(by the way, what's wrong with the idea that the bomb doesn't ignite the sun, but simply serves as a detonator?)
In theory, there can be no hypotheses that contradict the theory itself, which has a clear answer to the movement of objects at the speed of light. "In Einstein's theory, no information can propagate faster than the speed of light in a vacuum." - Wikipedia, many consider it not a very authoritative source, but this point of view coincides with the generally accepted one; perhaps you can provide a link to a more authoritative source?
The most obvious example is a wormhole, plus it's interesting if its exits move relative to each other. There are also theories similar to a warp bubble around an object, relative to which time and space are distorted, but all of them, like the wormhole, come 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 topic is undoubtedly very interesting. Those who are interested can learn about modern theories.
Well, this is not relevant to us, road engineers.
