Eli5: how do the pillars of creation just stay the same shape out in space for so long and how did it all accumulate in that area?
In: 7284
Because the pillars are absolutely massive, they are changing but because they are so big the change happens very slowly, it takes decades to see even small changes in its shape but the pillars are traveling through the galaxy just like the stars are.
Just to put it into perspective on how big the pillars are they stretch about 4-5 light years across, one light year is roughly 9.4 trillion kilometers
