I tried looking up how much it would cost to use the above abstract but I see it would take a while for them to get back to you with a price estimate since options for Steemit are not really provided. I hope you realise you may be totting up quite a copyright infringement fine by now. I sure hope not! Of course, you may well have already paid up for all the abstracts and articles you have been putting up, or may even be working with a loophole I am not familiar with (please do enlighten me and make my life a lot easier too!); but then I still think you would do well to site the source; it is common academic practice, at any rate; plus I think it is conform Steemit posting rules.

In any case, here I, once again, provide the link to the original source easily enough found in the November issue of Nature Astronomy Journal, for those of us who have been gripped by the abstract above and are truly fascinated by the shape of the universe .
