Go to Brittle hollow and fly with your ship inside the the tower. and wait for the planet to crumble, then you will go into black hole along with the tower , and come out of white hole. Be sure to have the tower marked in your map, as it will float a bit far away after coming from white hole.
Use your jetpack and go to the tower, now since there is no gravity you will be will able to explore the tower fully
Honestly this is one of the best games of all time.. and GOTY 2019
