French Satellite Microscope May Challenge Theory of Relativity

by Sankalan Baidya
French Satellite Microscope

Theory of Relativity changed the whole face of Physics and changed the way looked at gravity. It was one of the most ground-breaking works over a century ago. However, is it correct? Today there are a group of people who really want to see the Theory of Relativity proven wrong. Who are these people? Well, they belong to the discipline of quantum mechanics. Interestingly, the French Satellite Microscope (yes, that’s the name – Microscope) is all set to prove the Theory of Relativity either right or wrong.

If Microscope manages to prove that Theory of Relativity is wrong, people of quantum mechanics will be the happiest people on planet Earth. However, if that really happens, all the physics that we have learned so far will be lost. Everything has to be redone from zero. But, if Microscope manages to prove the Theory of Relativity was correct, we can definitely live with our old daily life.

So, what is Microscope and what is it doing up there in space? What is its sole purpose? Who put it up there? Let us find out!

What is this French Satellite Microscope?

You must have heard of CNES. If not, it is the French Space Agency which is known as Centre National d’Etudes Spatiales and CNES is responsible for putting Microscope up there in space. Microscope is the name given to a small satellite or a microsatellite whose sole business up there is to test whether free fall is universal or not. The total lifespan of Microscope is only 2 years. The satellite has cost the French government 130 million Euros and was sent to space using Russian Soyuz rocket from French Guiana.

Now, what the hell is this universality of free fall? We will skip the unnecessary details and give you a brief. As per the Theory of Relativity, if two objects of different material and mass are dropped in vacuum, both of them will fall exactly at the same speed. To simplify further, the Equivalence Principle of the Theory of Relativity states that if, suppose, a feather and a lead ball are dropped at the same time and allowed to fall freely in perfect vacuum, both will fall down at the same speed irrespective of their actual mass. All the physics related to gravity that we have learned till date uses this Equivalence Principle.

So, why the hell one needs to test this principle in space?

That’s because there is no such thing called perfect vacuum on Earth. There will be absolutely no perturbations whatsoever in an orbiting satellite, that are usually found on Earth. Also, objects that will be allowed to fall freely will actually be in permanent and perfect free fall. This makes sense because, Einstein’s theory was theoretical and there was absolutely no practical proof. Microscope will either offer a proof and validate the theory or simply prove that it is incomplete.

What objects did French Satellite Microscope carry?

For the purpose of testing the Equivalence Principle, the satellite carried two cylinders – a platinum-rhodium alloy cylinder and a titanium cylinder. The golden cylinder you see in the image is the titanium one and the other one is that alloy cylinder. Now, during the experiment, if the two cylinders show slightest of speed differences in free fall, it will mean that the Theory of Relativity was not correct or better said, incomplete and whatever we learned so far was not correct as well.

According to Thibault Damour – a French physicist – if the experiment shows even slightest of deviations from Equivalence Principle, it will not necessarily mean that Einstein’s theory was completely incorrect. It will just mean that the theory of incomplete and there are other forces that actually contribute to gravity.

Hey Wait! There's More...

I have already proved that Einstein special theory of relativity is mathematically wrong. refer paper on In 1st chapter, I proved that applied force is less than acting force in SR & other math…

Free Fall

An elevator cabin is in free fall. On a plane, an observer is moving in a uniform linear motion horizontally. To him, the locus of the elevator is visible as a parabola.

On every atom of the former, inertial force is acting. On every atom of the latter, inertial force is not acting. Inertial force is not fictitious force. So, the two motions are not relative.

Equivalence Principle

Let’s start from accelerated motion. 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.《P.S.》Acceleration is not relative and inertial force is not fictitious. The two are corresponding qualitatively and quantitatively.

hiroji kurihara February 10, 2019 - 9:09 am

Equivalence principle

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. In each picture, vector of two forces (f = f’) acting on a point are drawn. 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).

Lorentz contraction

Plain waves of light (wavelength is constant) are coming from the upper right 45 degrees. Two bars of the same length are moving to the right and the left at the same speed. The number of waves hitting the bars is the same. Lorentz contraction is unthinkable.

Time dilation

A light source is shinning (frequency is constant). Two observers are receding from the light source (in the opposite direction). Two observers receive the same frequency. Where is the time dilation ?

An elevator in free fall

In it, action and reaction are working. The two are equal as a whole and at the selected infinite small area. By the way, in an elevator accelerated horizontally, the two are equal at every area.

