IS IT TRUE THAT NEWTON'S GRAVITY IS NOT AS GOOD AS EINSTEIN'S GRAVITY?



“Imagination is more important than knowledge” (Albert Einstein)
Unfortunately, Einstein’s imagination lead him to the biggest blunder in modern physics for more than 100 years.

THE MOST IMPORTANT THING EINSTEIN HAD FAILED



When taking observe for finding the angle of bending of star light in the sky, knowing the altitude of star is just as important as measuring the time of moving celestial bodies. We must know the altitude of star quite exactly if observations are to be of any use. The reason for this is that the angle calculations all depend on the altitude of star.

FAST RADIO BURST (FRB)



ASTRONOMERS ON THE HUNT FOR MYSTERY DEEP SPACE SIGNALS JUST GOT A MAJOR BOOST

They’re mysterious bursts of radio waves from space that are over in a fraction of a second. Fast Radio Bursts (FRBs) are thought to occur many thousands of times a day, but since their first detection by the Parkes radio telescope a decade ago only 30 have been observed.

But once the Australian Square Kilometre Array Pathfinder (ASKAP) joined the hunt, we had our first new FRB after just three and half days of observing. This was soon followed by a further two FRBs. And the telescope is not even fully operational yet.

The fact that ASKAP detects FRBs so readily means it is now poised to tackle the big questions.

One of these is what causes an FRB in the first place. They are variously attributed by hard-nosed and self-respecting physicists to everything from microwave ovens, to the accidental transmissions of extraterrestrials making their first baby steps in interstellar exploration.

The astounding properties of these FRBs have so enthralled astronomers that, in the decade since their discovery, there are more theories than observed bursts.

FRBs are remarkable because they are outrageously bright in the radio spectrum yet appear extremely distant. As far as astronomers can tell, they come from a long way away—halfway across the observable universe or more. Because of that, whatever makes FRBs must be pretty special, unlike anything astronomers have ever seen.

What has astronomers really excited is the fossil record imprinted on each burst by the matter it encounters during its multibillion-year crossing of the universe.

Matter in space exerts a tiny amount drag on the radio waves as they hurtle across the universe, like the air drags on a fast-moving plane. But here’s the handy bit: the longer the radio waves, the more the drag.

By the time the radio waves arrive at our telescopes, the shorter waves arrive just before the longer ones. By measuring the time delay between the short waves and the longer ones, astronomers can work out how much matter a given burst has travelled through on its journey from whatever made it, to our telescope.

If we can find enough bursts, we can work out how much ordinary matter—the stuff you and I and all visible matter is made of—exists in the universe, and tally up its mass.

The best guess so far is that we are missing roughly half of all the normal matter, with the rest lying in the vast voids between the galaxies—the very regions so readily probed by FRBs.

Are FRBs the weigh stations of the cosmos?

Difficult to find and harder to pinpoint

There are a few reasons why we still have so many questions about FRBs. First, they are tricky to find. It takes the Parkes telescope around two weeks of constant watching to find a burst.

Worse, even when you’ve found one, many radio telescopes like Parkes can only pinpoint its location in the sky to a region about the size of the full Moon. If you want to work out which galaxy an FRB came from, you have hundreds to choose from within that area.

The ideal FRB detector needs both a large field of view and the ability to pinpoint events to a region one thousandth the area of the Moon. Until recently, no such radio telescope existed.

A jewel in the desert

Now it does in ASKAP, a radio telescope being built by the CSIRO (Commonwealth Scientific and Industrial Research Organisation) in Murchison Shire, 370km (230 miles) northeast of Geraldton in Western Australia. It’s actually a network of 36 antennas, each 12 metres in diameter.

What Happens If Gravity Probe B Succeded Test General Relativity?


The Gravity Probe B experiment was carried out in collaboration between Stanford University, NASA, Lockheed Martin and KACST.
On 4 May 2011, NASA announced the long-awaited results of Gravity Probe (GP-B), and a month later the results appeared in Phys. After more than 47 years and 750 million dollars, GP-B had succeeded in measuring the general relativistic geodetic and frame-dragging effects on orbiting gyroscopes. In this focus issue, CQG publishes a set of refereed papers that provide the complete details of the experiment, from design of the spacecraft to the final data analysis, thus bringing to a close an extraordinary chapter in experimental gravitation.

Use Equivalence Principle And You’ll Look Like Einstein’s Happiest Thought


Einstein’s happiest thought (1907): “For an observer falling freely from
the roof of a house, the gravitational field does not exist” (left).
Conversely (right), an observer in a closed box — such as an elevator or
spaceship — cannot tell whether his weight is due to gravity or acceleration

High School Students Easily Be Able to Understand Einstein’s Gravity is False



Albert Einstein may be a genius, or may be Einstein’s genius is overrated. But he is a human; every human has limit. It does not matter someone has a college degree or not, as a human can make a mistake in his life. Sometimes those with a college degree like to appear as a fool. For example, if a person who is known as an expert in physics says “I’m certain, Einstein has always been right”. Of course, his statement made him look stupid.
We’ll easily be able to understand Einstein’s theory of gravity was totally wrong; even if our education advanced only through high school. Why so, and what’s the reason? That’s because Einstein’s mistakes are also at the elementary level: he had no idea on the basic of astronomy.

WHY DIDN'T THEY KNOW NONSENSE?



