How can special relativity exist if there are no rigid bodies throughout the universe? We need breadth to have the Michelson Morley experiment. We can't do it if there is no breadth and no rigid bodies. The present concept of our Universe is that it consists of only point particles. Though assemblies of point particles make rigid bodies, those are not perfect rigid bodies. Because particles vibrate in rigid bodies depending on the temperature.
I started reading philosophy. And found out most of what I was thinking before are connected to it's subjects. I thought to jot down here, notes, as I read. Further, I have a liking on Physics, some notes are added about that subject.

Time dilation in Special Relativity
If
we can explain effects of consistency of velocity of light with fewer
tinkering of parameters we should stick with that theory. Because of
Occam's Razor. Tinkering with length or space is bad enough but
extending it to time is infraction. Because time we understand a very
little of it. Still we make comments like “trillionth of a
trillionth of a second after big bang”.

Dark Matter and Pulsars
Pulsars are believed to be neutron stars with high magnetic fields the focus electromagnetic waves in a narrow cone. When these systems rotate we detect electromagnetic pulses from radio telescopes.
There is an alternative explanation:
Consider a neutron star dualet moving away from earth at velocity greater than light. Also the earth is in it's plane of rotation of the stars. The stars of the dualet also moves in velocities greater than light. The system will be in negative space accept when the combined velocity towards earth is less than velocity of light. This happens only when the stars are at top for a brief window of time. At this time a pulse is emitted. This arrangement is possible if we assume the size of neutron star of diameter 20km moving at 2c, diameter of the orbit 6.5 km will produce 0.3 mil sec pulsar.
Several questions has to be answered if the above is to be true. What is happening to the energy emitted when the dualet is in the negative space? Suppose object other than earth but in the same line moves towards to the dualet in such a way that ducat's moving out velocity is less than c. Therefore is in positive space and should be visible to that object and not to earth? This is a baffling proposition. The photons that might reach earth are kept without traveling and the photons that can reach the object will be emitted. Therefore the earth and the object are directly inserting an influence on the dualet in emitting the electromagnetic radiation.
Another thing that can be assumed is what is emitted is not pure electromagnetic waves. It is something other than electromagnetic waves say dark energy. But by the actions of the observer converted to electromagnetic waves. Action of the observer is it's movement relative to these dark energy.
A light source will not emit dark energy. If we start moving grater than c relative to the source the energy will become dark energy and the source will become dark matter. Velocity of dark energy v is some v > c. So dark energy will have velocities that makes it travel across. Whenever some object moves in such a way that its velocity relative to dark energy is c it will become visible. Then this object will be traveling at velocity v < c relative to the source of dark energy.
Dark energy do not have a velocity component. It will originate from any source emitting energy. Visibility of energy will depend on the velocity of the observer relative to the source. If the velocity is greater then c the energy is will be dark energy and the source a dark object. If velocity is less then c energy will be electromagnetic radiation with velocity c.

Set of rules behavior
- Suppose a photon is emitted by an object that is not in dark, but by the time it reaches the observer the object accelerates and become dark matter, how will the observer see the photon? He will not see the photon. Because at the time of observance, the originator is in the dark. If we assume otherwise we need to think of some ether where the photon travels. This is contradicted by the constant speed of light in all reference frames.
- The energy is conserved and only a shift from dark to light happens.
- Observability of a EM radiation will depend on the relative velocity between the emitter and observer exactly at the time of observance. If it is greater then c the radiation wisps past the observer and will never be able to observe it. Another observer more distant in the same line of sight if his relative velocity is less than c will observer it. The radiation will go through the first observer as if it is nonexistent. The radiation for the first observer will be dark energy. The second observer will see the fist observer if relative velocity is less than c. But will also see radiation coming through the first observer as if it is nonexistent.
- There will be a violation of locality principal. Spooky action at distance will become true and very common.
- If the velocity between the observer and the emitter is less than c, everything will behave according to current classical laws, not special relativistic laws.
- Here no ether is assumed and EM radiation velocity is also assumed to be the constant c irrespective of observer movements. But the assumption of the velocity limit of c as predicted in Special Relativity is dropped.
- A message can be sent by the emitter to the observer, when the emitter moves in an out of dark space. However the message will be traveling at the velocity of light. Above example of pulsars is such an event. In the visible window the observer will see EM radiation. Hoover, at all times dark energy will be imitated. In the window of visibility it is converted to EM radiation.
- Space can consist by large amount of dark energy that zip past us with out any knowledge. Dark matter will be the objects that moves out from us at velocities greater than c.

