Judging Special Theory of Relativity by Using Reality Criterion for Easy Universally Accepted

Tu Runsheng

[Abstract]There are "difficulty of rule contraction " and the "time difficulty" that cann't be explaind into "fail patadox" in special theory of relativity (STR).The reality principle is "objective reality at the same place have nothing to do with the moving state of an abserver".STR go against the reality principle.

Key words:Special theory of relativity,ruler contraction difficulty,reality principle,time difficulty,Doppler shift.

PACS:03.30.+p

Theory of super-string also can not solve "ruler contraction difficulty","time difficulty" and the problem which special theory of relativity (STR) go against objective reality.Reality principle are the conclusion which we have drawn from numerous facts.Theory of super-string sustain general theory of relativity ,but it does not permit that STR does not accord with the objective reality or reality principles.The problems in STR should not be evaded.

Body's shape (outline) qualitatively have nothing to do with observer's motion state.The coordinate of an events relative to the same inertial system quantitatively have nothing to do with the moving state of an observer.The happened events cann't be became into "not yet happened" only by observing .These are reality principles.They can be expressed that the objective reality at the same place have nothing to do with observer's moving state.Below examples all can express that STR go against the reality pinciples.

A train which intrinsic length is 10 metres was doing 0.866c on a roadbed.There is a big pit which intrinsic length is 8 metres.the pressure between the train and the roadbed is produced by light pressure.Observing in the roadbed ,the train shortens to 5 metres,the train can fall into the pit with ease.Observing in the train,the length of the pit shortens to 4 metres,the train can not fall into the pit.The train can fall into the pit or not ? This is the "ruler contraction difficulty" that conn't be explained into paradox.If ruler contraction is apparent,observing in Muon,we cann't explain the experimental result for Muon life using relativity principle.

When two inertial systems A and B meet,the readings of clocks a and b both are calibrated into zero.At the same time,clocks a and b moving along the gradual opening line at the same speed respectively.When the clocks a and b meet again,thire time readings are recorded.Which reading is greater? Based on STR we know:observing in A ,the speed of clock a is faster (or slower )than clock b,the reading of clock b is greater( or smaller )than clock a's;but obseving in B,the results are turned out contrary to observing in A;even if observing in the same inertial system (A or B),there are two diferent results.This just is "time difficulty" that cann't be explaind into paradox.It comes from the theory which recognize "the objective reality at the same place have something to do with the moving state of an observer".

In the Einstein's famous thinking experiment about relativistic simultaneity ,the photons or radiating to the midpoint are changed into the two annihilation photons .Observing in the roadbed,there is relative motion between the source and the midpoint of the train,the instrument at the midpoint of the train can measure the exat Doppler shift.The particals and antiparticals before annihilation contact with the train and the roadbed respectively.Thus we can not know which in system is the light source .The happened Doppler shift can not be removed by observing of the observer in the train .The observer in the train,also can recognize that the two events are happened at the same time.If you think that they are not simultaneous,you must neglect the Doppler shift or admit the measured Doppler shift to be not objective reality.Under the premise of light speed invariance only when the two conditions---Doppler shift is zero and the moments of receiving the photons coming from the two end are different---have be satisfied,we can confirm that the shining events at the two end are not simultaneous.Otherwise,the simultaneity definition just is the non-logical definition.

