The Möbius Code (Part 1)
Anyone who has known me or read this website knows that I’m constantly attempting to decode for myself just how the universe reached the point it has currently reached. With each passing year there is new information that gets gathered into my tiny tiny brain (well I suppose compared to body size its not too shabby). So the following is, to the best of my current knowledge, how I think the universe has come to be. I’ll also discuss personal philosophies on how I feel it is best to examine the universe.
First we need to establish my views on time. Without them it makes it somewhat difficult to grasp just where everything begins (which will soon look like the wrong term to use). To do this we introduce an item that you can replicate with a strip of paper and a strip or two of tape. It’s nice because it is easy to make a personal one for examination.
A Möbius strip is a one sided object in a three dimensional world. We could argue that it does indeed have a small almost inconsequential side on its edge however that doesn’t change the point of the example. You have an object that appears to have two definitive sides and yet in actuality it only has one. If you happen to feel creative take a strip of paper and twist one of the ends a single time. Tape that end to the other end and you should have in your hands a Möbius strip. If you take a pen and press it in the middle of either side and run it along you will find that by the time your pen reaches the point you started at that you have a line on both sides of the paper and yet never had to lift the pen. You have essentially taken something that cognitively and visually appears to have two sides and proven with the wonders of a pen (or pencil) that it is merely an illusion where instead a one sided object actually stands.
So this is important (as I imagine you hoped it would be) because essentially this is how I view two separate real world issues. The first is that of time and the second is of the origin of the Universe. Now time is a wonderful thing, without it (or at least without the phenomena we call time) most events wouldn’t be nearly as interesting. In fact no events would be interesting named because there would be absolutely no events. It would just be a paused screen for all eternity, sort of like running Crysis on the average Jo’s PC (Nerd Joke).
I’m willing to argue that time itself has no beginning and just may end up never having an end. While with current knowledge of the Universe it does appear that eventually the Universe will stretch to such an extreme point that absolutely nothing will be moving any longer. Technically with the absence of all movement there is no longer time. Though there is a vast majority of the Universe that hasn’t currently been examined. The two prevailing arguments I have seen is that either we have goofed our calculations of Gravitation OR there is a matter that is not reactive to light. It is known as Dark Matter for a very good reason, it is literally absent of light. As far as I know nobody knows how Dark Matter reacts with all things around it or when presented with high levels of torsion. If we assume that the vast majority of the Universe is indeed Dark Matter it may indeed have a reactive property to that of a rubber band.
Which to me seems more likely. Why? Well it would seem extremely unlikely given the nature of everything that this process would only happen once. It is entirely possible that of the infinitely many times that this has gone on through its process that we just happen to be the ones that ended up in the ever expanding and eventually final universe. I’m skeptical but I won’t rule it out.
Time, like the Möbius strip, are examined as if they are two sided objects. In fact however I feel that Time is indeed one sided much like the adorable paper strip shown above. Time has and always will, by necessity, exist. There is little reason to believe otherwise, while this may seem naive (and I’m willing to agree it might be) it does however clear up some larger issues such as the origin of the Universe.
As you may have surmised the previous lecture essentially explains my understanding of the Universe as of now. Unless we get into the Quantum Level (and well outside of my realm of understanding at this time) the general rule of thumb is that matter is neither created nor destroyed at any time. Even a black hole doesn’t destroy matter, it merely crushes it to a near 0 point and flicks off fantastically small bits of itself until the black hole ceases to exist. Stephen Hawkins has some wonderful literature on this topic if you get interested.
With this fact in place it seems illogical to think that the Universe is any different (or time for that matter). Why would there be a special exception that serves absolutely no purpose. Indeed adding the special exception seems to do nothing more but support extraneous and entirely unhelpful theories about environments that the living human can never interact with (without the aid of some strong narcotics that is).
So I think this will do it for the first part of this series. What we’ve hopefully established is that something can give the illusion of multiple dimensions while instead being a single dimensional object. Time is one of those things, it never truly began and will likely never end. At best we could argue at the zero points (when all the matter in the Universe comes as close to 0 as it possibly can just before exploding) time temporarily ceases but that is purely speculation. Secondly somewhat necessarily of the previous statement the Universe is something that has for all intents and purposes always existed, indeed there is no reason to think that it didn’t.
