Izzie and Dr Becky are untangling the cosmic web - the large scale structure of the universe - with help from Dr Chiara Mingarelli from Yale University. What the heck is it? What do we know about it? And can we use gravitational waves to "see" it? Plus, Dr Robert Massey is on hand to answer your questions. Got a question for the team?
