Pink is Dead!


… long live minus green!

From Brain Pickings:

If OK Go’s stop-motion color theory for Sesame Street met mathemagician Vi Hart’s hand-drawn math lessons, you’d get Minute Physics — charming and illuminating hand-illustrated science animations, like this fantastic explanation of how the color pink exists even though pink light doesn’t.

Speaking in terms of light, pink should probably be called ‘minus-green,’ because pink is just the leftovers of white light when you take out the green.”

For more on the curiosities and quirks of the science of perception, don’t forget Mark Changizi’s fascinating The Vision Revolution, which explores why we see the way we do.

Black Holes are ‘Portals to Other Universes’.


Black holes are ‘portals to other universes’, according to new quantum results.

According to Albert Einstein’s theory of general relativity, black holes are uninhabitable chasms of space-time that end in a “singularity,” or a mass of infinite density. It’s a place so bleak that even the laws of physics break down there. But what if black holes aren’t so forbidding? What if they are instead some kind of intergalactic stargate, or maybe even a passageway into a whole other universe?
It may sound like the premise for a clever science-fiction movie, but new calculations by quantum physicists now suggest that the stargate idea might actually be the better theory. According to the startling new results, black holes do not culminate in a singularity. Rather, they represent “portals to other universes,” reports New Scientist.
This new theory is based on a concept known as ‘loop quantum gravity’ (or LQG). It was first formulated as a way of merging standard quantum mechanics and standard general relativity, in order to remedy incompatibilities between the two fields. Basically, LQG proposes that spacetime is granular, or atomic, in nature; It is made up of miniscule, indivisible chunks about the same size as the Planck length — which roughly amounts to 10-35 meters in size.
Researchers Jorge Pullin from Lousiana State University, and Rodolfo Gambini from the University of the Republic in Montevideo, Uruguay, crunched the numbers to see what would happen inside a black hole under the parameters of LQG. What they found was far different from what happens according to general relativity alone: there was no singularity. Instead, just as the black hole began to squeeze tight, it suddenly loosened its grip again, as if a door was being opened.
It might help to conceptualize exactly what this means if you imagine yourself traveling into a black hole. Under general relativity, falling into a black hole is, in some ways, much like falling into a very deep pit that has a bottom, only instead of hitting the bottom, you get pressed into a single point — a singularity — of infinite density. With both the deep pit and the black hole, there is no “other side.” The bottom stops your fall through the pit, and the singularity “stops” your fall through the black hole (or at least, at the singularity it no longer makes sense to say you’re “falling”).
Your experience would be much different traveling into a black hole according to LQG, however. At first you might not notice the difference: gravity would increase rapidly. But just as you were nearing what ought to be the black hole’s core — just as you’re expecting to be squashed into the singularity — gravity would instead begin to decrease. It would be as if you were swallowed, only to be spit out on the other side.

OCEANIC BLACK HOLES FOUND IN SOUTHERN ATLANTIC.
 (http://ow.ly/o7UqG): Black holes are a tear in the fabric of space-time from which nothing escapes, not even light. They take on a mythic significance in popular culture as portals to alternate dimensions or grave threats to space travel. Astronomers are certain they exist out there in the universe, formed by the collapse of dead stars. Now, physicists have found mathematical analogs to black holes here on Earth, specifically in the southern Atlantic Ocean where eddies whirl about. Are we going to have our oceans SUCKED UP?! No. But they’ll still be pretty interesting: http://ow.ly/o7UqG

Ralphie quote:
 
“There’s been a breakthrough in my procrastination process. My progress is proceeding at lightning speed towards its starting point.
I am to inertia what Einstein was to physics!”

I might even say that I have just invented Quantum Procrastination.

I Will Be.


Cosmic dust of the Andromeda Galaxy as reveale...

1. Time is a riddle:

About a year ago I asked myself the question: what is time? I told myself that the answer to this riddle is the key to innumerable mysteries. My subconscious has been working on this enigma ever since and I have finally seen a light at the end of the tunnel. I have come to some conclusions that befuddle me even more.

