In computer-based text processing and digital typesetting, a non-breaking space, also known as a no-break space or non-breakable space (NBSP), is a variant of the space character that prevents an automatic line break (line wrap) at its position. In certain formats (such as HTML), it also prevents the “collapsing” of multiple consecutive whitespace characters into a single space. The non-breaking space is also known as a hard space or fixed space. In Unicode, it is encoded as U+00A0 no-break space (HTML:  
).

“What a phenomenon it has beenscience fiction, space fictionexploding out of nowhere, unexpectedly of course, as always happens when the human mind is being forced to expand; this time starwards, galaxy-wise, and who knows where next.”
