It is a theory, meaning even scientist agent 100% sure it's correct, but it's the best one we currently have. With the new data coming in from the jwst (James Webb Space Telescope) it's looking like we might need to reconsider it though

That is not what "theory" means in science. Science does not deal with 100% correctness in any circumstance, so there's no need for a separate word to describe that. "Theory" in this context roughly means "model". For example, the "theory of gravity" doesn't mean "we're not sure that gravity is real", it means "here's our model for how gravity works".

JWST is not producing anything that would dispute the basic premise of the Big Bang model - the idea that everything was hot and dense. It is fine-tuning various details of it.

Well there are some scientist fron what ive read disagreeing with that so...

I'm a scientist, and I'm saying that you are made of wonder bread so.....

Some scientists can say anything and have zero effect on science.

Source? I’ll genuinely consider any legitimate source you provide, but without a source to consider I’m going to presume, as a scientist, that it’s just nut jobs trying to make noise for attention. From every bit of scientific evidence that I, a scientist, have seen, there’s nothing from the James Webb scope that disputes the Big Bang.

Ive seen articles from my feed saying that there is more doubt than before, I def am not making it up or claiming that ive come to this decision based on info from it, just regurgitating what ive read.

Also agree with u it more than likely is just click bait so guess I shouldn't have said anything. Hate the downvotes just for saying something I read, not wrote

Can you elaborate on this? What are we learning from the JWST that would be contrary to Big Bang?

Im no scientist, and this is the first article I found doing a quick search but have seen others. What I remember reading elsewhere is its seeing galaxies too old to line up with the big bang timeline. At least in its current model. And of course there is debate over any new idea so we'll see what comes of it

I think you are reading a very over hyping article. Read the research behind it. It's very interesting things, but they're arguing about minute details in the timeline of the big bang. Not really suggesting the big bang didn't happen.

The JWST results so far have not contradicted the Big Bang Theory. That article is contributing to misinformation and fear mongering, tbh. As Dr. Becky’s video (that u/wanderlustcub shared) explains, cosmologists are actually excited to see if JWST proposals will help constrain the “crisis in cosmology” which is basically the Hubble constant, or rate of expansion of the universe.

Exactly this.

My understanding was always that the Big Bang itself was the problem. That the specific features observed during the Big Bang don't match up with what they should be given what we know about physics. It's just a "we look in our telescopes and see this happen, we don't really know why".

So any new irregularities that JWST can find would likely be super helpful in figuring out why the Big Bang behaved the way it did, and could potentially lead to new physics as a result.

Right! It’s actually not that the Big Bang theory is the problem itself - it’s the best framework we have so far that makes sense of all the observations (e.g. the expanding universe, the cosmic microwave background radiation, etc). The features that you’re referring to are dark energy and dark matter. We still don’t understand what those really are, and if we want to understand our entire universe and its expansion we need to get a handle on those two. And that’s where JWST will hopefully come in. I’m excited to see what we find out!