2. I am legion:

Some time ago I wrote: I am not, I never was and I will be… forever changing. I am a million persons to a million different people and more. I am a galaxy of swirling neurons, etc. in my own right. I am a purely subjective and changing perception of myself to myself. I am less than a speck of dust in relation to the enormity of the universe.

3. Relativity:

No thing is nothing and everything exists in relation to everything else. The abstract notion of 3 in a universe of 10 is not the same as 3 in a universe of 11. 3 changes all the while in relationship to an endless universe of numbers. I am a part of Andromeda, in the sense that I am an ever-changing energy being that is in physical contact with the universe, which includes Andromeda, which is also ever-changing, as is everything in between.

4. The times they are a-changing:

Everything, everywhere that was in the past is gone and will never return. It is forever being replaced by an ever-changing future. When we see a mountain, then the range that was there a hundred thousand years ago is gone forever through erosion and so forth, but so it is with everything. When we see a chair, the chair that was there a minute ago is gone to be replaced by an older chair in a newer future. This chair is also slowly decaying and undergoing any number of forces, such as gravity, magnetism, etcetera.

The present tense as we know it, the now, makes no sense either, because there is no point in time that can be caught or frozen, except in our inaccurate memories or fantasy. The only reality is change. We, and everyone and everything in the universe, are defined by our relationship to everyone and everything else in the universe, which is constantly changing. When we say that we live in the now, we are merely conscious of the changing nature of all things and are sharing in it.

5. Labels are lies:

A line is not a line, for it is a collection of dots between point A and point B that can NEVER be taken out of context of the whole and as the whole is ever-changing, the line changes with it. Remember that the places where point A and B are located in the universe are forever moving with that shifting universe. On Earth, they would move through rotation of the planet, which circles around the Sun, etcetera. And it goes even further than that. If you assume that the universe is expanding, then both points would be forever expanding with it.

Labels are an attempt to force order on the universe or to freeze-frame it and does not work. It’s like naming one grain of sand on the coast of the continent of Africa. Remember the parable about the pond forever changing with the pebble that was thrown into it? It goes further than that! The pond is a lie, a mental construct that exists only in our minds. In reality the pond is a cosmos in itself, full of living organisms and eroding walls, taking on more moisture or evaporating it all the while.

6. Jehovah:

The proper name of God in Hebrew translates into ‘I will be’ or in other words: ‘I, the whole of the universe, am forever changing’! I, the author, doubt everything but change. I have only questions and only one measly answer, which may be untrue aswell. Blessed be.

About Gravity and Density.


Gravity well plot

Gravity well plot (Photo credit: Wikipedia) You see, it’s a plot!

I’m at present reading a novel in which is explained the mathematical and geometrical proof of gravity. At least, I assume it is!

Yet again, I am confirmed in my unshakable belief that I am completely and utterly thick, because I understood jack shit about it, not one solitary iota, bupkes, zilch.

First I thought I would ask someone to explain it to me in laymen’s terms, but then I realised that this would not do. Look at the term laymen, it has the verb ‘to lay’ in it, which means ‘to put down’.

No, Sir! I beg to differ. The degree of my stupidity is such that, if you were to try to make me understand, you would not have to put me down, but instead you would have to treat me as someone who has been deceased for quite some time!

Thus, the only ones to bring me any measure of enlightenment in the matter would be either Jesus H. Christ or God the Father Himself. As I am very much in doubt as to whether they will take the time to resurrect my mentos defunctos, I shall stick to my comfortable theory that gravity has everything to do with superglue.

It’s either that or await the Second Coming, but I think I’ll be gone by then!

Lifting the Veil of Illusion


Quantum-atom

Quantum-atom (Photo credit: Wikipedia) Looks like a boob to me!

From Unlocking the Science of Spirit.