 Prediction at 2017 solar eclipse, August 21, in USA
The first calculation of the deflection of light by mass was published by the German astronomer Johann Georg von Soldner in 1801. Soldner showed that rays from a distant star skimming the Sun’s surface would be deflected through an angle of about 0.9 seconds of arc, or one quarter of a thousandth of a degree. This angle corresponds to the apparent diameter of a compact disc (CD) viewed from a distance of about 30 kilometers (nearly 20 miles). Soldner’s calculations were based on Newton’s laws of motion and gravitation, and the assumption that light behaves like very fast moving particles. As far as we know, neither Soldner nor later astronomers attempted to verify this prediction, and for good reason: Such an attempt would have been far beyond the capability of early 19th century astronomical instruments.
Light deflection in general relativity. Over a century later, in the early 20th century, Einstein developed his theory of general relativity. Einstein calculated that the deflection predicted by his theory would be twice the Newtonian value.The following image shows the deflection of light rays that pass close to a spherical mass. To make the effect visible, this mass was chosen to have the same value as the Sun’s but to have a diameter five thousand times smaller (i.e., a density 125 billion times larger) than the Sun’s.(www.einstein-online.info).

A Confirmation of General Relativity Won The Nobel Prize!





Stephen Hawking’s writings and statements are often surprising. As a world-leading physicist, not infrequently his writings and statements make a bit of a stir in the science world. If not he who says; it must be considered as a joke. But because he said that; then it is considered serious and gets more attention. For example, the writings and statements of Stephen Hawking in Nature in the early of 2014: ‘There are No black holes’. A number of physicists and astrophysicists reacted strongly against his idea.

These Are Not Photos of Black Holes




SCIENTISTS HAVE PEERED INTO A BLACK HOLE AND TAKEN A PHOTO OF ITS EVENT HORIZON FOR THE VERY FIRST TIME. From the initial image returned, scientists should be able to test relativity. “If you know the mass of the black hole—and for Sagittarius A* we know that well—and if you know the distance of the black hole, which again we know well, then relativity predicts you will see that shadow and ring and that the ring will have a certain diameter and it will be near circular. That’s a test of relativity. If the shape isn’t circular or the wrong size, then relativity has made a prediction that has failed. That’s the first thing we’ll look at.” (Event Horizon Telescope)
Event horizon telescope will be useless; the same as radio telescope (VLBI), LIGO's twin detector and other. Einstein’s gravity (general relativity) was totally wrong (Astronomical Data Prove Spacetime Fiction)

Eclipse’s Data of 1919 -1973 Verify Einstein’s Prediction Really Doesn’t Work

Hans C. Ohanian’s Einstein’s Mistakes: The Human Failings of Genius:
Almost all of Einstein’s seminal works contain mistakes. Sometimes small mistakes — mere lapses of attention — sometimes fundamental failures to understand the subtleties of his own creations, and sometimes fatal mistakes that undermined the logic of his arguments.
The book was reviewed positively in a recent Wall Street Journal article.
A theoretical physicist by training, Mr. Ohanian doesn’t write like one. He recounts his chronicle of errors in clear and engaging prose, giving us in the process a short course in the history of modern physics and a witty and provocative account of his subject’s life. Anyone who has read the recent biographies of Einstein by Walter Isaacson or Jürgen Neffe may find some of the material familiar, but on the whole “Einstein’s Mistakes” is original and fresh. Nor is Mr. Ohanian one of those petty biographers who delight only in turning up the failings — or turning out the dirty laundry — of great men. Rather he notes Einstein’s errors for a purpose, showing us why his achievement was all the greater for them.(Divided by zero)

PREDICTIONS OF GENERAL RELATIVITY DON'T WORK



Experimental Evidence Predictions of General Relativity Don’t Work



Why Einstein will never be wrong. One of the benefits of being an astrophysicist is your weekly email from someone who claims to have “proven Einstein wrong”. These either contain no mathematical equations and use phrases such as “it is obvious that..”, or they are page after page of complex equations with dozens of scientific terms used in non-traditional ways. They all get deleted pretty quickly, not because astrophysicists are too indoctrinated in established theories, but because none of them acknowledge how theories get replaced.(Prof.Brian Koberlein).
Of course not, obviously not because astrophysicists are too indoctrinated in established theories, but because astrophycists (and physicists) has no experiences in celestial navigation as a navigator at sea (not less than two years).

WHAT IS THE MOST ACCURATE TELESCOPE?







Need to know the basic level of astronomy, in order to know that collecting data of stars - comparing data made at another time - can not be use to measure deviation of starlight. Measuring the angle in astronomy applies direct measuring and instantaneous.  It doesn't matter using a sophisticated software, if doesn't meet requirements in the basic principle of scientific method in the field of astronomy; should be classified as a non-scientific.

Thank to Sir Isaac Newton
The idea of “a small telescope” or a sextant employing a movable mirror was first conceived by Isaac Newton in 1700. Workable instruments were made in 1730; sextant in this form has been in use for 250 years, and will be used into the foreseeable future. The name is derived from the Latin sextant, or sixth part of a circle. Due to the arrangement of the optic, the sextant will actually measure angles up to one third of a circle, or 120 degrees. The octants and quadrant are similar instruments, with ranges of 90 and 180 degrees.
A sextant can also be used to measure the lunar distance between the moon and another celestial object (such as a star or planet) in order to determine Greenwich Mean Time and hence longitude. The principle of the instrument was first implemented around 1730 by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but it was also found later in the unpublished writings of Isaac Newton (1643–1727)-(wikipedia.org)
On the first glance you might think that a sextant looks pretty complicated, but it really isn’t. There are only three basic parts, as shown in figure below, and the parts of the “small telesope” are clearly described on wikipedia.
