The chemistry behind how you make a record-breaking giant soap bubble.
The art of creating giant bubbles is more mysterious than it seems, but researchers are at last teasing apart the chemistry of thin soapy films. Emerging Technology from the arXiv. Aug 24, 2019.

# gst: how a bubble pops
<< After a bubble bursts at a liquid surface, the collapse of the cavity generates capillary waves, which focus on the axis of symmetry to produce a jet. >>
AA << show that the time-dependent profiles of cavity collapse (..) and jet formation (..) both obey a inviscid scaling, which results from a balance between surface tension and inertia forces. >>

# gst: images of hypothetical realities; expansion of bubbles in extra dimensions (of tiny, vibrating "string- like" entities)
<< According to string theory, all matter consists of tiny, vibrating "string-like" entities. >>
AA << proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension. >>
<< The researchers also show that expanding bubbles of this kind can come into existence within the framework of string theory. It is conceivable that there are more bubbles than ours, corresponding to other universes. >>