When we see a situation or a thing, what is it that we see?  A thing is itself, of course, some philosophers would say.  Yet, what we see is what we interpret through our eyes, and what we experience is a function of mental cognition and the operation of our senses.  Using the example of accepting the physical world only, we can show that what one sees is not necessarily an objective physical truth:  think about color blindness or dyslexia.  Our nerves sense stimuli from that which they are designed to sense, and they send a signal through the body for the brain to interpret and then enter into consciousness.  We only know that something is true if we are conscious of what it is that we are perceiving.  So, what about the amputee of a leg that feels their limb and yet has none?  You may point out that these are extreme examples, but they are not.

The entire experience of our physical life, among other things, is based upon the animation of atoms, elements, plants, animals and the vessel we call our body.  We say animation, because quantum physics has shown that everything that exists in the physical reality has been shown to be a unified field of oscillating waves.  Whether alive, or inanimate, everything is in constant movement.  Behind all movement is force, or life force.  The primal essence that makes a being alive physically is different than that of an atom, but life its very self is dependent on the atom being in motion.  Simply, there is no such thing as stillness in the physical realm of existence.

What we see is not what we get.  We cannot see, with our naked eyes, inside an atom, or a single cell protozoan.  There is an entire universe in every element or form of life and its respective subcomponents.  Limiting reality to the physical senses and to a logical interpretation of the seen is wholly inadequate from which to judge or innovate in the world we live.  Semiconductors, optical science, radio waves, nano-technology, bio-technology, chemistry, biology and many other fields are based on knowledge of the unseen.

Time Babble…


Babble

Scientific question:

It is said, by some very bright minds indeed, that one particle can be in two(or more?) different places at the same time. But Ralphie does so like to be contrary!

What if I proposed that one particle can NOT be in two different places at the SAME time? What if our perception of time were flawed and this example of a particle is actually in two different places in two different timeflows?

What do we know about time anyway, really? It SEEMS to be forever going forward, but does it? Did not Einstein prove that travelling backwards in time is theoretically possible? So, what if there were two(or more) streams of time, one flowing forward and one flowing backwards?

What was the question? Who is going to prove my point?

P.S.: I’ve lost my own thread here, but it is fun to think about such things.

Another Ralphism!

Multi-Purpose Particles.


Sinclair 48K ZX Spectrum computer (1982)

What if you had a kind of particle, that had different qualities(or properties) that could be programmed irrespective of each other? If you then developed the software to read each different property, you would end up with a simultaneous multi-use system.

Along the same lines: you could have two movies running on the same screen. The first would use the normal spectrum, to which our eyes are accustomed and the second could use e.g. infrared, which could be watched, using a special filter(spectacles).

Never mind me! I´m probably talking out of my earhole again. Ralphie does get some strange ideas sometimes.

What is Time?


Illusions (Bach novel)

Illusions (Bach novel) (Photo credit: Wikipedia)

Time is the key, I think. If we could only understand the true nature of time, there wouldn´t be many secrets left. It´s just an intuition. But my brain feels like it´s swimming in molasses. I may find the answer, but it will probably take time. Richard Bach said: “If you argue for your limitations, then for sure, they´re yours!”

But maybe my limitations are mother nature´s way of safeguarding me from making even more monumental mistakes. Let´s say I could move mountains, just by thinking it. Where would I put them? I wouldn´t want to squash anything. I suppose I could suspend them in mid-air, but then the birds would fly into them. No, it´s better to leave the mountains where they are. They must be there for a purpose.

I was also thinking about myself, as an example. I read somewhere, that I am made up of several parts, like everyone else. I forget how many. There´s my body, my aura, my soul and some more bits and pieces. What if all these separate parts were part of different streams of time?

For example, my lifetime is but a moment in the time frame of my soul. With practice, I could probably move from one plane of time to the next. But how? Creative visualisation might be the answer.

Obstacles and problems is what life is all about. Without them, where would you be? It´s the road that matters, not the goal. Once you´ve conquered one goal, then what? You immediately need a new one. I wouldn´t even want to imagine knowing everything. What to do then, where to go? NO, I need my limitations. They keep me sane or is it zany? Haha!
