U.S. Space & Rocket Center of Huntsville, AL

On a recent trip to Huntsville, AL, I was able to squeeze enough time for myself to visit the world famous U.S. Space & Rocket Center.  When you first walk into the museum, the first couple of exhibits are a little underwhelming, given the grandeur of the purpose of the site.  There is a display of patented inventions, then a tribute to Dr. Wernher von Braun.


It is interesting, but very museum-like.  Where's the rockets?

Well, once you are thru there, you can go outside!  Rockets!  Rockets!  Rockets!  None of them blasting off, but still impressive, nonetheless.








Of course, there is a lot more than just rockets that go into space.  Without giving too much away, here's a few more photos.  This is really a place you should visit just to see the shear scale of these massive machines.

"To good to be true" - Criticism of scientific studies grows

It is almost ironic, the other day I posted this article Reason Why I'm Skeptical of Skepticism which criticized over reliance on many study conclusions without actual supporting or valid data within the studies.  Now, just a few days later, there is a new published "study of studies" which reinforces the idea of being skeptical of scientific study conclusions, Excess Success for Psychology Articles in the Journal Science.  This study exposes that many studies in Psychology have issues, where the declared conclusions are simply "to good to be true" based on the strength of the data.  The inference being that there may be a general problem with all fields of science.
"Not every experiment is methodologically sound, and some experiments (even if methodologically sound) do not clarify the status of a theoretical idea. There is little reason to publish such experimental results, whether they are statistically significant or not. Unfortunately, in day-to-day scientific practice it is quite easy to interpret an unsuccessful outcome as being irrelevant to the theory or as being methodologically flawed and therefore not worth reporting."
In other words, data is cherry-picked in support of the theory rather than attempting to take contrary results into account.  This is basically throwing out the Scientific Method when it doesn't result in data this supports a theory.  In other cases, data collection is just too imprecise to form a suitable theory.  Kind of like garage-in-garbage-out.

I have a feeling a growing criticism of the current system is going to force changes into the process of study publishing and utilization.

Reason why I'm skeptical of Skepticism

There is a plague on modern science and Skepticism.  That plague is over reliance upon research reports.  Research report is a gathering of pre-existing data (the "re" in "research"), repurposed to find patterns.  The problem is that many research reports are created to find correlations in support of predetermined conclusions (assumptions).  Research reports are often formatted as scientific studies and published in science journals along side scientific studies that use the Scientific Method.

What is the Scientific Method?  First, wonder about a phenomenon and ask a question.  Conduct research on that question.  Then, construct a hypothesis (a proposed explanation for the phenomenon). A hypothesis must be formed in such a way to be tested for being  false (falsifiability). The subsequent test must be done in such a way as to try to disprove your hypothesis.  Only after all of this can you analyze your data and form a conclusion from that data.  The final step is to share your results for others to review and check, often in the form of their own studies.  For a study to have value, its results must be replicated by others.1

The Scientific Method is valuable because it helps eliminate incorrect explanations for a phenomenon.  For example, say someone as a hypothesis that lemons are yellow because someone paints them with yellow paint.  You can test this in any number of ways.  You can go to an orchard and watch the lemons grow, changing color as they mature.  You can buy a lemon at a store and cut it, looking for a layer of paint.  You can peel the lemon and send the skin to a lab to search for significant amounts of paint.  Any of these tests would prove the hypothesis false.  Someone else could create a new hypothesis about why lemons are yellow, knowing that the cause is not paint.

The limitation of an unscientific research report is that it only requires you to visit a grocery store to see that the lemons are yellow in order to confirm your assumption that they've been painted yellow by a person.

Research reports often lack several crucial steps compared to Scientific Method.  First, the purpose of a research report is often to collect data in support of a pre-existing assumption.  An assumption is different than a hypothesis because an assumption is not a proposed explanation for a phenomenon; rather an assumption is that there is a phenomenon ("someone is painting those lemons yellow", instead of asking "why are lemons yellow?").  Second, no test is performed in support of this assumption.  Data is unscientifically collected from different studies, reports and other sources rather than being the results of a direct test.  There is certainly no falsifiability test.  Third, the results of the collected data are often correlated to the original assumption rather than standing on their own within the conclusion.

What's wrong with correlation between data sets?  Correlation is an indicator, but it is not a identifier. The common phrase is "correlation is not causation."  It is extremely easy to correlate unrelated things.  There is a website dedicated to just this.  This is why the Scientific Method requires a falsifiability test.  It eliminates the reliance on correlation.

