Problem with the Big Bang theory is, inability for explaining the perfect position, and workings of the matter, space and time in the Solar system — Corvus

The James Webb telescope findings might be saying you are correct. BB needs correcting but the details themselves don't matter much to philosophy

. If the BB had created the solar system as it is now, then it must be the most unbelievable magic ever created in the universe nothing short of the miracle act of some omnipotent being. But is it — Corvus

Reality itself could be the miracle, God itself could be the miracle.

Problem with the Big Bang theory is, inability for explaining the perfect position, and workings of the matter, space and time in the Solar system. — Corvus

That’s not a problem with it. The workings are pretty much standard for something with no design or intelligence.

It would have been more like total chaos with debris of the rocks, minerals and burnt out matters scattered and floating around in the space even at this time. You see some of the old gignatic stars exploding when they are dying. It is nothing short of the massive nuclear explosion destroying and burning everything around them. — Corvus

Tell me you don’t understand the theory without telling me you don’t understand it.

So space and time are not separate? And motions come from them? I've speculated on this forum that motion creates time as it moves through space so there is no need for a before the Big Bang being it's creater (motion) moves singularly at the moment of the universe's and time's first motion forward. It seems like something coming from nothing but it's not. The primordial singularity is it's own casuality — Gregory

Your speculations mean nothing at all. Space and time aren’t separate, they exist in tandem. Motion doesn’t come from them; it just happens if things exist.

There is no primordial singularity, the universe has always existed.

One of these is false:

1. Particles cannot influence one another faster than the speed of light (locality)
2. Particles have well defined properties before being measured (realism)

As examples, the Copenhagen and Many Worlds interpretations reject realism, and the de Broglie–Bohm theory rejects locality. — Michael

I only skimmed the first page of replies, and this seems to be the only answer that succinctly answers the question.

I studied physics at university, but only ever really felt fully comfortable with classical physics. I got the top score in the class on the last quantum mechanics test I took, but it just felt so weird and I never really felt like I mastered it (I never worked past a bachelor's degree).

My understanding of some of the weirdness in quantum mechanics is that quantum particles do not appear to have defined momentum or position prior to being measured. This is not a limitation of our measurements, but a property of the particles themselves.

So, when I hear, "anti-realism", I think of some kind of interpretation like the particle has no real defined traits until observed by a consciousness(or possibly, until interacting with any macroscopic object). At the macroscopic scale, things only appear to be determined because the average behavior of a huge number of random objects is fairly well determined.

I don't really have a dog in the fight, because as I said, I don't feel like an expert. The only thing I can think of is that maybe position and momentum aren't really the fundamental building blocks of existence, but maybe the wave function itself (which describes a probability distribution of position or momentum) is the true existence of the particle. As I understand it, the wave function ought to be well defined at all times.

I have had a similar thought about relativity. It seems so bizarre to me that lengths and mass change due to velocity, and that velocities cannot be added by simple arithmetic (if you throw a ball with V1 on a train at V2, the final velocity is NOT V1 + V2 according to relativity). I would think that if a thing were truly "real", then it would be observed to be the same for all observers. It made me wonder if things like mass, and position are not truly the fundamental building blocks of existence, but are only derived phenomena from something even more fundamental. I couldn't begin to tell you what that is though.

I'm pretty sure physics doesn't really have anything to say about realism, anti-realism, or idealism, but that hasn't stopped folks from trying. — Darkneos

You're right, it's not about the *philosophical* concept of realism, it's a physics concept.

In short, what quantum mechanical experiments, especially Bell's Test, give extremely strong evidence for, is that a classical physics type view of reality is incorrect. That's what "local realism" means.

In classical physics, for any given proerty you could measure, every object in existence has distinct values for that property - all the time, whether you're measuring it or not. Momentum, location, rotational velocity - everything has a distinct value for all measureable properties.

That's local realism, and *that* is what's not true, at least for the things we are generally inclined to think of as 'objects' at the fundamental level ie protons neutrons electrons.

Bell's Theorem demonstrates that you have to give up on at least one of locality or realism. In either words, either you have to choose to believe that causality can be non-local, faster than light, and contradict special relativity, OR you have to believe that measurable properties don't have singular distinct values when not being measured. Or both.

There is a third option, but... we don't talk about the third option.

As examples, the Copenhagen and Many Worlds interpretations reject realism — Michael

I think the Copenhagen interpretation also rejects locality, no?

-edit, i guess i've always misinterpreted what the copenhagen interpretation is.

Would you elaborate, please?

Tell me you don’t understand the theory without telling me you don’t understand it. — Darkneos

What do you not understand on my understanding of the BB?

Without solid explanation backed by evidence and reasoning, the BB is not much different from the creation of the world story in the Genesis of the Old Testament in terms of its coherence and cogency.

If you accept the BB blindly, you have committed yourself to being an esoteric shaman under the apparel of science.
