To be more specific: Do you have a degree in the university? In which field? Is it related to what you want to publish?
In which field yo want to publish? In physics they like papers in journals. In computer science, they like conference presentations.
Beware that there are many predatory journals that publish any article if you pay the fee. Nobody cares about them, it's borderline a scam.
From the other comment:
> Proofs and working systems are good, criticisms of common methodologies are bad.
I agree. Be very clear about what is your new result. It is very difficult to convince people about something like "Quantum Mechanics is wrong" unless you have a big trajectory or a very solid proof. It is easier if you have a new algorithm that outperforms the 2 or 3 more popular algorithms in the 2 or 3 more popular benchmarks.
