People in the EU don’t like the term infinite.
Can we just say without beginning or end? Ageless?

Hmmm -- without beginning or end dimension wize -- ok (ie infinite)(ie infinite up n down n across)(ie in 3 dimensions).
And without beginning or end time wize -- ok (ie eternal)(eternal going back in time & eternal going forward in time).

One problem is that BBers might agree re infinite dimension wize -- koz i think that according to some BB theory if u travel in what u think is a straight line then u come back to where u started.

And another problem is that many of us don believe that there is such a thing as time -- time is an illusion (me)(Einstein)(others) -- hence the concept of eternal might be problematic.

Ageless. Hmmmm -- no, i dont agree -- i think that everything has an age, even if only an instant -- i think that ageless is a term used praps by theater critics etc not science.

No, the Big Bang theory is not 'broken.' Here's how we know.

We don't? Says who? ;p
It all depends on the context. ;]

ASTRONOMERS MAY BE ON THE CUSP OF A “POTENTIALLY REVOLUTIONARY” COSMOLOGICAL BREAKTHROUGH

These astronomers have the next 50 years all planned out.

When the first images from the James Webb Space Telescope were released last July, astronomers got their earliest look at cosmic history yet, seeing captured images of what the universe looks like billions of light years away. They expected to maybe see some "tiny, young, baby galaxies." What they found, however, was something far greater – six massive galaxies dating back about 13.1 billion years that appeared to be just as old as the Milky Way is now.

"These objects are way more massive than anyone expected," astronomer Joel Leja said. "...We've discovered galaxies as mature as our own in what was previously understood to be the dawn of the universe." 

Those findings were published on Wednesday in the journal Nature (https://www.nature.com/articles/s41586- ... MSF0951a18). 

Ivo Labbé, the lead author of the study, said they started realizing they were onto something barely a week after the telescope images were released. 

"Little did I know that among the pictures is a small red dot that will shake up our understanding of how the first galaxies formed after the Big Bang," Labbé said. "...I run the analysis software on the little pinprick and it spits out two numbers: distance 13.1 billion light years, mass 100 billion stars, and I nearly spit out my coffee. We just discovered the impossible. Impossibly early, impossibly massive galaxies." 

… snip …

That red dot was just the beginning. The next day, they found five more apparent galaxies. And the pictures taken by JWST show them as they were when our 13.8 billion-year-old universe was a mere 700 million years old. And if that's the case, they said, that would mean that the galaxies formed "as many stars as our present-day Milky Way. In record time." 

… snip …

"Regardless, the amount of mass we discovered means that the known mass in stars at this period of our universe is up to 100 times greater than we had previously thought," Leja said. "...The revelation that massive galaxy formation began extremely early in the history of the universe upends what many of us had thought was settled science. We've been informally calling these objects 'universe breakers' — and they have been living up to their name so far."

The objects, they said, are so big that scientists may have to alter cosmology models or force a total consensus revision of the belief that galaxies start out as little dust clouds and take a long time to become giant entities.

… snip …

The scientists explained that they should not exist under current cosmological theory, because there shouldn't have been enough matter at the time for the galaxies to form as many stars as ours has.
