Yes i have a poster that explains about the expansion (and cooling) of the universe here from an Open University course and an updated standard model poster from a more recent open learn course.

Well the BBC article headline is "Scientists detect biggest explosion since Big Bang - BBC News" which like people, here have pointed out, wasn't even an explosion as such. Which is why I was looking for a more scientific source of information. https://www.bbc.co.uk/news/science-environment-51669384 Even in the BBC article the first few paragraphs seem to mention "The huge release of energy" then "eruption" then the co-author "I've tried to put this explosion into human terms" So yeah no wonder the headline is how it is, "explosion" sounds more dramatic than science. Even the dailymail made it out to be a explosion https://www.dailymail.co.uk/sciencetech/article-8051079/Biggest-explosion-Universe-Big-Bang-detected.html Mind you given their doom laden coverage of Corona virus, it does not come as a surprise to me that. I will try and make sense of the paper, even if it is more complex. Paul

Thanks this is what I am looking for, so I can read the proper report / paper on this, not a bbc interpretation of it. the title of the above paper is "DISCOVERY OF A GIANT RADIO FOSSIL IN THE OPHIUCHUS GALAXY CLUSTER" which is a big difference, I have seen other references that seem to suggest this is the biggest since the big bang, and bigger than the big bang, so yeah finding the proper paper also cuts through all this. I did a search for Astrophysical Journal and found the site I posted earlier when asking, That area of space seems rather interesting but we could probably say that about other regions of space for different reasons. Thanks, Paul,

So does that mean that if we saw a supernova tomorrow, then Betelgeuse have exploded 640 years ago. If it is 640 light years away that is. Paul

Scientists detect biggest explosion since Big Bang - BBC News https://www.bbc.co.uk/news/science-environment-51669384 This sounds interesting, i am guessing this is being observed from the Southern Hemisphere. I am trying to find the paper this BBC article has mentioned on https://iopscience.iop.org But am unsure exactly what to search for. So I would be grateful for any help please. Granted these science papers are not really for the layman, as such, as they are somewhat complex. It would be good to try and read the actual paper rather than just the report written for everyone else. However doing searches for Ophiuchus yields a few papers that suggest this region is a really interesting area of space, I am currently undertaking an OU Open Learn course on Orion which is also covering the lifespan of stars, very interesting as a topic, I need to crack on with it though, but OpenLearn is open ended so I just login and do a little bit more when I have some time. thanks Paul

I have seen Water refereed to as Hydrogen Hydroxide too, but more of a joke / humour. Paul

I think you can make a sort of plastic / rubber sufur substance by heating then putting in to cold water so the sulfur reforms in a different structure, then it will act as a sort of rubbery substance,
