If the earthly sanctuary is a replica of the heavenly sanctuary, can there be death in heaven?

Please excuse what appears to be a bit of a confused question...I am trying to make sense of something that I simply do not fully understand in my own mind. The question is therefore very difficult for me to word as I would like. After the Jews came out of Egypt and God led them to Mt Sinai, God said to Moses.. *Then have them make a sanctuary for me, and I will dwell among them. Exodus 25.8 New International Version* *the Lord gave Moses blueprints for one of the most mysterious structures ever built? ... a unique temple that represented God’s dwelling place among His people. Its overall design and services showed this nation of freed slaves a three-dimensional panorama of the plan of salvation https://sdarm.org/publications/bible-study-guide/ptoc/lesson-14* In studying a visual image of the layout of the Tabernacle that Moses was asked to have built, the alter of sacrifice where the lamb was slain and offered as a burnt offering was in the courtyard https://www.goodseed.com/diagram-of-the-tabernacle-and-basic-layout.html Where are the laver and alter of sacrifice located in the heavenly sanctuary model that the earthly one is based upon as given to Moses? How do we interpret the relationship between the heavenly and earthly sanctuary, the services, and the plan of salvation...ie, is the courtyard of the heavenly sanctuary actually this earth where Jesus was sacrificed? Finally, does that therefore mean that there can be no death in Heaven because sin only exists on this earth? Given the idea that at least part of the heavenly sanctuary might very well be on earth (the courtyard containing the alter of sacrifice and laver), is it possible that in fact the entire heavenly sanctuary is a metaphor for the plan of salvation itself rather than a single literal place/structure in heaven.
