"But today's leading gravity theorists are not downcast. To find out where they believe their subject is heading, Chown has talked with several experts, including the Canadian Nima Arkani-Hamed, a highly regarded theoretician based at the Institute of Advanced Study in Princeton. Arkani-Hamed is optimistic that quantum theory and the basic theory of relativity are together leading us to a quantum theory of gravity and of the other fundamental forces of nature. He says experts are "pretty universally agreed" that their current best understanding of space and time is "doomed"." https://www.theguardian.com/books/20...s-chown-review

The basic theory of relativity is leading us to a quantum theory of gravity but the current best understanding of space and time is doomed! Bravo, Nima Arkani-Hamed! You are a very subtle practitioner of doublethink:

"Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them. The Party intellectual knows in which direction his memories must be altered; he therefore knows that he is playing tricks with reality; but by the exercise of doublethink he also satisfies himself that reality is not violated. The process has to be conscious, or it would not be carried out with sufficient precision, but it also has to be unconscious, or it would bring with it a feeling of falsity and hence of guilt. Doublethink lies at the very heart of Ingsoc, since the essential act of the Party is to use conscious deception while retaining the firmness of purpose that goes with complete honesty. To tell deliberate lies while genuinely believing in them, to forget any fact that has become inconvenient, and then, when it becomes necessary again, to draw it back from oblivion for just so long as it is needed, to deny the existence of objective reality and all the while to take account of the reality which one denies - all this is indispensably necessary. [...] It need hardly be said that the subtlest practitioners of doublethink are those who invented doublethink and know that it is a vast system of mental cheating. In our society, those who have the best knowledge of what is happening are also those who are furthest from seeing the world as it is. In general, the greater the understanding, the greater the delusion ; the more intelligent, the less sane.."
