If you need an answer based on domain-specific knowledge, the best site to post your question is a site devoted to that domain. There are a number of SE sites which address scientific subjects.
If you can't find a suitable site, then this site may be able to help. There are a number of knowledgeable members of this community in a variety of subjects, but (for example) you'll find fewer psychologists than there will be on Psychology & Neuroscience.
You will need to couch your question in a way which is suitable for the site. On this site, we deal with problems of the English language, so won't necessarily understand or be able to provide exactly what you want, and you'll need to include more explanation than you might have to on a specialist site. However, some criteria are the same between all sites: you will definitely have to define what you mean by “more scientific sounding”, for example, in order that whichever community you ask can actually know what you want and how you will judge which answer to accept.
If you want experts in the relevant subject domain to answer, don't couch your question in such a way that it is simply migrated here!
Do thoroughly read the help pages of your chosen site, particularly to find what's on-topic; and choose tags wisely, reading the help for each tag too. Some tags, like our single-word-request tag, have quite extensive checklists to help formulate questions.
