Astronomy / Space A pileup of 14 distant galaxies is set to become the most massive structure in the universe

Now with Andromeda, we are ridiculous
Ours is going to run into Andromeda as Patrick_68000 alluded to. Procedurally generate that FD!
The big bang is an interesting thing. For a indeterminate amount of time (indeterminate literally because time as such didn't exist) there was nothing*, then enough energy to create all the matter in the universe appeared or was present either at a point or everywhere at once. That energy started cooling and expanding until it got to the point where the building bocks of matter (fundamental particles like gluons and quarks) started to form. There should have been an equal amount of matter and antimatter fundamental particles which should have annihilated each other leaving nothing but there was a balance of matter left which then formed particles like electrons and protons and the rest is history as it were.
Nobody knows for sure why or how the universe exists, there are only theories (well, everything is only a theory until it's proven incorrect to be fair). We can look back to a few fractions of a second after the big bang using maths and physics but we don't know why any of it exists in the first place. Nobody knows if we ever will know why or how the universe exists either.
*it has been suggested that the spontaneous appearance of energetic particles lead to the build up of energy. These fields appeared and since there is no "place" for them to go back to, they stuck around or something like that anyway. It has also been suggested that there is a type of fundamental particle which switches between matter and antimatter states which explains the balance of matter.
It's fascinating stuff. Glad it happened though, if it hadn't then ice cream literally wouldn't exist!

My head hurts!
I don't want to bother you with my theories (what worth would it be, the gut feeling of an interested amateur?) but I never really bought into the big bang theory and phenomena like these actually have the potential to bomb the whole thing. I believe it's just a matter of time and I already bet with friends that the big bang theory would fall still in my life time (hopefully).
But at the end of the day all theories about that and why we exist at all are moot. All what really matters in the end is love and friends, no matter whether real or 'just' dreams and illusions...*
*perhaps just the shocking but typical insight of a man above 60 where the frequency at which he's losing good friends is frighteningly increasing over the last couple of years [where is it]
Bother us with them, this can be one of the few remaining bastions of intelligent discussion left on the internet
Every great scientist has at some point been an interested amateur after all! Scientists are frequently quite wrong too, when I was growing up we were told there was going to be another ice age soon... There are counter theories to the big bang, it's important to keep an open mind. Lets hear them if you want to share.
I'm sure you're right about love and friends. Knowing why we exist won't change anything for most people, I'm sure it never occurs to most people to give it any thought at all
The mark of a true scientist ... uncertain, self-doubting and unassuming.
There was a reasonable article about this (The galaxy cluster that is, not Pico's theories. ) in the Guardian on Wednesday:

Yeah; I read that. Looking backwards so far in time blows my mind...... thanks Einstein.

Based on my experience you probably want to say exactly what you mean by 'big bang theory'.
Do you mean the universe began at a singularity and has been expanding since then? May well be wrong.
Do you mean the universe was once a very great deal hotter and more dense and has been expanding since? Pretty much a certainty.
Do you mean something else? It probably needs writing down and agreeing if you want to win a bet.
I guess if time is the "Time is the indefinite continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future" from Wikipedia, if nothing at all exists, there cannot be any event taking place which could conform to that process so time as such cannot exist. Or maybe time exists as a function of the expansion of spacetime or something like that. Who knows.
You might find this interesting, I expect you have read it or similar anyway. https://medium.com/the-physics-arxi...r-like-a-solid-a-liquid-or-a-gas-5e7ed624986d
Totally understand why you wouldn't want to explain your ideas here, shame, but that's your right

What I think isn't already quite easy to explain in my native language, I really don't want to go into depth with my limited spelling abilities.
To clarify, I have no clue what actually happened in the beginning, but can imagine a few alternate possibilities mainly because I have a hard time to buy in things like "time and room did not exist before the Big Bang". In my book this is as esoteric as it possibly can be. My alternate ideas aren't less esoteric and mainly based on the believe that consciousness comes before matter. But that should do it for now as at this point most people would already put me off.
That's just to explain *why* I don't want to go further in a forum post. Sorry to disappoint you, and no, I certainly don't want to "win" a bet as it even wasn't one in a literal sense.
Oh no that's fine - I just mean to point out that it's ok to have the sort of doubts you have for example, while still thinking there was some sequence of events at some stage that counts as a Big Bang.
One note about time. What we actually *know* about time is just the method at which we measure something that in my understanding nobody exactly knows what it actually is. In my opinion time is mainly a subjective (and very volatile) feeling, while anything further is just the more and more fine grained cutting of literally nothing into very small pieces. Nothing I could easily except as a satisfiable description.
According to your Wikipedia quote about time I could as well say that when no human would exist the universe simply would not exist as well. Sounds strange, is strange, but basically follows the same logic. I think certain schools of Zen Buddhism were already touching similar considerations.
Furthermore, in the experimental world of quantum mechanics it looks like time is actually anything else than irreversible... The crucial and really interesting part would be, if and when the current strong separation between the macro and subatomic world will fall. But here I'm already in soothsayers regions again...
The universe exists only in our minds as the universe we experience, it is a construct created by our minds using the inputs from our senses, the extrapolations of mathematicians and physicists. So without humans, in a sense the universe would not exist. It is the same for all things I think according to Zen Buddhism. The universe would still exist if there were no humans, it would not change but might also exist as something else entirely in the minds of other living things observing and experiencing it.
It has been said that we are the universe observing itself. I don't know what that means but I quite like it. I suppose humans search for meaning and purpose in many things they do.
As it’s 12+ billion light years away it’s safe to say this is ‘old news’ and what ever ‘was happening’ has happened and a long long time ago at that. Astronomy is the ultimate study of history.

Inform yourself, it never hurts.

Nope, it is a consecuence of the Big Bang as the core formed 1.4 billion years after the Big Bang and the report makes sense, back then most galaxies were full of very massive and thus bright stars which explains the supernovae.
