Last December (’05), physicists held the 23rd Solvay Conference in Brussels, Belgium. Amongst the many topics covered in the conference was the subject matter of string theory. This theory combines the apparently irreconcilable domains of quantum physics and relativity. David Gross a Nobel Laureate made some startling statements about the state of physics including: “We don’t know what we are talking about” whilst referring to string theory as well as “The state of physics today is like it was when we were mystified by radioactivity.”
The Nobel Laureate is a heavyweight in this field having earned a prize for work on the strong nuclear force and he indicated that what is happening today is very similar to what happened at the 1911 Solvay meeting. Back then, radioactivity had recently been discovered and mass energy conservation was under assault because of its discovery. Quantum theory would be needed to solve these problems. Gross further commented that in 1911 “They were missing something absolutely fundamental,” as well as “we are missing perhaps something as profound as they were back then.”
Coming from a scientist with establishment credentials this is a damning statement about the state of current theoretical models and most notably string theory. This theoretical model is a means by which physicists replace the more commonly known particles of particle physics with one dimensional objects which are known as strings. These bizarre objects were first detected in 1968 through the insight and work of Gabriele Veneziano who was trying to comprehend the strong nuclear force.
Whilst meditating on the strong nuclear force Veneziano detected a similarity between the Euler Beta Function, named for the famed mathematician Leonhard Euler, and the strong force. Applying the aforementioned Beta Function to the strong force he was able to validate a direct correlation between the two. Interestingly enough, no one knew why Euler’s Beta worked so well in mapping the strong nuclear force data. A proposed solution to this dilemma would follow a few years later.
Almost two years later (1970), the scientists Nambu, Nielsen and Susskind provided a mathematical description which described the physical phenomena of why Euler’s Beta served as a graphical outline for the strong nuclear force. By modeling the strong nuclear forces as one dimensional strings they were able to show why it all seemed to work so well. However, several troubling inconsistencies were immediately seen on the horizon. The new theory had attached to it many implications that were in direct violation of empirical analyses. In other words, routine experimentation did not back up the new theory.
Needless to say, physicists romantic fascination with string theory ended almost as fast as it had begun only to be resuscitated a few years later by another ‘discovery.’ The worker of the miraculous salvation of the sweet dreams of modern physicists was known as the graviton. This elementary particle allegedly communicates gravitational forces throughout the universe.
The graviton is of course a ‘hypothetical’ particle that appears in what are known as quantum gravity systems. Unfortunately, the graviton has never ever been detected; it is as previously indicated a ‘mythical’ particle that fills the mind of the theorist with dreams of golden Nobel Prizes and perhaps his or her name on the periodic table of elements.
But back to the historical record. In 1974, the scientists Schwarz, Scherk and Yoneya reexamined strings so that the textures or patterns of strings and their associated vibrational properties were connected to the aforementioned ‘graviton.’ As a result of these investigations was born what is now called ‘bosonic string theory’ which is the ‘in vogue’ version of this theory. Having both open and closed strings as well as many new important problems which gave rise to unforeseen instabilities.
These problematical instabilities leading to many new difficulties which render the previous thinking as confused as we were when we started this discussion. Of course this all started from undetectable gravitons which arise from other theories equally untenable and inexplicable and so on. Thus was born string theory which was hoped would provide a complete picture of the basic fundamental principles of the universe.
Scientists had believed that once the shortcomings of particle physics had been left behind by the adoption of the exotic string theory, that a grand unified theory of everything would be an easily ascertainable goal. However, what they could not anticipate is that the theory that they hoped would produce a theory of everything would leave them more confused and frustrated than they were before they departed from particle physics.
The end result of string theory is that we know less and less and are becoming more and more confused. Of course, the argument could be made that further investigations will yield more relevant data whereby we will tweak the model to an eventual perfecting of our understanding of it. Or perhaps ‘We don’t know what we are talking about.’
Galaxies, the cosmos, astrophysics, observatories, telescopes: How do we possibly comprehend the reality that the universe is beyond measure, infinite, and endlessly mesmerizing?
We can’t; that’s why astronomy remains so completely fascinating. It’s the things in life we do not understand that most often draw our interest; that’s simply a natural human impulse — to be curious, to wonder and to want to be in awe of something far beyond and outside ourselves.
We know that stars, like everything else, live and die and that there are scientifically “correct” patterns in the remote sky that both perplex and bewitch us. If astronomy fascinates, it is because there exists in everyone a profound empathy with a world that is inaccessible in its complexity. Who among us has not felt, even fleetingly, spellbound by the immensity of this cosmos, this universe?
