Letter: Letters: Insider dealing

Published 6 July 1991

From MICHAEL JARMAN

I wonder if someone could explain something that has been puzzling me
for some time. We are told that if one gets enough matter in a sufficiently
small space it collapses to form a black hole from which nothing can escape.
We are also told that all the matter in the universe was created at the
same time at a single point. This seems, to me at any rate, like absolutely
A1 conditions for the formation of a magnificent black hole. How is it then
that the universe is flying apart?

Michael Jarman Bristol

John Gribbin writes: The universe may very well be a black hole – but
we are inside it.
