WHAT HAPPENS IF YOU ENTER THE MILKY WAY GALATIC CORE

The galatic core, the central bulge of the Milky Way, is a region very densely populated by stars. It is a dangerous place- Stars regularly get close enough to each other to disrupt their respective solar systems. Stellar explosions are not uncommon, spreading radiation across large sections of space, sterilizing planets, killing nascent life. But if you happen upon a planet on which you can stand and look up at night, the sky would likely be quite spectacular, so full of stars you could probably read by starlight alone. Contrary to common myths, the supermassive black hole called Sagittarius A is not the core of the Milky Way, nor does its gravity dominate even in the bulge. Sure, it weighs in at a whopping 4 million Suns, but the bulge itself weighs on the order of a hundred billion Suns, completely dwarfing the black hole. This region where Sagittarius A rules is a tiny region of space within the Milky Way bulge, and it does not even necessarily coincide with the Milky Way's center-of-mass. Elsewhere, you see stars, you see gas, you see rapid star formation, lots of activity that, fortunately, is absent from the region where our solar system resides. If you were somehow transported to the Milky Way bulge and stood on the surface of a planet looking up....you would see nothing rapid at all. On human scales, the sky would appear mostly static and unchanging. If you observed the sky (with an incredible number of stars) meticulously for years, you might see a few stars relative to the rest (these would be the nearest to you, with so-called proper motion) but that's just about all of it. Most of the violent activity people associate with galactic bulges, with the rare exception of the occasional stellar explosion, take place on time scales that are far beyond human lifetime.