Modern observatories regularly function as educational centers, providing this feeling of entrancement by presenting the wonder of the cosmos directly to the audience, short-circuiting the intellect for an hour or so and uncovering the wonder at the magic of theuniverse; promoting a sensory, visceral feeling for the human condition and its place in the great book of the cosmos.
Astronomy, the science of stars, planets, galaxies, and black holes, is the oldest science, yet it is the most intriguing because the study of the universe will help answer the most important questions human beings can ask, such as:
How did the universe begin?
What is the structure of the universe?
How will the universe change in the future?
How do the planet Earth and its inhabitants fit into the larger universe of space and time?
Though we may never know the answers to these kinds of questions in our lifetime, we’re always thankful for those who will follow us, prepared, with a scientific brain, to one day provide answers — and maybe more — to humankind.
It’s difficult to understand our own galaxy, and we’re constantly “adding to it,” or discovering new frontiers and small, more distant planets than those we’re already familiar with. The sun, and the concept of the planets just in our galaxy alone, provoke wonder and all kinds of speculation. It’s food for our brain; it’s one of those applications of learning that so enthrall, it doesn’t seem like we’re “studying” anything. It’s an effortless exercise in the Unknown Sphere of the Universe.
What better way to pass the time, to postulate upon, to have an intellectually stimulating discussion, maybe with people you don’t even know yet?
And what about the theories of particle physics that have been developed in conjunction with the standard Big Bang model to explain the origin, evolution and
present structure of the universe?
What about the origins, evolution, interiors, and energy production of the stars themselves? How are they formed? Why? And we’ve all heard of “interacting galaxies,” but just what, exactly, does it mean? It all sounds like, well, a kind of heaven — a place we know exists, but that we cannot quite see or understand.
Then, there’s Newton’s laws, the concept of work and energy, momentum, gravitation, sound and light waves.
If you haven’t felt a slight thrill yet, it’s eitherbecause you already know about these atmospheric wonders, or you’ve been living under a local rock.
So get out there and Observe the Universe! It’s absolutely spellbinding!
Is Albert Einstein’s Special Relativity incompatible with the very equations upon which science’s greatest theory is built? New observations made by many scientists and engineers appear to contradict the great scientist’s ideas. Apparently there are implicit contradictions present within Relativity’s foundational ideas, documents and equations. One individual has even pointed that quotations from the 1905 document and Einstein’s contemporaries as well as interpretations of the Relativity equations clearly and concisely describe a confused and obviously erroneous theory. It is time therefore, for science to update its thinking on this theory with a comprehensive analysis of the history leading up to, during and after that revolutionary year of Special Relativity.
As this is the 100 year anniversary of the original release of Special Relativity, a review of the original assumptions, documents and ideas which led to the acceptance of this theory is timely and warranted. Every year millions of students are taught this theory without a critical analysis of Relativity. Relativity Theory consists of its two variants Special Relativity and General Relativity and is considered the cornerstone of modern physics.
Albert Einstein borrowed from the ideas of Fitzgerald, Lorentz and Voigt to create a new concept of the universe. His first work in this regard later came to be known as Special Relativity and contained many controversial ideas which today are considered axiomatic. Amongst these are Length Contraction, Time Dilation, the Twin Paradox and the equivalence of mass and energy summarized in the equation E=mc2.
This equation became the shining capstone of the new theory along with its first & second postulates, namely, that the laws of nature are the same from all perspectives and that the speed of light ‘c’ is constant in a vacuum regardless of perspective. Further, the theory also predicted an increase in mass with velocity. Numerous examples have been given of the ‘proof’ of the validity of Special Relativity.
Most notably, experiments using particle accelerators have sped particles to incredible velocities which apparently provide confirmation of Einstein’s theory. However, doubts remain in the scientific community who have never totally given up the comfort of a Newtonian world view. This is readily apparent in that they refer to the Newton’s ‘Law’ of Gravitation whilst Special Relativity (SR) and General Relativity (GR) are given the polite attribution ‘The Theory of’ or simply SR ‘theory’ and GR ‘theory.’ Einstein would continue working on the ideas of Special Relativity until producing the aforementioned even more controversial treatise.
In his later more comprehensive work called the Theory of General Relativity (1916), Einstein proposed a major re-thinking of cosmology. He conceived of a space time continuum that is curved by mass; in other words, planets, stars, galaxies and other stellar objects cause a curvature of space time. The movement of these objects are determined by the aforementioned curvature.
As a result of these ideas, our understanding of geometry, math, physics, science and the universe would never be the same. However, some scientists are reporting that speed of light is not constant from different experimental observations. One has even reported errors in the fundamental equations. If so, this would require a major rethinking of the known cosmological models and assumptions of modern physics.
