So we are stuck in a linguistical conundrum, and Math is very rooted in those same Base Metaphors of the Embodied Mind. Taoist say that the Tao that can be spoken of is no the Tao. Finally, I ask, and subtly suggest in these comments, does the Embodied Mind and its natural ability to comprehend Math yield Meditational Experiences of Oneness with the Universe combined with the understanding that ultimately we are nothing in the face of everything, yet we are that everything? Einstein is still right.

Just as Eisteins theory took us beyond Newtons understanding. New theories like this will take us beyond Einsteins. My bs meter has hit the speed of infinity my attention tubes have melted and above all else the price of eggs in China has remained the same as yesterday. There is nothing called spacetime in nature, not to mention the existence of black holes as singularities of spacetime. All the theories based on relativistic spacetime model are wrong. Therefore, relativistic time is never the clock time i.

That is, a clock still measures the absolute time in special relativity. As relativistic time is not the physical time we measure with physical clocks, special relativity is wrong. The fact that physical time i. Besides the instruction as cause for everything imminent in existence, a function of polarity as residual provisional augmentations of space, light was created with space at its boundaries.

On a plain, imagine two gravity sources and fine circular waves gravity. On every point, vector of two gravity acts as a resultant force and there is a point where the resultant force disappears. Next, gravity source is one. Huge elevator cabin is in free fall. Fortunately, this elevator is empty. So, resultant force of gravity and inertial force that acts on every point of the structure does not disappear. Many substances solids, fluids, etc are moving in various accelerated motion. According to this motion, inertial force occurs. Imagine water of a current.

Involvement between inertial force and gravity will be on resultant force only. The two are corresponding qualitatively and quantitatively. Free fall of an elevator will be one of the problems of resultant force composition of forces. All will be explicable as a problem of resultant force.

There are two pictures. Direction of vectors is opposite right and left. In one picture, forces are gravity and gravity. In the other picture, gravity and inertial force. Two pictures will not be the same an infinite small area will be also.

Science will never be able to find out and understand many phenomena in the universe because it does not know the basis of the universe. First of all, no one knows what is matter, how and from what forms and how gravity and magnetism originate and who causes them. Besides this, science did not understand the sequence of formation and processes of the origin and disappearance of celestial bodies. Black holes are not the result of a star explosion. They are created under the influence of gravity, when in a given system, it accumulates so much mass that it represents a critical mass and critical gravity, when the matter returns to the form of the substance from which it was formed, and that substance is Aether that fills the infinite universe.

Who started to say gravitational acceleration?

### Instant Expert: General relativity

Is it a technical term really? It seems to be an adjective. Is there a difference between an acceleration caused by an ordinal force? If there is not a difference, a thing called gravitational acceleration will not exist. Allow me to show new URL of my web site service of geocities japan ends on Mar Every inertial force is measurable.

Every gravitational force is measurable also. In an elevator in free fall, there is no exception. In space, there are two gravitational sources point source. In the middle of the two, a small area is selected. This area will be a state of weightlessness not zero gravity. Like an elevator in free fall.

In the early s, a team led by scientists at MIT and Caltech initiated a research program to detect gravitational waves. Nevertheless, researchers have developed a technology that just might be able to see the tiny telltale signs of a ripple in the fabric of space as it rolls by Earth. The strategy is that a passing gravitational wave would alternately stretch and compress the two arms of each L, leaving an imprint on laser light racing up and down each arm.

In , LIGO was decommissioned, before any gravitational wave signatures had been detected—the apparatus almost certainly lacked the sensitivity necessary to record the tiny twitches caused by a gravitational wave reaching Earth. But now an advanced version of LIGO, an upgrade expected to be ten times as sensitive, is being implemented, and researchers anticipate that within a few years the detection of ripples in space caused by distant cosmic disturbances will be commonplace.

Success would be exciting not because anyone really doubts general relativity, but because confirmed links between the theory and observation can yield powerful new applications. A GPS device determines its location by measuring the travel time of signals received from various orbiting satellites. Physicists believe that the detection of gravitational waves has the capacity to generate its own application of profound importance: a new approach to observational astronomy.

Since the time of Galileo, we have turned telescopes skyward to gather light waves emitted by distant objects. The next phase of astronomy may very well center on gathering gravitational waves produced by distant cosmic upheavals, allowing us to probe the universe in a wholly new way. This is particularly exciting because waves of light could not penetrate the plasma that filled space until a few hundred thousand years after the Big Bang—but waves of gravity could.

