Given how many are watching this one I predict ≥ more details! Spielberg (talk) 19:45, 10 January 2017 (UTC)

Event already occurred

If we observe the event about 1800 years later, then this stellar clash we will see in 2021-2022, already happened around 1800 years before. Is it correct?

Its the sort of thing tabloid journalists love to describe, but no astronomer will talk that way because it is effectively meaningless. We cannot say it happens until the light reaches us, so we certainly can't say it has already happened 1,800 years ago. After the fact you can say all sorts of things, but still fairly pointless. In a very real sense the event doesn't occur (or not occur) until we observe it - if that sounds too metaphysical (or quantum-mechanical), then that's a very good reason for not going down that road.

Technically speaking, in terms of Minkowski spacetime and both general or special relativity, it has not occurred yet in our frame of reference, since that event is still outside of the past light cone; the distance between us in the current moment and the merger event not being time-like, but space-like. 188.193.138.128 (talk) 20:07, 12 January 2017 (UTC)

In other words WE are the observers - relativity preçised. Schrödinger et al don't belong in this article - let's pretend "God doesn't roll dice".....Spielberg (talk) 04:47, 13 January 2017 (UTC)

That is the case for every single event in astronomy, and it is too cumbersome to mention it every time. So, astronomers have simply agreed to just stay in the timeframe observed on earth, and be done with it. Also has the great advantage that you don't have to rewrite everything each time somebody measures a better parallax or finds a better calibration for stellar distances. --Maxus96 (talk) 22:15, 14 June 2017 (UTC)

Third-Party Program Demonstration/Simulation

• I had added a simulation, on the main article, but someone removed it.

• Earth to KIC 9832227
  Earth to KIC-9832227.webm Earth to KIC 9832227

• I was hoping to educate and inspire future astronomers/cosmologists/astrophysicists about SpaceEngine and this star system.
• Nothing replaces real data from real stars ... but humans can get a rough idea from a demonstration/simulation.
• I'm currently involved in a forum discussion on SpaceEngine's website regarding correct measurements/calculations on each star and the orbits.
• Once the matter is settled, I can easily record another video which would be more accurate.