Does Simaltanity is real
- Two events cannot happen in the same location. The location is a point in space. Two events may happen at the same point but not at the same time. Two events may happen at a single point in different times. Therefore it is irrelevant to the issue of simultaneity.
- Can simultaneity exist when two events happen at two different locations. There should be a method of measuring the time of occurrence for these two events in order to see whether two events are simultaneous.
- A solution is the one proposed by Einstein in the thought experiment of lightning bolts string two points of a moving train. If you fine tune the experiment we have to consider two photons emitted at two different points received by an observer at the midpoint. If the two photons reach the observer at the same instant we can say the two events that produced the photons are simultaneous.
- There are serious lapses in the earlier experiment.
- First we state that a concept called "simultaneity" exist. This concept is not "two events happen at two times and these two times are very close". Because this is not a concept it is just a statement. We can make such statements on anything. And there is no seriousness in these statements.
- If we say given two points there exists a single point called midpoint. This cannot be proved ever.
- Photons travel at the velocity of light. And according to quantum theory exact time of arrival cannot be ascertained.
- Therefore simultaneity is a priori concept. It cannot be proved to exist by using empirical methods. Worse than that even a thought experiment cannot be performed to show it exist. There is life after death is a priori statement. But a scientific theory like special relativity being based on such a concept is almost absurd.

Achilles and Tortoise Paradox
Achilles and Tortoise Paradox. The
paradox is Achilles and tortoise will have a race. The tortoise is
given a head start say 100 meters. Suppose both started running at
the same instant. It will take some time for Achilles to run the 100
meters. In this time the tortoise will have moved ahead say 10
meters. Then Achilles will need a further time to catch up the
tortoise. When Achilles reaches the next point the tortoise has moved
a further small distance. So, when Achilles reaches some point the
tortoise has reached, he will have to go farther. Therefore, Achilles
need to go to infinite number of points to overtake the tortoise,
which, is impossible. So, he will never overtake the tortoise.
In reality commonsense says this cannot
be, Achilles will easily overtake the tortoise. Therefore this is a
paradox.
Is it? The problem is that we assume
that space and time are continuous entities which can be divided
indefinitely. It is not so. Time and space are discrete. The
locomotion is not a smooth one where it can be divided in to
infinitely. The movement is in jumps. At one stage Achilles will jump
over the tortoise.

I am writing about Special Relativity,
so thought that I should give out some history about my association
with the subject of Special Relativity.
When I was an undergraduate at the
Colombo University Sri Lanka my pet subject was Special Relativity.
There was one Maths lecturer named Valentine Joseph lecturing on this
subject, I never missed his lectures, however, I missed almost all
other lectures in one year, playing bridge, chess, table tennis or
watching girls at the bus stop.
However love of Special Relativity was
my undoing. I loved the subject so much I was the only student in the
batch who tried to answer the questions about relativity in physics,
then messed up a calculation and was able to pass the test barley.
The result was instead a first class I go only a second upper. This
changed my life I was not absorbed to any academic post in the
university and I ended as a Tax Specialist in the Inland Revenue
Department of Sri Lanka.
Anyway this did not stop me thinking
about the universe and science. But to a lesser extent than economics
and business studies.
At age 63 now I am interested in
philosophy and read about the subject.

Negative Space
Whatever space we experience is
positive space. This space can be contracted when moving at a
velocity. (See Special Relativity is flawed written by me)
This theory states that moving objects
contracts. The transformation for object moving in x axis will be:
x
= xο,
y
= yο
√1-v²/c²,
z = zο
√1-v²/c²
One important aspect that I emphasize
in this theory not to make the mistake of special relativity where
length contracts in the moving frame and not so in the stationary
frame which leads to multiple contradictions and paradoxes.
If we need to avoid contradictions it
should be stated that the same happens in both frames. Therefore as
well as the moving object the stationary measuring instrument also
contracts and this contraction cannot therefore be measured by an
instrument.
It should be noted that the length
contraction here is different from Special Relativity. In Special
Relativity the contraction is along the line of velocity, but here it
is perpendicular to the line of movement. Further there is no Time
Dilation like in Special Relativity.
Several implications due to this
theory:
- Cosmic distance measurement may need to be revised. Because, of red shift galaxies further away will be moving faster than the near ones. Astronomical distance measurements are related to size of objects in space and the angle projected to earth.
- While moving objects contracts the objects moving in planes perpendicular to line of sight and the obits created by object circling another may remain same.
- If size can be measured in binary stars rotating in the same plane as line of sight, because the size may be smaller when moving in the line of sight than perpendicular to it. In other words binary stars in blue and red shifts appears smaller than when there is no shift.
- Creation of negative space when objects travel at velocities greater than light.
- May explain dark matter and dark energy by attributing velocities grater than c therefore objects moving to negative space which cannot be observed though the gravitational effect is evident to the surrounding space.
- Explain the existence of quasars with red shift z >4 and velocities greater than light.
- Moving clocks might be running slower or faster due to size contraction and changes in physical size.
- The age of the universe, the theory of big bang, the structure of the universe, finiteness of the universe etc may need to be rethought.
- This might give more answers than exotic Special Relativity which gives to more Fantasizeism.
- This will be the unification of space contraction and quantum theory.
- Explain variable stars.