Adopting that metaphor, how wonderful to imagine that the second centennial of general relativity may be cause for physicists to celebrate having finally heard the sounds of creation.

Gravity, said Einstein, actually moved matter along the curving pathways embodied in spacetime — paths imprinted by mass and energy themselves. As expressed decades later by the physicist John Archibald Wheeler, mass grips spacetime, telling it how to curve, and spacetime grips mass, telling it how to move. And his equations implied further slight deviations from Newtonian calculations. To physicists today, general relativity and gravity are essentially synonyms.

But general relativity is about more than just understanding gravity. General relativity inspired a new vision of the entire fabric of the cosmos. From general relativity flowed the realization that the universe is expanding, that it contains spacetime bottomless pits called black holes, that it is traversed by ripples in space triggered by cataclysmic collisions.

General relativity explains how the universe can obey physical laws that apply to any form of motion. And its implications are not limited to esoteric concerns on cosmic scales — it has its down-to-Earth impacts as well. Without general relativity, for instance, GPS devices would be worthless. On his road to general relativity, Einstein himself took many wrong turns.

Einstein had to learn new math and jettison common prejudices, such as the universal belief that Euclidean geometry described reality accurately. He struggled with distractions, both in his personal life and in physics problems posed by quantum theory. And he found that nature stubbornly refused to cooperate.

By he had essentially given up, believing that a partially successful attempt — a sort of general relativity lite — was the best that nature would allow. His theory began to solidify, and he swiftly composed four papers, one a week, during November By the last paper he had finally found the decisive equation that launched his gravitation revolution. Four years later, general relativity made Einstein himself a celebrity. If gravity curves space, he had realized early on, a light beam passing near a massive object say, the sun would be deflected from its course.

That deflection would shift the apparent position of the source of the light say, a distant star. During a solar eclipse, such a shift could be photographed and measured. As it turned out, some bending of light would have been expected even with Newtonian gravity, as Johann von Soldner had calculated unknown to Einstein more than a century earlier.

But Einstein predicted precisely twice as much bending as von Soldner had. Gravity deflects light just as general relativity requires. Gravitational lensing was first observed in , but Einstein had suspected its possibility in , even before his theory had been completed. But modern astronomical explorations proved the contrary. Einstein was also ambivalent about other consequences of general relativity. In , for instance, he raised the possibility of gravitational radiation — waves rippling through spacetime after a massive body abruptly changes its motion, as when colliding with another mass.

## The Theory of Relativity, Then and Now

But later Einstein changed his mind. In , he and Nathan Rosen submitted a paper arguing that such waves did not exist after all. But their paper contained a mistake. Astronomers have already detected another offspring of general relativity, black holes, throughout the cosmos. It was the first mathematical step toward describing black holes in space. It was , two years after his special theory of relativity had rewritten textbook notions about time and motion. But in real life, objects and people move in all sorts of nonuniform ways.

Let the air out of a balloon, for instance. Einstein wanted to extend relativity to all forms of accelerated motions. Then his happy thought in the patent office raised hope. A person falling freely accelerates toward the ground because of gravity but feels no force until impact. Therefore, Einstein realized, gravity and acceleration are two sides of a coin. The upward thrust of an accelerating rocket ship pins the occupants to the floor just as the gravitational pull of the Earth keeps your feet on the ground.

At first progress was slow. In special relativity, measures of space or time differ for different observers. But Minkowski showed that space and time combined — spacetime — yielded a mathematical description of events that all observers could agree on. Establishing such coordinates requires a frame of reference, or origin point. Different observers will choose different origins. By , Einstein realized that his goal would require abandoning Euclidean geometry.

Real space, he realized, could not conform to the idealized lines and angles of the textbooks. Gravity distorted the coordinates, just as a grid of straight lines on a rubber sheet would curve if you placed a heavy cannonball on it.

But Einstein did not possess the mathematical skills to cope with non-Euclidean geometry. Fortunately, his college friend Marcel Grossmann, an accomplished mathematician, was eager to help. It had one drawback, though — it worked for some coordinate systems, but not all possible systems. That made his original goal impossible. But Einstein seemed satisfied that he had done the best that nature would permit.

It turned out that there actually was something more beautiful. But to find it, Einstein had to move to Berlin. Born in Ulm, Germany, in , he moved when an infant to Munich and then as a teenager to Milan, Italy, having dropped out of high school.
