad hoc assumptions than any which are made in any
- version of the hot Big Bang model (even inflation). For example, it is
- very difficult to explain the thermal spectrum of the cosmic microwave
- background outside of the Big Bang. Lerner postulates invisible filaments
- which scatter radiation from non-thermal sources in just exactly the right
- way to make the microwave background look like a blackbody spectrum to
- better than one part in 10^5. What is the physical basis for believing in
- such filaments? Who knows?
-
- In regard to #3 above, it is certainly possible to falsify the Big Bang
- model. For example, if someone detected a set of distant galaxies (with
- distances determined independantly of the Hubble law) with strong BLUEshifts,
- or if light element abundance observations strongly break ranks with Big
- Bang nucleosynthesis theory, then it's safe to say that the hot Big Bang
- model would be in trouble. But no such observations have ever occurred.
- And in his desire to discredit most of modern physics -- including,
- unbelievably enough, the Standard Model of Particle Physics -- Lerner
- really starts to scream that he doesn't know what he's talking about.
- There, he demonstrates that compatibility/incompatibility with the data
- really isn't what he's interested in.
-
- If you are seriously interested in studying this in more depth, I would
- suggest reading P.J.E. Peebles, D.N. Schramm, E.L. Turner, and R.G. Kron,
- "The case for the relativistic hot Big Bang cosmology," Nature v352,
- pp 769-776.
