Vmedvil2 Posted February 28, 2020 Report Share Posted February 28, 2020 Probably a stupid question but why is it "no good at all" ? This is excellent news, boom! Quote Link to comment Share on other sites More sharing options...
Dubbelosix Posted February 28, 2020 Report Share Posted February 28, 2020 (edited) I think he means it contradicts the big bang... But this terminology was intended to be a joke, it wasn't big, or happened in a bang it truly was a whimper transcending exponentially at a tremendous rate.

Timboo Posted February 28, 2020 Author Report Share Posted February 28, 2020 (edited) Well what was it you where getting at?What did you mean by it’s a joke? https://trib.al/l2pYAiw If we’re seeing it just now. How much longer does the shockwave hit us? And it’s expanding So did this just create a crater in the hot gas? Or did it blow a hole in the galaxy itself, With suns and star systems being caught in the blast? If so this could be the largest extinction event ever recorded Explosion - note there is a wavefront and it is expanding into pre-existing space: https://giphy.com/gifs/animation-space-explosion-l41JS0g6UPOoKV7Z6 Expansion - The image represents the 2D curved surface of a sphere that is expanding. Space is being created between the moving objects which represent photons and the static yellow dots which represent galaxies . Picture that separation as universal expansion and note that it is not expanding into pre-existing space but is actually created between the galaxies; it is necessary to ignore the area outside the sphere to get the concept: https://giphy.com/gifs/a-teoria-do-big-bang-10JybSDlaS6aOc Edited February 29, 2020 by Timboo Quote Link to comment Share on other sites More sharing options...
Timboo Posted February 29, 2020 Author Report Share Posted February 29, 2020 Just some of the questions I had Quote Link to comment Share on other sites More sharing options...
Dubbelosix Posted February 29, 2020 Report Share Posted February 29, 2020 A shock wave travels at the speed of sound, much less than the speed of light. Quote Link to comment Share on other sites More sharing options...
Timboo Posted February 29, 2020 Author Report Share Posted February 29, 2020 A shock wave travels at the speed of sound, much less than the speed of light.Ok so how long before the shockwave hits us from this 1. If the explosion was that big and took up so much space does that mean all the planets and stars in the vicinity of the burst were destroyed? 2. The article mentions that the explosion took place over millions of years but has stopped now, how do they know it stopped. Can they still see that area? thank you Quote Link to comment Share on other sites More sharing options...
Dubbelosix Posted February 29, 2020 Report Share Posted February 29, 2020 (edited) It's roughly 400 billion light years away, so I wouldn't be concerned about any shock waves. Yes they can lay waste to surrounding systems, but this one probably won't affect us for a long time even if it will, sound waves can be absorbed by interstellar objects.

Dubbelosix Posted February 29, 2020 Report Share Posted February 29, 2020 That's because the light that reached us tells us about the event 400 billion years ago, it is telling us nothing else. Quote Link to comment Share on other sites More sharing options...

So this is not something that would reach earth in our lifetimes then? Edited February 29, 2020 by Timboo Quote Link to comment Share on other sites More sharing options...

Dubbelosix Posted February 29, 2020 Report Share Posted February 29, 2020 So does that mean anything in the way of the moving shockwave is getting destroyed even now?Yes. The interstellar medium, is full of "stuff" we call cosmic dust. Quote Link to comment Share on other sites More sharing options...
Timboo Posted February 29, 2020 Author Report Share Posted February 29, 2020 (edited) Yes. The interstellar medium, is full of "stuff" we call cosmic dust.So basically it is shooting across the universe destroying anything and parts of the universe in its path.
