Would be cool if they had primitive religions that believed the Milky Way to be some kind of heaven that they go to when they die. We’d be living in their heaven. Seeing supernova in the Milky Way would be like a message from heaven.

I remember driving on the highway with my kids. We could see it though the windows under streetlights. It was REALLY bright. I'm old enough to remember 'seeing' Halley's comet. My dad woke me up to go out in the yard to see a once-in-a-lifetime-event. Probably the biggest disappointment of my life. A VERY faint blob with no visible tail.

Yes, as stated in the title, it's a simulated view and not a photo. A photo like this will remain physically impossible for a long, long time. However, considering we have enough information about our own galaxy (such as its size, general orientation, and position relative to its neighbors) and that the software used to produce the images takes all of that into account when simulating the universe, it's the furthest from "just a guess" than we can scientifically get at this moment. The image is the product of a mathematical simulation using the scientific data we currently have.

Not even a few there’s a less than 1% chance that a star collision will occur when the two galaxies collide. If the distance between the stars was measured in kilometres the stars would be grains of sand.

Additionally while the stars exhibit gravity that often doesn’t put them on collision courses. Play some kerbal space program and learn how hard it is to hit a large gravitational object without just slingshotting around it.
