How will we see the Arsh on qiyamah (& how will Moses hold 1 of its pillars) when its so big? Might Allah shrink it to scale with earth or something?

The Kursi extends over the universe (Quran 2:225) and hadith says it is like a ring in a desert compared to the Arsh, so how then will we see the latter on Qiyamah and how can Musa (as) hold onto one of its pillars (Bukhari)?
