THE THEORY OF CONTINUOUS<br />
CREATION<br />
(From chapter V <strong>of</strong> THE NATURE OF THE UNIVERSE <strong>by</strong><br />
Fred<br />
Hoyle)<br />
We must move on to consider the expl<strong>an</strong>ations that<br />
have been <strong>of</strong>fered for this exp<strong>an</strong>sion <strong>of</strong> the un i verse.<br />
Broadly<br />
speaking, the older ideas fall into two groups. One was that<br />
the universe started its life a finite time ago in a single huge<br />
explosión, <strong>an</strong>d that the present exp<strong>an</strong>sion<br />
is a relic <strong>of</strong> the<br />
violence <strong>of</strong> this explosion. This big' b<strong>an</strong>g idea seemed to me to<br />
be unsatisfactory even before detailed examination showed that<br />
it leads to serious difficulties.<br />
For when we look at our own<br />
galaxy there is not the smallest sign that such <strong>an</strong><br />
explosion<br />
ever occurred. But the really serious<br />
difficulty arises when we<br />
try to reconcile the idea <strong>of</strong> <strong>an</strong> explosion with the requirement<br />
that the galaxies have condensed out <strong>of</strong> diffuse<br />
background<br />
material. The two concepts <strong>of</strong> explosion <strong>an</strong>d condensation<br />
obviously contradictory, <strong>an</strong>d it is easy to show, provided<br />
are<br />
that<br />
you postulate <strong>an</strong> explosion <strong>of</strong> sufficient violence to explain<br />
the<br />
exp<strong>an</strong>sion <strong>of</strong> the universe, that condensations looking at all like<br />
the galaxies could never have been<br />
formed.<br />
