How long does it take to explore the museum?

Couple of hours should be good

There is no time limit

Yes one thing about going there you do it at your own pace there's no rush through but you could do it under 35 minutes if your time was short,But as long as 3 hours if you like to read everything there

1-2 hours

Around 2 hours.

You move at your own pace...as slow or as fast as you want to go
