Not at all.  Velikovsky's "speculations" conflict with some of our most
basic scientific knowledge in a variety of disciplines.  See the appendix
of _Broca's Brain_ by Carl Sagan for a detailed, dispassionate analysis
of Velikovsky's ideas.  Cosmology, and in particular theories of the
early universe, proceed from a basis of well-tested science.  We *do*
have evidence with which to check these theories: the 3K background
radiation, isotope ratios, the distribution of matter in the universe,
etc.  Observational capabilities in these areas are improving steadily.

If you already know the answers, you're asking the wrong questions.

There are actually several good reasons.
1.  Strong electromagnets must withstand the enormous bursting forces
induced in their coils.  The new superconductors, being ceramics, are
brittle, and therefore ill-equipped to withstand these forces.
2.  The new high-temperature superconductors have a critical current
density that is still about 100 times too low for this application.
3.  A low temperature (liquid helium range) is highly desirable in
particle accelerators because it minimizes collisions between the
accelerated particles and stray gas molecules.  (The residual gas
in the beam path freezes out.)
4.  Magnets and cooling amount to only about 5% of the projected cost
of the SSC.

What?  It may be that the life expectancy of a healthy adult has not
increased much.  But because of the dramatic decline in infant and child
mortality, the life expectancy of a newborn is much greater in a modern
society than in a primitive one.

In any case, mortality is not the sole measure of health!  You might
also consider what modern medicine has done to alleviate physical
suffering.

Ay, there's the rub.  It seems that human happiness is keyed as much
to expectations as to "standard of living".

Still, if you wish to return to a pre-scientific way of life,
I say go right ahead.
