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.

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.

Your sentence is absolutely right. 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. . . . . . .

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. Just now, joigus said: Wow.

Quote Wikipedia https://en.wikipedia.org/wiki/Covariant_transformation 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}} in which
