The scientific community has come a long way in understanding our Universe and how it works. Yet, there is still a lot we do not know. As Werner Heisenberg once so eloquently put it, "Not only is the universe stranger than we think, it is stranger than we can think." How do we make sense of our Universe and the nature of reality? Physics. You have probably taken a physics course or two. One way to think of physics is as the science of the Universe and everything in it. In fact, the word physics derives its name from the Greek word φύσις (phýsis), which translates as "nature". 

Along with chemistry and biology, physics is a hard science that uses testable predictions, hypotheses, experiments, mathematics, and modeling. Anyone studying or working in any subcategory of the subject is sure to tell you that the world of physics is exciting. It helps give us a peek behind the curtain of reality.

In many areas related to physics, such as particle physics, astrophysics, and quantum information science, the more we learn about the Universe, the stranger it seems to become. Perhaps that is why the science fiction genre has such a special place in modern culture, and among physicists. Today, we are going to look at some of the strangest mind-bending ideas that the world of physics propose, both running theories and thought experiments.
