Black holes and dimensions...

We now take a break from the usual political fodder to bring you a glimpse into the wild landscape of what Floyd thinks about in his idle time...

So, I have decided I am not a normal person, in my idle time I don't go scheduling my coming week, thinking about games I'd like to play or TV shows or books I've read (well sometimes, but rarely compared to the other things that go through my mind). I think about things like world economics, political intrigue, and Unorthodox origin of the universe theories (and by unorthodox I mean both the creationists and most scientists would probably laugh at me). But here goes...


So, lets just look at a few principles of our known universe. Light travels at, well the speed of light, usually this is referred to as c, approximately 299,792,458 metres per second or 186,282 miles per second (from Wikipedia) Nothing we've seen really changes this speed much. Now... Black holes. Black holes are super dense clusters of matter, so dense in fact that it creates a gravitational field around the object that is so powerful that light itself, going as fast as it is going, actually can't escape once it's crossed a certain threshold of that gravitational field. That threshold is called the Event Horizon... So... Lets just say for theoretical purposes that you throw a light emitting object into the black hole and that it actually is able to keep emitting light all the way past the event horizon. The very moment it crosses the event horizon it emits a photon of light that is going in the exact opposite direction of the black hole.


How fast is that particle of light going? Well, according to our normal three dimensional thinking, so long as the particle of light stays at the event horizon, it is not moving at all, (unless it rotates around the surface of the event horizon orbiting the black hole, but that is a negligible detail...) But, light is always traveling at the speed of light, ya know approx 185,000 miles per second... So what is this particle of light traveling across to keep up the speed sufficient enough to stay at that event horizon?


This is where things start to get funky... (Break out your old R&B music) So the light is traveling across something, and that something is being pulled or stretched backwards into the black hole at the speed of light effectively making the particle of light stand still. Could it be that space itself is getting stretched and sucked into the black hole? Well, if that is true, then wouldn't everything eventually be pulled into a black hole? Not entirely, because we have recorded that space is being created in our own universe all the time. There is a noticeable red shift everywhere we look, like the universe is constantly expanding from every point at once... So lets just assume for the sake of argument that enough "Space" is being created that the black holes can stretch and suck in as much as they want and the rest of the universe will be will be fine. But if black holes are sucking the space in, what happens to it when it is in the black hole?


Time for the crazy leap. Lets just assume that our universe exists inside a black hole that is in another universe. We can never directly interact with that universe, the event horizon prevents us. But the space that is getting sucked into our black hole in the other universe would start showing up in our universe, and because it is hitting such an infinitesimally small target in the other universe, it would show up all over the place in our universe (I don't know like from every point simultaneously... manifesting itself as a slowly decelerating universal expansion) And the same would happen with any sort of electromagnetic radiation that landed in our black hole, it would show up everywhere at once in our universe (And manifest as a slowly cooling background radiation as our universe continues to expand) In which case, if these kinds of things were true, then that would mean that there are an infinite number of infinitely large universes, each containing an infinite number of black holes which would each be their own universe, all nested together in a never ending stack... Turtles not only all the way down, but all the way up too...


Yep It is a rough theory I know. That is how my brain works... A few screws loose but always an adventure. I'll stop there and give your brains some time to recuperate from encountering the mess that is this post. Till next time
