I didnt mean that the legions were sent to another galaxy. The tyranids had to enter the milkyway at some point so a sizable force might have been able to hold them back for a time and as for the iImperium not officaly dicovering the tyranids until the m40 it could have been covered up by the Emperor. He did try and keep chaos hidden so why not the tyranids.
