So a Portal to the Fifth Dimension has been found by scientists with Dark Matter, so there is that!
Dark matter is a hot topic in science loving circles as the concept is now a standard used in our understanding of modern physics. This topic also bleeds into quantum mechanics and even higher energy physics and phenomenology as well, due to the massive overlay of just how impactful the existence of Dark Matter and its applications can be, and so far there is mainly just theory.
After a new study the observation was made of dimension traveling fermions masses in many different particles, which are sent into the fifth dimensional warped space. This process created 'relics', or 'fermonic Dark Matter' which were left to be observed in the fifth dimension. So, its unknown how much Dark matter is stored in these pockets of reality around us.
The idea of communicating or tapping into this 'all around us', it would be huge. The whole thing so far is only theoretic because there is no way to actually observe any of this truly, for now as we have yet to invent the right gravitational detector it seems, oh and this was also done through a freakin' portal, and people say science is boring, yeah ok.
