Letter: On the trail of the missing dark matter (2)

From Julian Higman, Wantage, Oxfordshire, UK

Peebles is correct to say that physics is incomplete. It probably always will be. So, have we got the universe right?

Well, the short answer must be that we don’t know. But there are good reasons for suspecting that we haven’t, and that the big bang theory is wrong. As we get more and more telescopes of varying kinds up into orbit, not just around Earth but around the sun too, the picture will become clearer.
