23 May 2024. Birth of universe’s earliest galaxies observed for first time
----
For the first time in the history of astronomy, researchers at the Niels Bohr Institute have witnessed the birth of three of the universe's absolute earliest galaxies, somewhere between 13.3 and 13.4 billion years ago. Illustration: NASA
#
The discovery was made using the James Webb Space Telescope, which brought these first 'live observations' of formative galaxies down to us here on Earth.
#
Through the telescope, researchers were able to see signals from large amounts of gas that accumulate and accrete onto a mini-galaxy in the process of being built. While this is how galaxies are formed according to theories and computer simulations, it had never actually been witnessed.
#
"One of the most fundamental questions that we humans have always asked is: 'Where do we come from?'. Here, we piece together a bit more of the answer by shedding light on the moment that some of the universe’s first structures were created. It is a process that we’ll investigate further, until hopefully, we are able to fit even more pieces of the puzzle together," concludes Associate Professor Gabriel Brammer.

how do they know they have found the "center" of the universe from which the "big bang" occurred?

In the flat, infinite, cold cosmic vacuum, there are billions times billions of galaxies
in various stages of evolution: the later stages and, as has been discovered,
at stage of "three earliest galaxies in the universe"

[Atla]

-Imp

No one claims something like that.. it would be a rather new hypothesis.

[alan1000]

Atla, can you develop your point? Because it seems counter-intuitive... if these galaxies really represent a stage of the universe so young, elementary arithmetic implies that they must have been relatively that much closer to the centre; there wouldn't have been much outside of that light-year radius!

That would have been a reasonable conclusion 150 years ago, before Einstein did away with Newtonian absolute space and time. There is no "centre".

We also can't see past the Big Bang in time. We can't even see the Big Bang itself, if there ever was such a thing. So a centre from which the Big Bang occured would be just some wildly speculative stuff.

[Age]

how do they know they have found the "center" of the universe from which the "big bang" occurred?

-Imp

Some claim that the 'big bang' is what caused/created the Universe or what was the start/beginning of the Universe. So, it is an absolute impossibility for there to be a centre of the very thing, that is; the Universe, to already have been existing, from which the 'big bang' could have occurred.

Obviously, the cause or creator of some thing cannot come 'after' the caused/created thing began.

one may just make reference to the 'big bang' being at the 'center' of the Universe, but this in absolutely no way means that there is a centre of the Universe or that there could even be one.

Also, and obviously, the so-called 'big bang' had to come from somewhere, and from something, else.

So, absolutely any and every claim that what is being 'looked' at here are the 'earlier stages' of the Universe, Itself, is a complete and utter False, Wrong, Inaccurate, and Incorrect presumption only.

[Age]

Atla, can you develop your point? Because it seems counter-intuitive... if these galaxies really represent a stage of the universe so young,

But, what would make any sane person think that there was was even a 'young stage' of the Universe to begin with?

Why were there so many human beings who believed that the Universe evenv began?

When the answer to this question is known and well understood, then why all of those adults, back then, used to believe things, which were blatantly False and Wrong with hindsight, then this is when human beings, really, began to start moving and progressing forward.

Until then they would just keep trying to argue and/or fight for their pre-existing beliefs. No matter how Wrong and/or False those beliefs were, or still are.

elementary arithmetic implies that they must have been relatively that much closer to the centre;

When did this perception, and belief, that there is a 'center of the Universe' come to exist, and from where also, exactly?

Sounds like one could be trying to argue from another belief like the one that the earth was at the 'center of Universe'.

Who even claims there is an 'actual center'?

there wouldn't have been much outside of that light-year radius!
[/quote]

One could also try to claim that there would not have been much outside of that half light-year radius, or quarter, or tenth, or multi-trillonth percent of light-year radius as well. But if one did, then they would just be exposing and showing how Truly closed their views and beliefs are here.

Hey, I have a great idea! Why don't we just say that some mystical entiry - let's call it "God" - created the whole thing? Problem solved!

The problem begins: “How did He/She/It create the whole thing? "

25 June 2024. We are closer than ever to finally proving the multiverse exists
One hundred years ago, we discovered there were other galaxies beyond our own. Now, we might be on the verge of another discovery: that there are other universes
/By Miriam Frankel/
-----
We think our universe contains everything that exists, has ever existed and will exist in the future. But this might not be the case: there are many ways other universes could exist.
#
One is that we could be a single part of a branch of infinite universes known collectively as the multiverse. These universes might have appeared shortly after the big bang, they might be hiding in extra dimensions or they could pop into existence whenever a quantum property goes from a cloud of possible states to a single reality.
#
Multiverse ideas gained scientific weight in the 1980s with the invention of inflation, a period when the early universe suddenly expanded. Inflation explains why the cosmos is so flat and smooth, but it also predicts the creation of a multitude of independent bubble universes.
#
“What I didn’t like about inflation was that there are very few genuine predictions – you don’t get out much more than you put in,” says Neil Turok, a physicist at the University of Edinburgh, UK, who helped develop a model for a cyclic universe, published in 2001, as a rival for inflation. “It just struck me that there has to be a better explanation.”

If the word 'Universe' is being defined as, everything; all-there-is; totality, or similar, then there is, obviously, only One Universe.

If, however, you or any one wants to say that there could be two or many universes, then you and them will just have to change the definition to, some things, instead.

And, what word would you, and them, 'now' like to use that has the definition, everything; all-there-is; totality, or similar?

#
One is that we could be a single part of a branch of infinite universes known collectively as the multiverse.

If so, then, again, how are you 'now' defining the 'universe' word here.

These universes might have appeared shortly after the big bang, they might be hiding in extra dimensions or they could pop into existence whenever a quantum property goes from a cloud of possible states to a single reality.

1. If there are 'infinite universes', then absolutely anything else 'might have' occurred also.

2. you are using the 'big bang' term and phrase here as though this is the start and beginning of this newly made up term and phrase 'multiverse'. So, where did this new 'multiverse' come from, exactly, 'God', a 'big bang', something else, or absolutely entirely nothing at all. And if it was from either of the first three, then where did they come from, exactly, or if it was the last one, then how could this even be a theoretical possibility, let alone and actual a actuality?

#
Multiverse ideas gained scientific weight in the 1980s with the invention of inflation, a period when the early universe suddenly expanded.

But, it is not the 'Universe', Itself, that is 'inflating'.


Inflation explains why the cosmos is so flat and smooth, but it also predicts the creation of a multitude of independent bubble universes.[/quote]

So, because 'inflation', itself, was invented, as you just said and claimed, then also new definitions for old words need to be invented also.

Humorous that you would write this, in the days when this was written.

1) The word "Universe" is defined as the gravitational world of stars, planets, galaxies.
In this context, there are millions of multiverses.

2) March 13, 2024. The End of the Dark Universe?
Dark matter and dark energy are terms that astrophysicists have given to two hypothetical constituents
of the universe. Neither has ever been directly observed; astrophysicists have merely indirectly inferred
their presence from their gravitational effects. They have added dark matter to explain, among other things,
why galaxies rotate faster than expected and gravitational lenses are stronger than expected.
They added dark energy to explain why the universe doesn’t just expand, but the expansion also gets
faster—no normal type of matter or energy could make that happen.
