How would humans adapt to a world where the laws of physics have changed?

You see it all the time in science fiction. A small moonbase on the moon, a sprawling colony on Mars, or a coreward empire stretching across a galaxy. The problem is that it seems like a lot of this would violate the laws of physics as we know them.<br><br>One good example of this is ships in Star Trek and Star Wars and other science fiction series like that. They are able to travel faster than light without any one knowing how they accomplish this. According to Einstein's theory of general relativity, nothing with mass can travel at the speed of light. This severely limits how fast we can travel to other solar systems and galaxies.<br><br>Another good example is the aforementioned Mars colonies. If Mars was capable of sustaining a climate that would be hospitable to humans, it would have already. Mars receives 1/4 of the sunlight that Earth receives and has an atmosphere composed almost entirely of carbon dioxide. Even if humans were somehow able to magically manipulate the atmosphere of Mars to make it breathable, the planet would still be cold. It just does not receive enough sunlight to be habitable.<br><br>So how would humans adapt to a world where the laws of physics have changed?<br><br>&#x200B;<br><br>^{* Thanks to u/MLM_420_BLAZE_IT for the idea.}