Equivalence principle

Every inertial force is measurable. Every gravitational force is measurable also. Principally. In an elevator in free fall, there is no exception.

Hiroji kurihara May 30, 2019 - 5:14 am

Are the two indistinguishable? Vector of the two are opposite.

Hiroji kurihara May 31, 2019 - 5:33 am

Equivalence principle

In space, there are two gravitational sources (point source). In the middle of the two, a small area is selected. This area will be state of weightlessness (not zero gravity). Like an elevator in free fall.

Hiroji kurihara June 5, 2019 - 9:25 am


A website says, ” A charged particle is decelerated. And energy of motion is emitted as electro magnetic waves”. But, difference between deceleration and acceleration will be relative seen from inertial frames. Or, phenomenon bremsstrahlung depends on the absolute rest frame?

Hiroji kurihara July 2, 2019 - 5:30 am

Free fall

Inertial force ma is said to be virtual. If so, mg in free fall will be the same. And normal force will be virtual.

Vector of gravity and vector of inertial force are ubiquitous around us. And resultant forces are the same also. Why they make a big fuss on an elevator in free fall ?


Hiroji Kurihara July 12, 2019 - 2:48 am

Lorentz contraction

In a moving passenger car, MM experiment is being done. Between two light pathes diverged by a half mirror, there is considerable difference in length. Lorentz contraction will not stand up.

Hiroji Kurihara July 20, 2019 - 7:09 am

Constancy of speed of light

They say, it stands up on an observer in every inertial frame. Yes, when the light source shines in that frame, it is true.

Some man mistook this fact natural for a great discovery. And it is believed widely.

Hiroji kurihara September 25, 2019 - 2:45 am

Non free fall

Imagine an elevator cabin is falling in various density of air. Hydrodynamics tell the motion of these elevators. Equivalence principle is valid.

Hiroji kurihara September 25, 2019 - 2:50 am

Difference of motion

Difference of inertial motion and accelerated motion will be difference of motion relative to aether frame. And accelerated motion and inertial force are the front and back of a fact. Inertial force is not fictitious.

Hiroji kurihara September 25, 2019 - 10:20 am

Speed of light

To an observer floating in outer space, speed of light of a star is depending on the position on the celestial sphere. And when the light source is not distant, speed of light is depending on the motion of the source (according to the emission theory). In addition, by the motion of an observer.

Hiroji kurihara October 15, 2019 - 1:36 am

Equivalence principle
Two forces the same in strength are acting on a particle from the opposite. The two are inertial force, tension and gravity. Different combinations are three. Forget equivalence principle.

Hiroji kurihara October 17, 2019 - 5:23 am

Equivalence principle
From the roof of elevator cabin, a body is hung with a string. The elevator begins acceleration upward. Can the string distinguish between the gravity and inertial force ?

Perihelion shift of Mercury (I say again)

In an binary system (formed by main star and companion star), periapis is shifted also. Motion of companion star (apsidal shift) will be depending considerably on its size (mass is supposed to be the same). Common view (says main cause is pertubation of other planets) will be invalid.

Hiroji kurihara October 26, 2019 - 11:33 pm

Equivalence principle
An elevator in free fall is explained fully by Newton. There is no room for Einstein.

Hiroji kurihara November 1, 2019 - 3:13 am

Acceleration and non acceleration
On a plane (no friction), there is a body. Difference between the two above will be evident. It is enough to keep an eye on inertial force.

Hiroji kurihara November 1, 2019 - 3:16 am

Inertial force
Inertial force is depending on m. So, it is not fictitious.

Hiroji kurihara November 2, 2019 - 7:42 am

Free fall

Any inertial force is measurable. Any gravity is measurable. In an elevator cabin, these are measurable also.

Problem is limitted to the infinite small area. It is not physics.

Gravity gradient and infinite small area??

Gravity is gravity. Inertial force is inertial force. Resultant force is resultant force.

Basis of special relativity

We seem to measure c only by the light source situated on the same inertial frame. A web site says, reasonable basis of constancy of c cannot be found in web ( with three words).

Hiroji kurihara November 8, 2019 - 11:35 am

Constancy of c is nonsense (I say again)

1) There seems not to be basis (reliable) of constancy of c.
2) It is easy to disprove constancy of c. Many easy ways of disproval are possible.