Now, this is not to say all research reports are bad.  A research report that uses the Scientific Method to analyze data in a way that can be demonstrated with falsifiability does have value.  But, it is very hard tell good reports apart from bad reports using quick Twitter or reddit title links.  You have to read the report to know if it has value or if it is pseudoscience.  You have to read the whole report because the report's title and conclusions often do not even match-up the data within the report.

This is where I run into issues with Skepticism.  Skepticism tends consider any conclusions of a published research report (in support of presumed consensus) to be the same as studies using the Scientific Method.  Opinions regarding concepts outside the presumed consensus are immediately rejected (even if they are published) without regard to the quality of the report or study.  I cannot count how many times I've read a promoted research report, only to find that the evidence in the report is based correlated cherry-picked data.  Blind acceptance of research report conclusions is a big problem with Skepticism, especially as it grows in popularity among Atheists and other non-religious folks.  I've seen seen sources such as "skeptic" magazines that site unscientific research reports as though they are undeniable fact.  It is a problem being exacerbated by the ease with which (mis)information flows on the Internet through various social media and various other media outlets.

Other reading

In researching this topic, I found a very interesting "study of studies" about the flaws in most studies, Why most published research findings are false. Nothing in my article here is based on this study, so take this as a completely different source.  It is worth the read, and more fuel for the fire to be skeptical, not just of Skepticism, but of anyone trying to use a "study" to promote a notion.

Sensless Sunday: Mammoth Star

  1. The last pyramids in Egypt where finished before the last of the Woolly Mammoths died out.1 2
  2. The World as we know it was designated to end by a Viking myth on 2/22/20143 and by a modern economist on 3/4/2014.4 The quote from War Games rings through my head right now about "We're still here! We're STILL HERE!".
  3. Our Solar System is traveling at an average speed of 514,000 mph relative to the Milky Way galactic center.5

Remote Stone

Of what world we wonder true?  Our lacking nature holds fast our corporeal soul upon the bosom of thriving abodes that guise the cradled womb.  In this place stand we, me and all others, bound not in chains but yoked hereto nonetheless.  Grand thrusting spears slice through the wondrous  blue veil, floating on the currents of bent universe beyond this round realm, bringing to the helm  fleshless anthropomorphized cold creatures to cast away the dark cloak, thus revealing remote stone for stone’s sake.

Notion: dimensional time eliminates need for branching universes

This post is only going to be a superficial discussion and isn't going to explain anything in any real depth. I'm trying to simplify advanced quantum physics in the best way a "lay" person can.

In 1957, Hugh Everett introduced the idea of branching universes to solve a problem we encountered regarding seemingly random choices that the elements of the universe (waveforms in particular) when observed. Sometimes light appears as a wave, sometimes as a particle, and there is no way to know which a head of time. Everett suggested that the light doesn't make a choice when is it forced into one form or the other. It is always both a wave and a particle. The Universe branches into two each time the light is observed and forced to make a choice. In one Universe, you observe light beam taking on wave behavior. In the other Universe, another-you observes the light take on a particle behavior. Thus, the idea of branching Universes says that a two Universes are created every time a choice like this is made. There's a certain bit of faith required to believe this, but pure math doesn't lie, right?


The challenge
Now, I'm no physicists. I'm not going to challenge the math that goes into this notion. It's been tested many times and found to be sound. However, math is nothing more than a numeric language that we created ourselves to parse out elements of the Universe to understand it in our terms. Keywords being "our terms".

Everett's assertions about branching Universes (or Many-worlds interpretation, as it is formally called) are based on time being both linear and two dimensional at the same time. Each branching Universe is 1 dimensional, created within 2 dimensional time, like branching lines being doodled on a piece of paper. Well, that means it could be said time is 1.5 dimensional. I know many physicists will cringe at my interpretation of branching Universes. However, at least from an intellectual point of view, this seems to me to be a reasonable simplification. My point is the the concept of branching Universes offers an unnecessarily complex and convoluted explanation for something as simple as a beam of light acting one way instead of another.

Spontaneous creation of matter and energy?
Another problem I have with branching Universes is this. Where is all the infinite energy coming from to create all these infinite branches? Infinite energy is the same as infinite mass (E=mc2). If the Universe really started off with all of this infinite energy, it would have immediately collapsed back on itself, never to grow in the first place. Or, if the energy didn't exist at the Big Bang, there's no mechanism now that can continuously double the energy within a Universe to spawn new versions of itself. Thermodynamics has yet to be disproved by quantum physics.

