Scientists are searching for a mirror universe
The most intriguing about stories such as this is that our own ignorance on topics such as e.g. dark matter will, at some point in the future, be something a fresh grad will look back on with bemusement - how could we not possibly have managed to discover [x] as it gradually comes to be seen as self evident? This is long since the case for Newtonian mechanics which are now the domain of secondary education, and is already starting to become the case for relativity for those of sufficient education.<p>It&#x27;s kind of an interesting thought experiment to try to put yourself in the mindset of a people before the discovery of something and trying to imagine how you would have perceived the world and if you yourself might have conceived of such notions. For instance the idea that all objects fall at the same rate of speed is something that&#x27;s oddly enough an extremely recent discovery. The tale of the apple falling on Newton&#x27;s head dates to but 350 years ago. We, of today, are separated by then by little more than about 4 lifetimes.<p>It feels at times that science progresses through 1% genius and 99% creativity. Newton&#x27;s gravity is, relative to the times, no more simple or complex than Einstein&#x27;s gravity and undoubtedly whatever we may eventually find to be the source of dark matter. The tricky part is that the universe has this habit of requiring us to cast aside what we think we know and look towards paths that seem insane. A feather falls at the same rate of speed as a bowling ball? Time itself can move differently for people in the same location based upon their relative velocities? Physical distances can literally contract or expand again for people in the same location and again based on their relative velocities? Objects themselves can bend what seems to be emptiness and, in turn, bend light itself (to say nothing of also having an impact on time)? These ideas are mostly so difficult to develop not because of mathematical or technical problems, but because they sound insane. It&#x27;s really quite a blessing for the inquisitive and creative that we seem to live in a universe that prides itself in as being as defiant of intuition as it possibly can.
