All the heat the others have taken for insisting otherwise can now, apparently, be airily waved away:
The fact is that energy conservation only works at a particular location, not for the expanding Universe. You might have heard the expression that “there’s no such thing as a free lunch.” While that might be true here on Earth, that reasoning doesn’t apply to the expanding Universe. In fact, if ideas like inflation and the multiverse are correct, perhaps the real truth is that the Universe is the ultimate free lunch. In these trying times, this is one thing we can all be thankful for.

Is he looking forward to a free lunch future? Worth wondering.