Why is gravity so heavy?
Yet another problem. If gravity exists outside of the Universe, as current understanding quantum physics now suggests, it would be impacted by the creation of new branches of the Universe. As such, even if infinite energy is being created on the fly (as opposed to being there at the start of the Universe), gravity would weaken so rapidly, its decaying influence on this Universe could be readily measured and would likely lead each Universe to fly apart to nothingness shortly after the Big Bang. There wouldn't be enough gravity to form a single dust particle, let alone entire galaxies.

Every point in the Universe knows about every other point, 13 billion light years away?
One more problem? Sure. For entire Universes to be created instantly and constantly by the actions of a single particle or waveform in a highly localized point, every bit of energy, every particle, everything that exists would have to be instantly duplicated. These means that every bit of energy, every particle, everything in existence would have to be in instantaneous communication with every other bit of energy, particle and every object in the Universe, 13 billion light years across! This creates a new problem! If the action of every particle in the Universe has the ability to replicate the entire Universe, the information of the Universe has to be immediately available to all points within the Universe at the same time. But if the Universe is constantly branching, there is no preferred frame of reference from which the Universe can be infinitely replicated! There's no sorting mechanism to give one choice a preference over another when they happen at the same time. This leads to yet another problem.

Branching causes information bottleneck
The very act of infinitely and instantly replicating the Universe would create huge gaps in information on whatever the current state Universe is in. Things happen simultaneously all the time. How are quadrillions of simultaneous actions supposed to be instantly reconciled to instantly form quadrillion x quadrillion Universes? Some suggest that the ends of the Universe (whatever is just beyond 13 billion light years in any direction) may already be out of touch with each other. This would make the Universe impossible to instantly resolve to form all of these simultaneous branches. Even if all information about the Universe is known to all points in the Universe at any given instant, there would be a measurable bottleneck of the branching activity. Time would slow down at an increasingly observable rate.

2D Time makes branching unnecessary anyway
Here's the kicker. If the Universe is 1 dimensionally branching within 2 dimensional time, then time is already considered 2 dimensional. If time is 2 dimensional, then there's no need for the branching to take place. If the Universe is a waveform in 2 dimensional time, the objects within it are smeared across this these two time dimensions. We are simply seeing a 1 dimensional view of our Universe intersecting with 2 dimensional time.

Ball passing through a plane acts the same as our view of time
This is similar to a 3 dimensional ball that passes through 2 dimensional plane. As the ball passes through the plane, an observer on the plane simply sees a line that grows, then shrinks. He doesn't see the ball itself. Depending on where the ball intersects the plane, the observer sees a shorter or longer line (even just a point). Any measurement of the line is just as valid as any other, but only the portion that intersects the plane can be measured at any one time. So, this is also true of the Universe if time is 2 dimensions, and the Universe is a waveform that intersects it at different points.  We simply see different view points of the same event each time we make an observation. There's nothing random about the observations! We just cannot see the whole shape in our limited view!

We aren't creating new branches of the Universe when the Universe "makes a choice". We are simply observing where our Universe is intersected by 2D time!
When we observe something that forces the Universe to "make a choice", it's not random. We are simply observing which portion of our Universe (or the element being observed) is currently intersecting within the 2 dimensional time. This doesn't mean that there aren't parallel Universes that resemble our own. It just means that those Universes have been there since the Big Bang (not branching), using a measurable portion of the Big Bang's energy for their formation, just as our Universe has.

To be clear, I offer the above as a notion to point to other interpretation of Quantum Physics. It's not meant to be the final word on anything, nor does it represent a tightly held belief of my own. I certainly haven't done any math to back any of this up. However, I do believe there are physicists that are already moving along similar paths of reasoning, so I'm trying to get the word out as the concept of branching Universes has been gaining momentum in recent years with very little in the way of observations to back it up.

Senseless Sunday: skin deep lunacy



  • The next leap year where Feburaury does not have a full moon is 25721.


  • The current definition of the term "Blue Moon" dates back to March 1946, in which Sky and Telescope magizine mistakenly misinterpreted the definition of the term from 1937 Maine Farmers' Almanac. "Blue Moon" originally referred to the third Full Moon in a season which has four Full Moons2.


  • Atheists outnumber all but nine organized religions in the World.


  • The skin of a polar bear is black. Though the fur appears white, it's actually clear.


  • More often, you will use more gas making a left turn than making a right turn.
