Too much politically “settled science” based on unsubstantiated and unquestioned assumptions blocks alternative explanations.

Observations contradict galaxy size and surface brightness predictions that are based on the expanding universe hypothesis
Eric J Lerner

https://academic.oup.com/mnras/advance-article-abstract/doi/10.1093/mnras/sty728/4951333?redirectedFrom=PDF

“An overall comparison of cosmological models requires examining all available data-sets, but for this data-set there is a clear contradiction of predictions based on an expanding universe hypothesis.”

I think they got these in the wrong order. The evidence is based on extrapolation and progressive logic.
  1. It's expanding.
    • Therefore it follows that it was once smaller in the past
  2. It’s cooling.
    • Things that expand also cool. So if follows that the universe was once hot as well as small.
  3. It’s dark.
    • This is actually somewhat false. It's glowing in microwaves instead of blinding white light because it's cooled to the point we can't see it. But it's also a subtle point that the universe is not infinite in age, like other theories suggest.
  4. It’s three-fourths hydrogen.
    • It matches mathematical models of what early nucleosysnthesis would have produced in a small, hot universe. The models are not based on observation, but extrapolation, if you go back far enough to when the universe must have been, say, the size of a peach.
  5. It used to be different.
    • This just suggests that the universe has a finite age, therefore a beginning (namely the Big Bang)

Problem: gravity bends time; and time is not a constant....After the “big bang” mass flowed out into space faster than the speed of light — which is theoretically impossible; unless, that is, time itself was compressed.

Space/Time itself doesn't need obey the laws of relativity. Space expansion can and actually does proceed at a rate faster than light. According to the Inflationary Big Bang model, the very early universe expanded at a rate many times faster than light. Then it soon after slowed down. Then, some time later, it began to accelerate again. However, this second burst of acceleration was much much slower than that of the inflationary period. In addition, there are supposedly galaxies outside the "observable universe" being carried away from us at speeds faster than light. The further a galaxy is, the faster it recedes, due to universal expansion. And remote galaxies can and do apparently recede at rates greater than light.

Big bang, big shmang. The theory doesn’t explain everything, especially where the fuzzy peach came from!

Exactly what I was thinking? Where was this peach to begin with?-)

Cosmic Inflation: How It Gave the Universe the Ultimate Kickstart

Cosmic Inflation: How It Gave the Universe the Ultimate Kickstart (Infographic)

Inflation is the mysterious force that blew up the scale of the infant universe from sub-microscopic to gargantuan in a fraction of a second.
Credit: By Karl Tate, Infographics Artist

In 1980, to explain the conditions observed in the universe, astrophysicist Alan Guth proposed cosmic inflation. The term inflation refers to the explosively rapid expansion of space-time that occurred a tiny fraction of a second after the Big Bang. In another tiny fraction of a second, inflation slowed to a more leisurely expansion that continues to this day and is accelerating.

Major Discovery: 'Smoking Gun' for Universe's Incredible Big Bang Expansion Found

The earliest radiation astronomers can detect is called the Cosmic Microwave Background, or CMB. This is radiation that was released about 380,000 years after the Big Bang.

And all of this was suggested by a Jewish rabbi, Nachmanides, about 900 years ago based on his study of the Bible.

So, as our universe expands it is colliding with other universes?

The universe used to be the size of a peach and a trillion degrees? How do we know this?

Well, if the universe did begin as a singularity, a region of space many times tinier than a single atom, I suppose it had to grow to the size of a peach somewhere along the way.

Lemmings also decide that stampeding over a cliff is the thing to do by multiple small decision all pointing the same way...

To Lemmings, suicide is settled science.

Inflation (cosmology)

Around 1930, Edwin Hubble discovered that light from remote galaxies was redshifted; the more remote, the more shifted. This was quickly interpreted as meaning galaxies were receding from earth.

If earth is not in some special, privileged, central position in the universe, then it would mean all galaxies are moving apart, and the further away, the faster they are moving away. It is now understood that the universe is expanding, carrying the galaxies with it, and causing this observation.

Many other observations agree, and also lead to the same conclusion. However, for many years it was not clear why or how the universe might be expanding, or what it might signify.

Based on a huge amount of experimental observation and theoretical work, it is now believed that the reason for the observation is that space itself is expanding, and that it expanded very rapidly within the first fraction of a second after the Big Bang.

This kind of expansion is known as a “metric” expansion. In the terminology of mathematics and physics, a “metric” is a measure of distance that satisfies a specific list of properties, and the term implies that the sense of distance within the universe is itself changing, although at this time it is far too small an effect to see on less than an intergalactic scale.

The modern explanation for the metric expansion of space was proposed by physicist Alan Guth in 1979, while investigating the problem of why no magnetic monopoles are seen today. He found that if the universe contained a field in a positive-energy false vacuum state, then according to general relativity it would generate an exponential expansion of space.

It was very quickly realized that such an expansion would resolve many other long-standing problems. These problems arise from the observation that to look like it does today, the Universe would have to have started from very finely tuned, or “special” initial conditions at the Big Bang. Inflation theory largely resolves these problems as well, thus making a universe like ours much more likely in the context of Big Bang theory.

No physical field has yet been discovered that is responsible for this inflation. However such a field would be scalar and the first scalar field proven to exist was only discovered in 2012 - 2013 and is still being researched. So it is not seen as problematic that a field responsible for cosmic inflation and the metric expansion of space has not yet been discovered.

The proposed field and its quanta (the subatomic particles related to it) have been named the inflaton. If this field did not exist, scientists would have to propose a different explanation for all the observations that strongly suggest a metric expansion of space has occurred, and is still occurring (much more slowly) today.

If our universe was the size of a peach, what surrounded it?

Your question is not meaningful. You're thinking in 3, maybe 4 (space+time) dimensions.

It's like asksing, "Who made God?" That's another question that assumes 4 dimensions.

Both theories take faith.

But scientist don't believe in “faith.”

The theory doesn’t explain everything, espcially where the fuzzy peach came from!

Georgia!
