Thanks for this. We will have to wait for the final verdict. Albert Einstein is still resting peacefully!
I have no comment about the experiment with the neutrinos but all of you are misapplying Albert Einstein’s laws. The law’s say an existing object with a rest mass traveling at a speed less than the speed of light could not be accelerated to the speed of light because it would accrue an infinite mass. But matter can be created directly out of energy. There is no rule from Albert Einstein’s law’s that says that a particle could not be created with an intrinsic velocity greater than the speed of light and the mathematics also allows for a completely separate universe to exist where the slowest particles of matter would have the greatest energy and the speed limit would be equally unreachable but the speed of light would the lower limit. No such particles have even been detected but they have a name Tachyons.
Since neutrinos have been determined to have a small rest mass it was unlikely that they could move faster than the speed of light. But if there was a particle with a low enough rest mass, by the rules of Quantum mechanics and the uncertainty principal it is not unconceivable that such a particle could at times have an effective zero rest mass by uncertainty and at other times have a very tiny mass. I am not saying that such a particle exists only that our current understands does not yet forbid it. The problem with our current laws is not that their predictions have proved false. It is all of the aspects of reality that they do not predict. So we know that at least that they are incomplete.

I am afraid that you are misinterpreting Albert Einstein’s Laws, Quantum Mechanics, and the Uncertainty Principle.
The Uncertainty Principle is about the limits of measurement. It does not mean that a particle has variable mass, or can have a mass less than zero.
The equations of Quantum Mechanics do allow solutions for particles that travel faster than the speed of light, however:
Such particles must have an odd number of imaginary dimensions. What imaginary dimensions means is, well nobody knows. However, Quantum Mechanics makes it is very clear that these particles would be totally incapable of interacting with our space-time.
Current theory allows for the construction of continuums where faster-than-light particles exist, however in such continuums the speed-of-light becomes a minimum velocity that nothing can go slower than.
These particles are called Tachyons. Science does not say that Tachyons do not exist, but Quantum Mechanics does say whether or not they do exist cannot be detected according to current theory so not test can be constructed to falsify the theory. Therefore the existence or non-existence of Tachyon is irrelevant and can be ignored.
Albert Einstein’s Laws state that mass and energy are equivalent. Mass is not created from energy, energy is converted to mass. Matter is mass with momentum, which requires kinetic energy, which is part of the energy price of the conversion.
Not sure what you mean by “It is all of the aspects of reality that they do not predict.”, but just because you want something to be true does not mean that it must be true.

I am not sure how we turned the thread into a physics board but there is still a lot we do not know about how the universe really works. But as a point of logic we must always remember that our mathematics we hold so dear, perhaps too dear, as well as the laws we have ascribed to nature are completely human inventions and nature is not bound or limited by our inventions. Some of these human inventions “mathematical systems bases upon axioms (Axiomatic systems of logic)” can be used to model, to some degree of accuracy, real phenomena within the universe that we can observe producing reliable results we can profitably exploit. All models created by human beings are simplifications of real events that leave out some real physical features to simplify the description of state so as to predict events, as such they are always approximations. Within my lifetime I have seen so many scientific dogmas that were questionable then overturned and discredited. I find it hard beehive that the process has now come to a complete halt.
I think you are misrepresenting Quantum Mechanics and the Uncertainty Principle. Though there is more than one view on the subject within the literature I will grant you, the subject is not resolved to everyone’s satisfaction. My own view, which I hold with many others, is that everything is quantified mass, energy, and space, which when acting together create the since of time. This view better explains phenomena like election tunneling and both supper conduction of current and frictionless fluid flow far better than the measurement explanation of the Uncertainty Principle. Though I agree that these are effects seen within populations of individual partials that never-the-less are interacting with each other and not a single measurable events seen in the classical context.
I consider the question that some form of matter could behave is ways not predicted by Albert Einstein’s Laws still to be open because there are things we know to exist that nether Albert Einstein’s Law’s nor Quantum Mechanics predicts.
Some think that a complete understanding of natural phenomena may be beyond the current ability of human beings to understand. I side with the group that that goal is within out capacity but we are not there yet. As to what is it that I do want as you put it? I just want to know as much about how the universe really works as I can. But part of that knowledge is knowing what I don't yet know for sure.
Hypersonic missiles will match and even exceed the velocity of a railgun round. Its only to be expected that most railgun rounds would have to have some onboard guidance so they won't be as cheap as expected.
One video on the web mentions the potential of the railgun for air defense.. a railgun round that can release a swarm of metal buckshot in the path of an incoming missile..

Correct
The big difference is that the missile will be 20x to 50x the size of the projectile. Of course the railgun itself and the associated equipment are much larger than a simple VLS, but it all comes down to the number of rounds carried.
Up to several dozen the missiles are more compact, probably somewhere between 30 and 80. Above that the railgun takes less space and weight. They are proposing to have several hundred rounds in the magazine.

And that is saying a lot. Having the ability to engage, and to keep engaging, is a tremendous advantage and is one reason why deck guns are still a viable weapon. Low cost per round is another. Making this an unguided weapon means it is impossible to defend against. A rock, traveling at hyper velocity, will continue on regardless of countermeasure. You will not spoof it, decoy it, frustrate it, or blind it . . . unless as said above, someone puts a seeker on it. Not sure why it would be needed unless it is to be used to intercept other missiles. A ship isn't going to be able to move fast enough to avoid these rounds for very long.
