Friends, allow me to give you (with a drawing) a simple summary of my cosmic and atomic model regarding the deformation of the gravitational and magnetic fields around the large nuclei of matter (in density).
As can be observed and can be deduced, there is no such deformation of Einstein's space-time, and even less so in the shape of a funnel.
What are deformed are both magnetic and gravitational lines of force.
This is deduced with many assumptions and conclusions, such as that accelerations are produced when lines of force (f=m.a) are applied to the bodies that are attracted; that they do not slow down when taking the curve, but rather accelerate when approaching the core, etc.
On the other hand, and already with the powerful telescopes, Hubble, Web, it has been clearly verified that those tube-funnel deformations (black holes, wormholes, etc.) that Einstein's theory proposes do not exist.
However, and since the laborious and boring way of investigating with hard work and few discoveries (as scientific research always was), has been abandoned and now it is simply replaced by science fiction imagination and inventiveness, as this leads us to ignore and deny what Our eyes see and our telescopes observe, and continuing to believe is an imaginary world, but very gratifying because we can invent what we like best without having to abide by any scientific logic: Let's imagine mysterious worlds, space-time holes that take us to other universes , etc.
What need do we have of that boring cosmic reality!

Another relativistic misconception:

"The speed of light is different relative to any other reference frame distint from own"
With the test of the neutrino, or any other particle, we can check how the speed of light (whether considered a moving particle or wave) is different for each frame of reference.
