The non-British collections have been repatriated and most of the museum is now a full and honest history of Britain.
Room 4, though, is lined with time travel machines that allow the visitor to visit the museum at any point in its history by walking along a time tunnel that takes you to the desired time and gallery start point, at a quiet time of day. These machines do not fully, physically, place you in the past but rather you visit as a ‘ghost’: you cannot be seen by those living in that time, or touch anything, but you can walk around freely and take it all in as if you could.
Failing that: replicas. The V&A have many amazing replicas, such as Michaelango’s David and Isfahan’s walls and domes, that excite the the viewer; and the Natural History Museum’s most famous exhibit, Dippy, is a replica - as are many of the items on display, from fossils to whales and the dodo. If 19th and early 20th century museum workers could pull this off, imagine what might be possible now, or in the near future.
Anyway, I blank-canvassed that part because the important point is the full and honest history of Britain and a world where the west can continue to enjoy the art of the world and where the worlds where these were created can once more enjoy the originals.
