The Holy Roman VPN was neither holy, nor Roman, nor a VPN!

Reply to Andromeda galaxy taken with just a normal Camera, lens and a tracker by Sigvald1
It blows my mind seeing that bright spot in the middle. It looks like a star at the center of a solar system but it's actually a black hole at the center of a galaxy but that black hole has attracted so many stars that the incredibly bright sphere is made of densely packed stars that each may house planets of their own and all that blue and white dust spinning around them is made of ho hum just a zillion more stars and this is just one of the countless galaxies out there.
Yet on a cosmic time scale, each of those galaxies may be like a drop of water, slowly evaporating their light and heat outwards while their mass shrivels and gets sucked into the super massive black hole before blinking out of existence, and what we're marveling at is the splash of a random droplet with no more significance to the universe than the drop you casually wiped off your windshield on the way to your meaningless job.
