| Jul 29, 2019 at 21:08 | comment | added | Steve Linton | Is it possible you are thing about much more speculative ideas like two "universes" colliding (two branes, or two regions where inflation ceased independently). In most cases, these scenarios would result in all of space filling with massive amounts of energy and fundmental physical laws changing so that matter as we know it would be impossible. | |
| Jul 29, 2019 at 21:03 | comment | added | Wayfaring Stranger | Doubling the mass density of a star forming region might give rise to an unusual number of supermassive stars. These have lifetimes on the order of millions of years, and make a large bang when they go. You'd have to be near the thing when it goes, or aligned with a jet to have problems. -Still not likely. | |

| Jul 29, 2019 at 19:20 | comment | added | AtmosphericPrisonEscape | Nobody dies. In the event of a galaxy merger, there are barely any close encounters between stars. Space between stars is mostly empty, even if one increases the local stellar density by a factor of two. This series had it wrong. | |
