Is there a current list of the major problems or conflicts with the standard cosmology models?

Only if you completely ignore the expansion of the universe.Peter Watkins said:Here's one. The Hubble space telescope can see 12 billion light years of distance in most directions, more in some directions. This can only mean that 12 billion years ago the, (visible to us), universe had a diameter of at least 24 billion light years. And yet it is said to be "only" 13.7 billion years old. Something of a paradox there!

Ok then: please explain what the paradox is that you see. Because I see no paradox in those two pieces of information. They do not contradict each other.Peter Watkins said:This answer,above, makes no sense. It admits of no reply.
No, it's a problem with your understanding of cosmology. What exactly do you mean by "The further back in time we look, the larger it can be seen to have been." What specific cosmological observation are you referring to here? To calculate the distance to the edge of the observable universe (the particle horizon, [itex]d_H[/itex]), one must compute the integralPeter Watkins said:If the universe is expanding then to look back in time, via distance, would be to see a smaller universe. But we don't! The further back in time we look, the larger it can be seen to have been. To expand to a diameter of at least 24 B.L.Ys. in only 1.7 B.Ys. would seem to me to be a problem with our picture of the universe and its evolution.

Cosmology is the scientific study of the origin, evolution, and structure of the universe. It is important because it helps us understand the fundamental laws and principles that govern the universe, as well as our place and role in it.
Standard models in cosmology refer to the widely accepted theories and models that attempt to explain the origin and evolution of the universe, such as the Big Bang Theory and the Inflationary Model. There are conflicts with these models because new observations and data have challenged some of their assumptions and predictions, leading to the need for further exploration and potential revisions.
Some common problems in cosmology that scientists are currently exploring include the nature of dark matter and dark energy, the expansion rate and shape of the universe, and the origin of cosmic structures such as galaxies and clusters.
Scientists investigate and address conflicts with standard models in cosmology through various methods, such as collecting and analyzing new data from telescopes and experiments, developing new theories and models, and conducting simulations and experiments to test these theories.
If conflicts with standard models in cosmology are resolved, it could lead to a better understanding of the universe and its evolution, as well as potential advancements in fields such as physics and astronomy. It could also open up new avenues for scientific research and discovery. However, it is also important to remember that conflicts and debates in science are a natural and necessary part of the scientific process, and may not necessarily lead to a complete overhaul of existing theories and models.