Hope to see you all here for part 2 (and beyond).
Space is a Lively Place
http://www.spaceref.com/news/viewpr.html?pid=2474
This sort of news actually isn’t all that rare. It would appear that Europa more than likely has a serious amount of water underneath a thick layering of ice. Now the thing that people should always ask is if there is really ever a case where water exists and there is nothing living in it (without man-made interference). Even in the most extreme of aquatic conditions you will find some sort of life (no matter how small).
To me it is not a question of if there is life on Europa it is more a case of what life is on Europa. Considering that the major building blocks of life are 4 of the 5 most common elements in the universe (Something like hydrogen, nitrogen, oxygen, and carbon if I recall…might be off on one or two of those, the non-essential one is helium which isn’t very conducive to making friends. Assuming I didn’t get hydrogen and helium mixed up
Forgive me it is late).
So if the Earth had a warm core, tons of water, and formed life. Europa has a warm core, tons of water, and a shell of ice to protect it from just about anything harmful (not unlike our atmosphere) it makes one wonder just what is living under that shell. I’d be happy with just about anything, even a tiny fish like creature with a couple eyes and a really cute grin.
Food for thought
. I’d write more but I had to transit back home (vacation over). So you’ll start seeing far more educational posts starting Tuesday, taking a course on prehistoric organisms (IE Dinosaurs), psychopharmacology (study of drugs essentially may be changing this course), history and architecture of museums, and finally Greek Epics if memory servers
.
Good night all and happy interstellar hunting.
Black Holes and Human Brains
This is a bit of a thought experiment but I’ve come to think that perhaps the human brain is an example of evolutionary pit falling. I’d use a better term but my brain is kind of not running on all cylinders at the moment itself!
In the universe there are many objects of varying sizes and gravitational pulls. It would seem obvious that at a certain point that gravity becomes so great that it just continually compounds upon itself and creates an extremely massive singular point. Essentially whenever you are dealing with variable systems there seems to be a real world situation where there is a runaway train effect that creates otherwise seemingly impossible (or extremely unlikely events).
The Human brain seems to be another example of this. I have a strong feeling that the evolution of the human brain works in a similar fashion. This may be an event that is unlikely to happen again for quite sometime. When the original mutations hit and the earliest humans did grow larger brains (in whatever manner or region that they did) it must have been an extremely helpful mutation. This was much like that first bit of mass past the critical threshold in space. As more and more generations of this species reproduced the changes were reinforced more and more and the brain kept growing progressively larger.
I imagine larger brains are evolutionarily extremely handy (extreme being the popular theme this post) however they are not biologically primary mutations. There is some sort of required event, perhaps a very large amount of food to help lessen the necessity of other advantages (like strength or senses). The human skull did change allowing more space for the brain and that change was the weakening of the jaw muscles. Perhaps the major food source of Humans changed in some great manner and that change increased the amount of food ingested per human per life.
It’s an interesting question, while mutations are hardly intentional it does seem that certain mutations do cause absolutely amazing continual mutations that lead to extraordinary organisms.
Extra Note: I will warn you in advance. If these existential posts are a bit annoying for you the next week might be difficult for you!
I’m on vacation so it’s probably going to be a week of thought experiments. I will try my best to make them as inspirational as possible.
Literally Unfathomable
While some people might argue and say that they can indeed visualize the following I imagine most people would agree that you are only visualizing the most ambiguous features as the grandiose nature of the entire thing is just wild. The following update is inspired in massive part by Neil DeGrasse Tyson’s book Death by Black Hole: And Other Cosmic Quandaries. In fact you will find a section in the book (near the middle) that discusses the following in very entertaining detail, he has a spunky writing style that I’m envious of at times. However as is common here…I am digressing so back on topic.
