Tired Light, Variable Speed of Light, and Steady State are all theories that I personally believe got thrown out too quickly. Some because YEC hijacked them to try to justify a 6 thousand year old Earth, making it career suicide to investigate as a serious researcher.

James Webb is hopefully going to make big changes. I find it notable that very few of its observations are being published soon after they are made. They are finding fully formed galaxies way too early, and having a hard time explaining it (dark matter is always there to rescue the BBT though).

I'm scientific and swear by the scientific method. I don't think the Big Bang Theory is the only conclusion to be made from the evidence, though.

There is a lot of terrific evidence behind it. The one point I question is why we conclude that metric space has expanded, yet the matter in it hasn't.

In 2021, there was the first mainstream physics journal article that argued that Cosmic Coupling is a thing. The researchers showed that there's a good chance a certain black hole could only have gotten so large if it's mass increased proportionately to the expansion of space.

So then if mass expands to, you don't necessarily iterate back to a single incredibly dense Big Bang precursor. The universe has simply always had its current proportions, but on an increasingly larger absolute scale throughout time. The only hint that this would have happened would be in the redshift of light that left objects when then were smaller and with less energy.

It's one possibility.
