As I explained several times, scientific theories are like crimes. How do you solve a crime? You can't go back in time and if it's not recorded, how can you make sure who did it? Well, you look at the evidence and when you find the DNA of the killer on the scene and the victim, the weapon in his house with his fingerprints, his motive, witnesses that saw him at the time of the crime around the area of the crime, etc, you can be pretty sure he did it but are you 100% totally sure? Never but it's more than enough to go to jail, same thing with scientific theories.
But that isn't the point.
The point revolves around the science that scientists want to accept. People like the clear way Einstein stated Relativity. So they ignore aether theory, micro gravitation theory, electric universe theory, and a whole lot of theories that might even be better at explaining things than Relativity. It's a personal preference. And for those who aren't studied in, say, Relativity, they simply get on board because of the popularity of a scientist who pushes a popular theory. The theory, itself, might be worse than a whole bunch of other theories, or some science that is not even a theory, but the choice is made for reasons other than the science involved.
Take Dawkins and evolution. Dawkins might be a bit of an evolution scientist. But he is mostly a popular mouth that says all kinds of things he can't scientifically back up. And he even admits this in his books.
Many forensic cases are being overturned because forensic science isn't accurate AND because it wasn't really followed anyway. Yet there was a guilty verdict because the jury trusted the forensic people.
The only reason a person goes to prison for a crime like you explained above is, he doesn't have enough sense to stand up for his rights. So, he volunteered for prison. Almost never will circumstantial evidence convict a person who firmly demands his rights: witness and conclusive evidence. OJ Simpson is an example of this.
Do they ignore it? They don't ignore it, Einstein himself talked about Aether, for example, newton too, they simply couldn't really prove it, right now there are scientists still working on it : https://en.wikipedia.org/wiki/Einstein_aether_theory but it just doesn't have enough evidence behind it to be the accepted theory, it's not because scientists ''ignore it'' lol.
''In physics, aether theories (also known as ether theories) propose the existence of a medium, a space-filling substance or field, thought to be necessary as a transmission medium for the propagation of electromagnetic or gravitational forces. Since the development of special relativity, theories using a substantial aether fell out of use in modern physics, and are now joined by more abstract models''
