844-NEED-SCI is provided by the Science and Entertainment Exchange, an offshoot of the National Academy of Sciences, a nonprofit organization dedicated to consulting on all kind of scientific matters, with a primary focus on helping government workers and politicians understand science. Modern politicians seem to not give much of a shit about science, so fuck it, screenplay consulting it is.
So far, 844-NEED-SCI scientists have consulted on over 1,300 film and television projects. Marvel Studios are a loyal client. The goal isn't to nail the real-life science used in movies to explain fantastical bullshit. There's an understanding between writers and scientists that scripts shouldn't get bogged down by jargon, but they don't have to be loaded with scientific impossibilities and falsehoods, either. It's popcorn science. Mostly or somewhat factual is good enough. Still, I know I'm not letting facts get in the way of my script's climactic ending, in which the volcanoes start walking, no matter what some volcano nerd says.