Hiroji kurihara November 13, 2019 - 9:31 am

Inertial force

On a slope (no friction), a body is sliding down. Action is gravity mg. Then, how about the reaction ? It is resolved to two vectors. Inertial force is not fictitious.

Hiroji kurihara November 16, 2019 - 2:29 am

Reexamination of propagation of light (I say again)

In outer space, a mirror is reflecting a star light ray. Speed of reflected light relative to the mirror is constant. Speed of incident light relative to the mirror is not constant (the latter is constant relative to the aether).

Hiroji kurihara November 17, 2019 - 6:13 am

Inertial force is not fictitious

On a plane, there are two bodies. One is at a standstill, the other is accelerating. Acceleration (a) and inertial force (ma) are not fictitious.

There are two disks. One is not rotating, the other is rotating. Acceleration and inertial force both are not fictitious.

Hiroji kurihara November 20, 2019 - 3:52 am

Light is propagated in two ways

Propagation follows the emission theory is propagated in vaccum space and propagation follows aether is propagated in aether space. A mirror in outer space that is reflecting star light ray shows above.

Hiroji kurihara November 24, 2019 - 5:08 am

Space is rest frame

Into space, let us draw plural vectors of acceleration a. Space will be rest frame absolute.

Hiroji kurihara January 6, 2020 - 3:08 pm

Equivalence principle(I say again)

Vector of inertial force is shown by an arrow. Vector or gravity cannot be shown by an arrow generally. The two are different as facts of physics.

Hiroji kurihara February 15, 2020 - 7:01 am

Speed of light relative to mediums (water or air) is constant. Speed of light relative to aether (physical substance) is constant also. Aberrations show this.

Hiroji kurihara March 14, 2020 - 4:18 am

Accelerated to motion of light source

Light emitted from an accelerated source will follow instantaneous speed of the source. In short, light will scceed motion vector of the source. The emission theory imply the above.

I say again, the emission theory will be valid for a few seconds only after the emission. After this, light follows aether.

Hiroji kurihara March 19, 2020 - 7:13 am

Propagation of light (I say again)
Light is propagated in three ways (as follows)
1 In mediums, speed of light is c/n. MM experiment (done in air) is nonsense.
2 In outer space, a star light is reflected by a mirror. Speed of incident light is constant relative to aether.
3 In outer space, a star light is reflected by a mirror. Speed of reflected light is constant relative to the mirror.

In three pictures above each, speed of light relative to a moving observer follows Galilean transformation.

Perihelion shift of Mercury

Mercury revolving is divided in two (in hemisphere A facing the sun and the other B). Inertial force is A<B and gravity is A>B.

Above must be the most natural explanation of perihelion shift of Mercury. Because the value of perigee movement of the moon is remarkable (around 8.85 years). On the other hand, value of asteroids will not be found. Common explanation (main cause is other planets) is not acceptable.

Hiroji kurihara May 6, 2020 - 7:14 am

Perihelion shift of Mercury

Perihelion shift moves forward constantly. It cannot be explained by gravity of other planets.

On asteroids, no perihelion shift will be observed. Some size is needed.

Cause of perigee movement of the moon is written to be the sun. But it will be the same phenomenon to perihelion shift of planets. Not acceptable.

Hiroji kurihara May 8, 2020 - 6:28 am

Perihelion shift of Mercu

The value of perihelion shift of planets is constant. It will not be three body problem or many body problem. And it will be the same to binary star.

Hiroji kurihara May 12, 2020 - 6:02 am

Time dilation

Two passenger cars are passing each other. At the front of side wall of each car, the same light source (frequency is the same also) is settled and light ray is emitted backward at 45 degrees. Each ray is reflected by mirror sticked on the side wall wholely and is coming back. Time dilation is impossible.

Hiroji kurihara May 14, 2020 - 2:32 am

MM experiment

How about MM experiment done in still water ?

Hiroji kurihara May 18, 2020 - 7:46 am

Eddington experiment (on solar eclipce : 1919)

Eddington experiment is said to find the bending of star light by gravity of the sun. But the additional exam seems not to be done. Surface gravity of the sun is 28.02g and that of Jupiter is 2.53g. Gravity of position apart from each surface (at each radius) is a quater of surface gravity each. Experiment of Jupiter will be possible.

Hiroji kurihara May 20, 2020 - 3:41 am

Equivalence principle (I say again)

An elevator cabin is accelerating horizontally (no friction : at 2g). At every mass point (at every infinite small area), acceleration is 2g.
