Can anyone give a laymans explanation of conformal time in relativity? I tried to read Roger Penrose's book but I found it hard to grasp.Thanks in advance .(adsbygoogle = window.adsbygoogle || []).push({});

Also is a Lorentzian manifold different to a conformal manifold? A laymans explanation would also be much apprecitaed.
