Is it a balloon? /s
“One possibility is that X7’s gas and dust were ejected at the moment when two stars merged,” Ciurlo said. “In this process, the merged star is hidden inside a shell of dust and gas, which might fit the description of the G objects. And the ejected gas perhaps produced X7-like objects.”
This is pretty interesting, so much ejection due to a merger that the light is no longer visible.
Space stories like this always melt my mind because this has all happened already , but we're observing it now.
- koheripbal 4y ago> this has all happened already , but we're observing it now. In a real sense, it only happens when the light from it reaches you. Reality propagates at the speed of light.
- pixl97 4y agoCausality is fun. The order in which things happen can be different for different observers. With light on earth humans don't generally experience this because of the small distances involved. But you can design an experiment with sound where 3 observers are placed in a large field and 3 loud noises are made, and each observer will tell you the noises occurred in a different order.

- prettyStandard 4y agoI think about this often. Is this reality's "update loop"[0]? [0] https://gameprogrammingpatterns.com/game-loop.html https://gameprogrammingpatterns.com/game-loop.html
- Eupraxias 4y agoMy head tilted at the title. I suppose "Mysterious object WAS dragged into the black hole a super long time ago..." doesn't have as much sizzle.

I'm having difficulty parsing your "in a real sense". Are you refering to Relativity here or something deeper like 'subjective reality'?
- ben174 4y agoI can't make any sense of this. It has happened over there - so it's happened. How does it make a difference where I am standing. I'm not talking about my reality. I'm talking about reality. Things which have taken place and nothing can change that.
- andrewflnr 4y agoThat's because it actually doesn't make sense. They're confused, not you. Source: college physics.
- worewood 4y agoThere is no reality because there is no central authority to dictate what has happened and when/where. Your reality IS the reality.
- mistermann 4y ago"The"? "Is"?
- adharmad 4y agoBut how do you know that it has taken place without the light reaching you? Without the light (or radiation), all you can say is that "something may have taken place everywhere".
- tcgv 4y ago> But how do you know that it has taken place without the light reaching you? Things happen without us knowing about it, and without light from such events ever reaching us. We don't need to know it has happened for it to have happened.
- ben174 4y agoI don't. But that doesn't matter. If it has happened it has happened. Whether I know about it has no bearing on reality (not my reality).
