On tense edit

Hi Stanford96, I noticed your edit, replacing "... which is marked by general relativity and black holes becoming mainstream..." with "... which was marked...". I fully agree with this edit, but I was wondering whether replacing it with "... which is marked by general relativity and black holes having become mainstream..." couldn't have fixed the tense problem as well? (Just curious -- note that English is not my first language). Cheers - DVdm (talk) 16:07, 4 December 2010 (UTC)Reply

Either way is fine. However, "having become" is arguably a little more cumbersome. Stanford96 (talk) 17:12, 12 December 2010 (UTC)Reply
