Readers question quantum mechanics and more

Pushing limits

Stanford physicist Monika Schleier-Smith’s atom experiments could be a boon to quantum computing and possibly offer insights into black holes, Elizabeth Quill reported in “Monika Schleier-Smith leads elaborate quantum conversations” (SN: 10/12/19 & 10/26/19, p. 37).

Reader Ray Bryan asked if these experiments could shed light on how to unite quantum mechanics and gravity.
