Is there something secret about salamanders?

No, just a lack of understanding...

I can't be the first one to figure it out, if Michael Levin has done it it is probably there since the 1970s. Well but I am gonna keep it to myself for my own benefit, so that I hopefully do not come across a no answer @@

Salamander was not born on that day, that rules out the regeneration capabilities. And I think that was not earth bound, aka, not someone time traveled from the future. The interesting part is it was shut down by lightning though and the weather storm device is clearly not on my side.

It is not sci-fi  and/or  pop science  and/or  juvenile science . .. . None . . .. It  IS  feasible . .  .. . Problem is that here on this forum , very unfortunately , there are many who are here to spend time just scoffing at AND picking on newcomers like Fredreload . . .. . . I am almost sure that even this plain constructive criticism will receive lots of scoffing and negatives and so on and so forth . . .

One of the truly beautiful things about science is we don't have to bother with sentiments like this. It's easy enough to see, after 8 PAGES of "picking on newcomers" (what irony), that the idea as presented is NOT feasible. It's been explained over and over again EXACTLY where fredreload is mistaken. How you could view that as anything but scientific professionalism and rigor baffles me. It's science, not a popularity contest.

Are we supposed to encourage him to pursue a path we know will fail? How cruel of you!

I did not say that. You are distorting even a non-partial onlooker , too . .  .

Closing on 1000 posts and 5 years here; that’s hardly a newcomer. And there’s plenty of quality science given in response to dubious claims. The main issue is that the feedback wasn’t incorporated into the discussion.

I appreciate your hard work on directing members to the best path of argument all these years with all your posts , Dear Sir . .... .

I am quite unwilling , however , to take my words back....

Why surmise? Why not review the 8 pages of evidence? This is a science discussion forum.

I didn't claim you "said" it, I asked if you meant to encourage fredreload down a path known to be bad. Why else would you be claiming his idea is feasible, and that the members are picking on him? I don't understand your argument with our attempts to falsify an idea, and I'm asking for clarity.

Dear Moderator !

The reason why I wrote that statement is that "Interlocutors" almost totally disbelieved the feasibility of such a object of speculation.

Now , to return back to the topic itself , I am to make mention of the fact that any conglomeration of matter , especially in the condensed format , AND : under next-to-zero-Kelvin conditions , possesses the capacity to slow down photons that are moving in its own manifold. Outside of  the said manifold , light has the velocity with which to stunt contravariant tangent fields ( of tensors).And , as a result , to keep original velocity. . . . .  . .

Wow. That's quite a bunch of physical concepts completely wrongly understood. Let's leave aside the fact that "contravariant tangent fields" doesn't mean anything. Photons are never "slowed down", and light doesn't need any specific action on it in order to keep its original velocity. Light moves at fixed, universal speed $$2.998\times10^{-8}\textrm{m}\textrm{s}^{-1}$$, not as a consequence of being "stunt", but of space-time symmetries.

I'll repeat that last bit, as it didn't come out right. I meant:

$$2.998\times10^{8}\textrm{m}\textrm{s}^{-1}$$

There is a well respected science fiction story about this by Bob Shaw, based on writings of Thomas Moore.

contravariant tangent fields does mean something , Sir . . .

## Contravariant transformation

The components of a (tangent) vector transform in a different way, called contravariant transformation. Consider a tangent vector v and call its components v i {\displaystyle v^{i}} on a basis e i {\displaystyle \mathbf {e} _{i}} . On another basis e i ′ {\displaystyle \mathbf {e} '_{i}} we call the components v ′ i {\displaystyle {v'}^{i}} , so

v = v i e i = v ′ i e i ′ {\displaystyle \mathbf {v} =v^{i}\mathbf {e} _{i}={v'}^{i}\mathbf {e} '_{i}}

Fields are neither covariant, nor contravariant. Covariant or contravariant character apply only to coordinates. The need for that distinction comes from having two bases, mutually dual $$\left(\boldsymbol{e}^{i},\boldsymbol{e}_{j}\right)=\delta^i_{j}$$, whenever that distinction has to be made. Certainly not here.

I didn't say light speed is constant. I said photons don't slow down. It's different.

Fields (vector fields, tensor fields...) are neither covariant, nor contravariant. Covariant or contravariant character apply only to coordinates. The need for that distinction comes from having two bases, mutually dual $$\left(\boldsymbol{e}^{i},\boldsymbol{e}_{j}\right)=\delta^i_{j}$$, whenever that distinction has to be made.

Ah !  I see you are closer to catching  the idea , Sir . . . . . .
