Elsa's Ice Palace was first shown in the movie Frozen, where it was created by Elsa. This palace was where she was supposed to live in isolation in order to protect people from her so that she can be safe from getting into trouble. If it was real, how will this castle of ice endure after our disappearance?
Timeline[]
1 day[]
As power grids fail worldwide, the ice palace is unaffected due to not being connected to a power grid. However, in Elsa's absence, the palace slowly turns from a lustrous bluish-white to a pitch black color. And it continues to get darker.
10 years[]
After ten years of Elsa's absence, the castle still stands. However, as it simply continues to get darker in color, the ice it is made out of now absorbs 100% of radiation in the visible spectrum, making a much darker color than the darkest man-made substance ever created, which is vantablack. As it is situated in a very remote and cold corner of the planet, this castle will without a doubt stand for the rest of Earth's history.
