excerpts from PHYSICS HAS ITS PRINCIPLES


"...physics has given up its principles. It has too long consorted with mathematicians, who have no such principles. Mathematics obviously has considerable value as a tool for describing the world. However, a strength of physics historically has been the discipline it brings to mathematics by relating directly to nature. Forgetting this has surely been to the detriment of progress in physics."

THE CAUSALITY PRINCIPLE

"Every effect has an antecedent, proximate cause."

NO TIME REVERSAL

"It follows that time travel into the past is not possible ... [If a] person appears in a time where he did not previously exist, that instantly violates any hope for conservation of matter or energy in the universe. Not only has more of both just been added to the past (displacing any substance that existed in that place previously), but the universe continues to have this supplmental mass and energy until their progenitors disappear from the present.
Another problem is that time travel must also involve travel through space. For example, the Earth is continuously traveling through space in its orbit around the Sun, in the Sun's orbit around the Galaxy ... If one could suddenly pop into the universe at a past time, how could one expect to find the Earth in space at that time? Time travel is therefore disallowed by the principles of physics."

NO TRUE "ACTION AT A DISTANCE"

""Proximate" means "physically in contact with". An effect can have many remote causes, but must have at least one proximate cause. The alternative would be a condition that one thing be able to affect another without the passabe of anything between the two ... this would be the logical equivalent of magic, a miracle, or the supernatural. This condition is called "action at a distance", and is forbidden by the causality principle because it is logically impossible.

Isaac Newton, whose Universal Law of Gravitation is implicitly based on action at a distance, left no doubt that he considered this a pragmatic approximation of reality when he said:
"That one body may act upon another at a distance through a vacuum, without the mediation of any thing else, by and through with their action and force may be conveyed from one to the other, is to me so great an absurdity, that I believe no man who has in philosophical matters a competent faculty of thinking, can ever fall into it."--Isaac Newton
"So reality requires that any action be conveyed from a remote cause to a target by means of some sort of action- carriers. It does not require that the carriers be visible or even detectable. But exist they must, and they, or some surrogate carriers, must come into contact with the target to transmit the action."
"Fields are not a form of action at a distance ... in any rigid body when one part of it is pushed a pressure wave propagates through it, conveying the push to all parts of the rigid body."

NO "CREATION EX NIHILO" [Big Bang prohibited]

"Something cannot come into existence out of nothing. In a sense, it is another manifestation of the causality principle because such creation would represent and effect without a cause ... the Big Bang begins with the ultimate creation-fron-nothing scenario - the mass, space, and time of the entire universe from nothing - as its first step. Creation ex nihilo is forbidden in physics because it requires a miracle. Everything that exists comes from something that existed before, that has grown, or fragmented, or changed form.
So-called spontaneous particle creation from vacuum need not violate this principle because the vacuum is not empty ... the vacuum is occupied by substance on a scale too small for us to yet detect in any form other than in Casimir-type experiments. The principle only requires that the ingredients from which something is made pre-exist, but not that we can discover them yet."

NO "DEMISE AD NIHIL"

"The counterpart of not allowing the creation of something from nothing is ... something cannot become nothing. [but it can change] its appearance or form."

THE FININTE CANNOT BECOME INFINITE and vice versa

"No matter how many finite things we may collect, their total number and total substance remain finite. Likewise, if something is truly infinite (such as the set of all integers), then no matter how we divide it, at least one piece must remain infinite. And no matter how many equal-sized pieces we divide it into, each will still have an infinite number of components.
A singularity is a point where something has become infinite. In astrophysics, it is a point where matter has collapsed into infinite density and infinitesimal volume. Singularities occur routinely in mathematics. But up to now, whenever a singularity occurs in an equation, some constraint always prevents a singularity from arising in nature."
"The mathematicians who have taken over the province of general relativity have ... advocated the existence of real singularities in nature at the centers of 'black holes'. Einstein himself, as a good physicist, never accepted the concept of black holes, and held that some new constraint would modify his equations in the future."
"... objects such as the 'black holes' presently attributed to GR are forbidden to exist by the principles of physics."

TANGIBLE, MATERIAL ENTITIES CANNOT OCCUPY THE SAME SPACE AT THE SAME TIME

"One property that distinguishes particles from waves is the ability of waves to pass through one another without any effect on each other. However, when a wave passes, the constituents comprising the medium that carries the wave do not travel with it, but rather just bob up-and-down or back-and-forth in place. The wave is transmitted by consituent collisions, which occur without co-location of constituents ever occurring."

COROLLARIES OF PRINCIPLES

"...nature has no singularities. If it did, matter could disappear from the universe ..."

"... there are no black holes in the traditional relativity sense of event horizons centered on a singularity."

"There was no Big Bang at the origin of the universe. The Big Bang also violates several physical principles: an effect with no antecedent, proximate cause; no singularities in nature; and no creation ex nihilo. If the universe really is expanding - an assumption very much in doubt - then something must limit how far back that expansion can be projected."

DEFINITIONS OF DIMENSIONS

"Mathematicians, lacking physical constraints, are free to imagine or invent unlimited numbers of dimensions, and to ascribe any properties to them they wish. So one hears often of parallel dimensions, hyper-dimensions, multiple time dimensions, more than three space dimensions, etc. It is easy to forget that such ideas are fictional concepts. We have not a single observation or experiment that cannot fully and completely be explained with three dimensions of space, one of time and one of mass or scale ... Occam's Razor then requires that we not invent extra physical dimensions unless and until some necessity arises - not convenience, but necessity."

"... dimensions [are] scales for the measurement of intervals."

"Moreover, scales for measurement are insubstantial; i.e., they have no substance. Therefore, a dimension cannot be affected by matter or by a force. There is clearly no necessity for having curved space.
"The term "space" should continue to be used with its classical meaning, the dimension for measuring separations. If we have a theory in which we might like "space" to expand or contract, we must choose a different word, because the meaning of the word "space" is reserved for a useful concept that can have no distortions. For example, we might then have to say that "a space-filling medium" expands or contracts. That grounds the discussion in reality, and eliminates the fantastic."

"Similar remarks apply to time ... time is simply a measure of change ... if time is not a physical thing that slows down with speed and stops for things moving at the speed of light, then it follows that the speed of light is not a speed limit for the universe."

"The five ordinary dimensions are always uniform, linear, and universal."

REPEALING PHYSICAL PRINCIPLES

"If we saw physical principles being violated, we could conclude with some certitude that we were experiencing a virtual reality. This raises an interesting philosophical challenge: How do we know our present reality is not a virtual one? Ultimately we are forced to act pragmatically and behave as if this reality is non-virtual because the consequences of doing otherwise are painful and catastrophic, to the best of our ability to predict them."