For those that don’t know Satellites that are launched into space have two basic functions (permit this gross simplification), you have satellites that orbit the Earth and generally you have satellites (or as one reader reminded me: “Deep Space Probes” for the latter) that are launched as far as we can possibly get them to take pictures of all of the most amazing things in the universe. Before I go further to give you an idea of the distances we are talking here is an image from Voyager 1, it’s called “pale blue spot” or something like that. This is a picture of the Earth, yes that massive orb beneath your feet. It’s one of the most inspirational images I have ever seen:

I apologize for the large nature of the image but I feel seeing it like this helps keep with the flow and give you a second to just take it in. That right there is a dot amongst a sea of grain and color that represents everything you have ever physically come into contact with and indeed everything you can reasonably plan to physically touch in one lifetime. Quite humbling for me and part of the reason I’m so interested in space travel. I want to see every little dot.
Anyways the point of this is to illustrate the massive distance that these objects travel and indeed that do not even have the fuel necessary to make the distance. Anyone who has spun in a tea cup or a merry-go-round has noticed that the faster the object spins the more their body tries to launch itself at the speed of a tomahawk missile into the nearest hardest object (seriously why do I always hit something like a steel fence). Essentially this sort of thing happens on an absolutely massive scale in space, as an object passes by a massive object, if it doesn’t crash into the object it’ll slingshot via gravitational centrifugal force at very high speeds (the more massive the object the faster the slingshot).
NASA scientists do a bit of magic by sling shooting satellites passed every planet in the solar system to get them soaring out of our Galaxy. This sort of math and accuracy is so utterly amazing that NASA scientists seriously deserve a special day where they all get cake or something. I can barely keep my calendar straight.
At any rate this is only the beginning when looking at the magnificent power of gravity and centrifugal force. In the center of Galaxies like our own there are gargantuan (see Massive) black holes that kick so much ass and take so many names that they can launch entire suns at nearly the speed of light.
So think about that for a moment, imagine something the size of our sun speeding passed our Solar System at nearly the speed of light? Or try to imagine something that absolutely gargantuan soaring passed our solar system at really any speed, it would be an event that would likely be impossible to forget (possibly for very tragic reasons).
This sort of thing seems literally unfathomable, to visualize something essentially a million (That’s 1,000,000) times the size of Earth traveling at speeds that are essentially invisible to the naked eye (for the exception of the blanket of light that would probably cause many confused people to defecate themselves).
It’s food for thought, it reminds us how utterly miniscule we are, and I will go on the record as saying that is in no way a bad thing. We may mock ants but there are quite a few that could quite easily kill a full grown human, humanity has the amazing potential to take its small size and do things on the grandest of scales. We just need to set aside our petty and inconsequential bickering and try to look at the bigger picture.
Otherwise all that will remain is a pale blue dot on the vast galactic canvas.
The Life of Man
I know technically I should say “human” or “person” or something but frankly women on average already live 7 years longer than men, I’d say since I’m likely to die almost a decade sooner than a lady that I should be at least given the joy of popping my gender into the title. There will be at a time someday when its ironic.
There are so many reasons that the human life is just sadistically short. The wonderfully bright radioactive mass bursting brightly at the center of our universe lives for an estimated 10 billion years. That means that at best I’ll survive likely 1 hundred millionth the span of our sun. In the history of our universe a human life vanishes so quickly that its not even a blink, it’s hardly a trillionth of a blink if that. We take up something like two square feet of area when the very planet we are standing on takes 5 in a half quadrillion square feet…we are the tiniest of tiny ants upon a small rock in the middle of a vast expanse.
Some people talk about heaven, an afterlife, but I’m not satisfied. I don’t want an afterlife, I want this one. If I were to paint my own heaven ala, what dreams may come (good movie), it would merely be our current reality but with me immortal (and likely invulnerable). But all in all it would be the same thing. I love reading about this world, watching it, seeing it evolve, I want to watch the continents change and move. For new land masses to split and for others to crash into one another.
To see the first massive space ship begin its trek across space warping space and surviving the impact of hyper fast matter with nothing more than the shields wrapped around it like saran wrap. I would love to colonize my own planet, terraform it, and begin my own civilization. I want to watch a star die at the absolute smallest safe distance I can possibly imagine.
I want to see a time when we come to a point where we no longer are discovering the universe but making our own. I think in the end I just want to see a point in which the life of man doesn’t vanish into nothingness, to see a point where the irresponsible nature of a half dozen fanatics cannot nearly obliterate everything.
It is truly a frail and meek existence we life in, I hope to see a point in which life ends on our terms.
