A First Step Toward Understanding Relativity Conceptually

RELATIVITY IN HALF AN HOUR

Theoretical Physics for the Leisure Mind

by Chongo in collaboration with José

Acquire a deep understanding of relativity in a summary way, in only half and hour.  And, although it surely contradicts the common widespread opinion that relativity cannot be understood with common widespread conventional thinking, to the contrary, it can be very easily understand by anyone who can read and who can grasp a simple geometric principle: perpendicular. Although is commonly understood to be something very complex. Relativity is, at its heart, a very simple idea, when described in the context of a “flat,” two-dimensional world.

Now, anyone who can read can take the first step toward understanding what is, fundamentally, a very simple set of ideas.  Explore and grasp relativity, in an even easier way than Einstein did, in a universe with one dimension fewer than our own, within the confines of your own mind.  Imagine, just as Einstein himself did, just what it would be like to ride on a beam of light.  In this way, in the privacy of your own mind you can see just what Einstein saw, with the same ease with which he saw it, and just as Mister Einstein did, without having to step out of your imagination for even a moment.  No prerequisite education whatsoever is required and, the ideas so simple, that, just like Mister Einstein, one need not know hardly any math at all (in actual fact none) to grasp its principles.  This relativity book contains not a single mathematical symbol, as the principles are so “concrete,” none are ever needed. (Should the reader desire greater depth and complexity, though still with no math, then see Conceptual Relativity, which is a far more in-depth discussion of Einstein’s theory and what it means.)

 

 

 

 

EXCERPT:

 

How do we explain physical reality?  Where do we start, and with what do we begin, in order to take even the first step toward an explanation?  In explaining physical reality, do we really have anything else, except it, with which to initiate that explanation?  Is there ever anything else, except physical reality?  We might think there is more, perhaps by believing that our thoughts, memories, feelings, or dreams exist, somehow independently from physical reality.  In so believing, we ignore that we cannot even ‘imagine’ anything independent of physical reality (though we might, quite mistakenly, believe otherwise), any more than we can think, feel, or dream independently of it, because physical reality includes even the motions of our very thoughts, memories, feelings, and dreams, themselves, which are ALL also, just as physical – every bit as much – as anything in the universe.

“To even consider, legitimately, that our thoughts, memories, feelings, or dreams are somehow nonphysical, one must first identify precisely what it means for them, or for anything, to be so, and how, being nonphysical in character, they nonetheless express themselves in the most overtly physical ways – like speaking, that, so clearly being motion, makes all of our thoughts, memories, feelings, and dreams no less physical than any overt human action is; no less than ANY other kind of physical motion whatsoever in the universe is.  Stating matters clearly, anything that we might imagine being nonphysical affecting reality simply does not exist.

So, because physical reality is all that we really have (since, as stated, anything else cannot ever be expressed, described, or manifest in any other way except a physical one), we must choose physical reality’s observation as the first step toward its explanation.  If we do not choose observation as a first step, then we must choose either not to explain physical reality, or choose something 'else', though there seems to be nothing else that we can use that isn't its observation, by which to do so.  If we choose the latter, that is, choose something ‘else’, besides observation for explaining, we choose something that cannot, of course, ever be observed at all, not even indirectly (though we’re free to ‘believe’ otherwise).

In choosing observation, we choose something that we cannot really even imagine outside of the physical terms of the observations (or any permutations thereof: allegory) that are an outcome of our life experience or rearrangements and distortions of such experiences (as innate interpretive responses to these observations).  By choosing observation, as the first step toward explaining physical reality, we implicitly assume that physical reality is 'made' of what we observe, even if what we observe consists (as stated) only of what we think, or remember, or feel emotionally, or dream.  We further assume that physical reality, besides being made of all these things we observe ‘within’ ourselves, is made also of all those things that we observe outside of ourselves, through our sensory awareness.

“Thus, we begin, by assuming that physical reality is made of all things observed, be they observed internally or externally, directly (like seeing the print on the page that you are now reading) or indirectly (like seeing the reflection of ourselves [or anything], looking into a mirror).  In this way, we can use physical reality as a first step, so that it can explain itself, through our embracing its observation, in the most rigorous way that we can.  We will use physical reality, along with that part of it that is our imagination, as precisely as our current understanding allows, for describing our very observations themselves and the relationships existing between these observations (in a predictable and reproducible manner), which is what any meaningful explanation of physical reality must do, for it to explain anything that is genuinely, materially real (i.e. physically existing outside of our imagination).

 

 

 

 

 

EXCERPT:

                “Just as the great two-dimensional physicists discovering his or her two-dimensional version of the Theory of ‘Special’ Relativity could extend that theory and its straight-line geometry, by using this singularly simple geometry as a ‘special’ case “curve” for a broader, more complex geometry, that of two-dimensional ‘general’ relativity, so can we three-dimensional creatures do the same thing; which is exactly what the great three-dimensional physicist, Albert Einstein, did, by extending the description of special relativity’s effects of uniform motion (motion that does not change speed or direction) upon space (as opposed to a surface) and time, to non-uniform motion (motion that does change speed, direction, or both), and ‘equivalently’, to the effects of gravity, since the effects of gravity are absolutely indistinguishable from the effects of inertia.  By imagining special relativity’s straight lines as curved lines, we can create a conceptual description of space and time together (space-time), and a way to imagine the effects of mass, as the force of either inertia or gravity upon it.  In this way, we can logically derive the Theory of General Relativity in terms of a concept (namely, bending), just as Albert Einstein did the same (but describing the concepts more precisely using mathematics).”
