Which film has the most realistic physics

From the beginning, the American television series Star Trek thrilled its fans not only with the exciting experiences of the spaceship crews under Captain Kirk, Picard & Co., but also with the precise description of physical aspects and future technology. Captain Kirk didn't just “accelerate” when the Enterprise set out on one of her many voyages, but ordered the spaceship to accelerate to “warp speed”. The name of the warp drive required for this immediately sparked speculation about the drive mechanism - like so many other amazing inventions on board the Enterprise such as beaming or the replicator. The questions always arise: “How does it work?” Or “How could it work?” When the series speaks of “neutrinos” or “antimatter”, we are dealing with terms that are not only used by today's physicists are very familiar. But the warp drive should not correspond to any technology known to us. It therefore makes sense to take a closer look at the physics of Star Trek, which has become a trademark of the series, using this example [1, 2].

As you learn in the series, the Enterprise initially has a "pulse drive" that is used when only "short" distances have to be covered. This is a "normal" drive that, like rockets, is based on the recoil principle. Today's impulse drives are certainly unsuitable for bridging the gigantic distances between the stars in our Milky Way. But some time will pass until the 22nd century, when a spaceship named Enterprise sets off for the first time. By then, it could be argued, a super fuel, for example, or novel ion propulsion systems that generate energy from nuclear fusion could have been developed. After all, it is about science fiction and not what is already possible today. But the makers of Star Trek not only speculated imaginatively, they also attached great importance to not “bending” the laws of nature too much for the technology of the future. It is therefore permissible to ask why the "warp drive" is used instead of a "very fast" impulse drive to bridge the gigantic distances between the stars ...
