Letter: On the strange idea that space-time can remember (1)

Published 9 July 2025

From Faith Anstey, Dalguise, Perth and Kinross, UK

Some believe religion promises immortality. Others trust their descendants to provide it, and a few hope their works of art will earn it. However, the existence of a non-physical “soul” is fraught with problems, while physical descendants and creations can take you only so far(21 June, p 32).

However, according to Florian Neukart’s hypothesis, actions, once performed, can’t be unperformed. They are now history and can’t be erased from the memory of space-time. Might this be how our legacy persists?
