ARTexplains The Quilted Multiverse

Using our current understanding of physics, we'll explore why the universe might actually be better referred to as a multiverse. Because this is a hotly debated topic, I have included some alternate viewpoints in the references below for your perusal.

I was asked on reddit about the foredeck and fivedeck example, and if it was oversimplified/incorrect. Here is my response: "Yes, you are correct that what I used in my example of the foredeck and fivedeck is based in (an incorrect example of) 'additive velocity' versus the expansion of space. The expansion of space is what actually causes vastly distant galaxies to be unable to communicate with each other. I knew that oversimplifying for the sake of an example would drive some people crazy which is why before the example I say "simplified" and after the example I say (paraphrasing) "of course, reality is more complicated than this example, especially because it's the expansion of space that drives things like galaxies apart from each other rather than spaceship engines." (The incorrect part is specifically ignoring special relativity for the sake of a simple example) My example was simply meant to say "Hey, isn't it wacky that the laws of the universe make it possible for objects that can never interact with each other to exist?" (But because it is incorrect, I wish I had used a different example) Of course if we wanted to get really technical, my example should have been a lot more complex involving special and general relativity explanations and the fact that spaceships will probably never ever go anywhere near fast enough to be useful in an example like this... which wouldn't have made for a great example :-\ Try not to let it drive you crazy, in the same way that lots of introductory physics problems tell you to ignore friction :-) Thanks for asking the tough questions, I love being kept on my toes by viewers!"
