What if I told you that I’m building a train, but that this train is invisible? What if I told you that when it’s completed, this train will take masses of people from one thought experiment to the next? And what if I told you that this train is the next big thing; the one everyone’s been waiting for? Would you help me to build it, or just stick around and wait for the ride to arrive? Either way; it’s on its way, and you better brace yourself </;)
