It's easier to call the director of the sun and tell him to have the gnomes in the solar boiler room add more coal.

Perhaps they didn't know the phone number and decided to add something more effective than coal themselves. In general, read one of my previous posts about assumptions in science fiction films.

But what does it matter who has the more authoritative source? If Einstein said, "It's like this, and it can't be any other way," should we simply take his words as an axiom?

However, modern science adheres to his old theory, doesn't it? And he didn't just "say" it; he scientifically substantiated his theory.

Science is constantly evolving, and so are our views. Now, for example, many scientific theories about faster-than-light speed have been developed, which the old Einstein didn't even know about.
The most obvious example is the wormhole, plus it's interesting if its exits move relative to each other. There are also theories similar to the warp bubble around an object, relative to which time and space are distorted, but all of them, like the wormhole, boil down to creating a space with negative energy density, the so-called "exotic matter." In fact, an example of such exotic matter has been found: the Casimir vacuum - an ideal vacuum in which a pair of virtual particles (e.g., a proton and an antiproton) is formed every moment and instantly annihilated, i.e., (+1) + (-1) = 0. This is absolute zero. As far as I know, successful experiments have been carried out on very small scales to create such an environment.
The subject is undoubtedly very interesting. Those who are interested can learn about modern theories.

Well, I can also come up with some hypothesis, say, about Big Flying Non-Material Pink Elephants, and try to prove that they don't exist. And by the way, one should distinguish between the concept of "Theory," which is scientifically substantiated, and the concept of "Hypothesis," which is nothing more than an assumption. All these hypotheses about faster-than-light speeds and wormholes fall into the latter category. In science, there would be an incredible uproar if someone could substantiate these hypotheses and refute the theory of relativity. And in all these hypotheses, non-material "virtual" objects appear that do not have any energy or rest mass, and the topic of our dispute, I remind you, is "science fiction," and in it, faster-than-light movement of an entire spaceship with a crew often occurs, which, to put it mildly, does not resemble a photon in its properties. That is, they are showing nonsense! But without this assumption, an entire layer of science fiction about the exploration of outer space would have to be discarded.