There is a balance of double arm in system K . The spread direction of the arm is parallel to
x-axis.There is an electromegnet under every steel hanging plate on the balance,the effort for the two electromagnets acting on the hanging plates are completely equal. When the two electromagnets are not started and the balance is equilibrium state,we use a brittle thread to tie the both end of the arm and the midpoint of the balance prop.Then we switch on the two
electromagnets at the same time,the coordinates of the two started events are at (0,0,0,0) and (l,0,0,0) separately (here l is equal to the length of the arm).Obsering in system K ,the state of the brittle thread is intact (don't break),but observing in system K 'whose x'-axis is parallel to x-axis and moving along x-axis,based on special relativity we know that the brittle thread is broken (as the two electromagnets exerting force on the two hanging plates are not simultaneos,the equilibrum of the balance is changed ).The photon saignal portraying the
existing state of the thread emitting from the thread can propagate towards in every direction .It must be received by the observers in all systems in principle.In other words,at a moment (or for a time interval),the state of a thread is acknowledged state,it has nothing to do with the moving state of observers in qualitative.It is thus clear that,the relativity of simultaneity must be apparent.If the relativity of simultaneity is apparent,we cann't guarantee that the relativity of time delay is objective .Since Einstein's subjective simultaneity and subjective equivalence (or appararent simultaneity and apparaent equivalence ) cann't accurately prophesy
the objective state of things,so the statement of thing cann't test and verify the subjective
simultaneity and the subjective equivalence,all objective experimental results cann' t be regarded as the strong evidence to test and verify STR.

There are two inertial systems A and B,there is a bare source S in A.First S send out a flash of light at the moment of T1 indicated by the clock in A (clock a),then S send out a flash of light at the moment of T2 indicated by clock a.The flash signal emitting from a flash point can propagate towards all directions.The wavefront can inclose into a ball (it is called wavefront ball (WFB) for short ).The two time flash of light can produce two WFB.Observing in A ,owing to S is rest,so we can see that WFB1 and WFB2 are the concentric balls all along.But observing in B,S is a moving source,acoording to that light speed has nothing to do with the moving state of ligth source,we can know that WFB1 and WFB2 are not concentric balls.If photons have materiality (this is doubtless),WFB1 and WFB2 are similar to two expanding balloons,they cann't be both concentric and non-concectric at the same momemt as two balloons do.The vision light of a shooting star is a shaft of light but isn't a rest point of light.It can express that the result for WFB1 and WFB2 to be not concentric balls is objective.Once two balls are not concentric balls in an inertial system,the distance between the two centre of ball cann't be completely eliminated by observing without interference.If the result for WFB1 and WFB2 to be concentric balls is objective,we can not see the two balls to be non-concentric obsering in
any other system,because two coincided points cann't be separated by observing without disruption.

There are three normal systoms A,B and C.The speed of C relative to A and B are 0.433c respectively.There is a pregnant woman at the origine of reach inertial coorinate system.The two women in A-system and in B-system are nearing each other at a speed of 0.866c and expecting their babies at the exact moment when their sweep each other.There is a calendar clock near
by every baby.The two calendar clocks are started from zero at them birth i.e. the reading is one year and the baby just is one year old.We call the events that the photons holding the information of "B-baby is two" strike the face of A-baby "events 3".According to STR,we can know that,observing in A,when B-baby is two,A-baby is 4,the spent time for the photons from B
to A is 4*0.866=3.464 years.Therefore,A-baby will discover that events 3 happen at the moment of 7.464 years indicated by A-clock,the coordinate of evnts 3 is (0,0,0,7.464).If we observe in C-system,A-baby also is 2 when B-baby is 2,the spend time for the photon from B to A is Tc,yet Ta=0.9014Tc.We have the relation of (0.433*４+0.433*Tc=Tc）,the solution is Ta =2.753 years.Therefore,C-observer can predict that events 3 happens at the time of 4.753 years indicated by A-clock.C-observer must agree that the coordinate of events 3 relative to A-system is (0,0,0,4.753).If the events 3 just is that the two kinds of photon signal of "B-baby is 2"and "A-Baby is 7.464" meet on A-clock,the two kinds of photon signal can propagate towards all directions from A-clock at the same time,all observers in other systems can receive the
two kinds of photon signal of "B-baby is 2" and "A-baby is 7.464" emitting simultaneously from the A-clock face in principle,every observer can admit the coordinate of events 3 in A-system to be (0,0,0,7.464).
