That's not good enough. Not doubting is like saying it sounds possible. What happened to the evidence? Did it just fly out the window?
Not doubting is EXACTLY saying that it sounds possible.
Again, you fundamentally misunderstand how the scientific method works.
Science does not prove anything to be true; It either proves claims to be false, or leaves them in the "possible" basket.
If an idea has no evidence
against it being true, then it is possible.
If an idea has any evidence against it being true, then either it is wrong, or the evidence is misleading.
If an idea has been ruthlessly and frequently tested for a long time by determined people, and still has no evidence that it is false, then we can, as a shorthand, consider it to be true; But in fact it is merely possible, and can never be more certain than that - because tomorrow we may find evidence that it was, after all, false.
So, according to science, because delayed vision has been tested frequently and for a long time by determined people, real time vision is ruled out? Or does it mean that because tomorrow they may find evidence that something was, after all, false, where does this knowledge fall into according to science? Is there no point to get into this subject because it's off limits since scientists did the hard work and real time vision is ruled out? Or could his claim still be in the "possible" basket? IOW, does this author have a chance to explain his findings (as he has done; it was not an assertion) or is his claim deemed impossible, according to scientists, because they say (without understanding his explanation) that real time vision was ruled out 300 years ago, therefore his claims have been shown to be false? If that is true, then there's no point in me talking about this subject anymore. No one will even hear his explanation. Is that what you and others want? I don't want to waste my time if people are just humoring me.
One does not use evidence to test for truth; One uses evidence to test for falsehood. It is impossible to prove things true, outside of mathematics.
Science is the process of pruning the false ideas from the tree of possibility, so that what remains is more and more possible.
I understand. You explained this very well. Thanks bilby.
OK, well there's another thing we can do to test for falsity; We can use logic.
It cannot tell us which ideas are false, but it can tell us that one of any two must be.
We can look at "possible" idea A, and use logic to show that if A is true, B must be false, and vice-versa. Note that it is only possible to show that things are false; Just because two ideas cannot logically both be right, that doesn't imply that they can't both be wrong.
It's like looking for your friend's pet. He might be in the loungeroom; He might be in the bedroom. Logically, he cannot be in both. But he could be in neither.
Now, that doesn't tell is which is false, so it's not very helpful; But if there's another idea, C, which has the same logical relationship with A, then we can start to get an idea of which way to bet - we want to assign ideas to that "false" category, the help to prune the tree of "possible".
If our idea is that maybe your friend has a cat in her bedroom, then finding her pet in the loungeroom would falsify that idea; As would finding her dog in her bedroom (after we have already established that she has only one animal).
So, if A implies that B is false, and C (which has nothing to do with A - which room a pet is in tells us nothing about whether it is a dog or a cat) implies also that B is false, we would be more likely to be right if we bet that B is the false claim out of these three.
If A and C are both very well tested, and we have put huge effort over long periods of time by our best and brightest into trying to falsify them, and have failed to do so; And if B is a new idea that has yet to be thorougly tested, it is an even better bet that B is the idea that will turn out to be false.
Now, if not only A, and the independent idea C are logically incompatible with B, but so is D, which is yet another unrelated and well tested "possible", it starts to look a bit foolish to bet on B.
And if E through Z (all independent of each other)
also all contradicted B, one would be a total fool to bet on B being right, and all the rest of the alphabet being wrong - even though we have not yet been able to falsify any of the alphabet.
Of course, long shots do occasionally pay off, and it is possible that the vast majority of what we think we know is, in fact, wrong.
But that's not the smart bet. Particularly when the idea B, that is the challenger for that huge body of well-tested ideas, has not itself been very well tested.
