None. Perceptions are like fingerprints, inexplicably unique.
Ex: Jane, Dick, Tom and Harry are sitting around a table, looking at a glass of water in the center. Jane sees the lights of the kitchen reflecting in the water. Dick sees the dust that's settling at the bottom of the glass. Tom sees his grandmother's 50th birthday party, when a similar glass shattered on the floor. And Harry, who walked a mile to get there, is pretty damn thirsty and waiting for the game to be over so he can have a drink.
All observations are dependent upon the person's vantage point as well as the reference information locked in each observer's brain. Since no two people can stand in exactly the same spot and have the exact same experiences, their observations can never be exactly the same. They can be similar (i.e. everyone can look at a glass of water), but no two people will ever see exactly the same thing.

The speed of light in Free space has the same value for all observers.
What else can I help you with?
What is the difference between Galilean relativity and Einsteinian relativity?
Galilean relativity asserts that the passage of time is the same for all observers. Einsteinian relativity does not claim universal time for all observers. Instead, it asserts that the speed of light and the fundamental laws of physics are the same for all observers.
What are the quantities of a scientist?
Did you mean qualities? Quantities of a scientist makes no sense at all.
The part of an experiment in which all conditions are kept the same is the?
The answer is the constant variables because they always stay the same.
Unit measurement of force?
The international unit of force is the Newton.
What unit is used to measure rainfall?
A milliliter is the best unit of capacity needed to measure a drop of rain. Milliliters are used to quantify very small units of a liquid.
What is the difference between Galilean relativity and Einsteinian relativity?
Galilean relativity asserts that the passage of time is the same for all observers. Einsteinian relativity does not claim universal time for all observers. Instead, it asserts that the speed of light and the fundamental laws of physics are the same for all observers.
What would two observers one stationary and one moving each measure for the speed of light?
The two observers would each measure light to be the same. The speed of light is the same for all observers, regardless of their frames of reference.
How can two different observers measure a different speed for the same object?
It depends on the observer's frame of reference. If both are stationary then an object's speed will be measured to be the same. If one or both are moving at unequal velocities, then the same object will appear to move at a different speed for each observer.
What are einsteins postulates of relativity?
For the Special Theory of Relativity, the basic postulates are:The relativity principle, i.e., laws of nature are the same for observers in different reference frames.The speed of light is the same for different observers.
What happens to the invariant quantities in special relativity?
It depends on what these invariant quantities are. It is not enough to specify that something is invariant, you also need to specify under which operation these quantities do not change (= are invariant). In special relativity there is an operation called a Lorentz transformation which applies the effects of a speed increase, thus applying time dilatation and length contraction. A Lorentz invariant quantity is a quantity which remains the same under this transformation, i.e. it has the same value for every observer in an inertial frame. Examples of such invariants are the lengths of four-vectors, the generalizations of the common 3-dimensional vectors such as those indicating place and momentum. For example the 3d-vector for location (x,y,z) is joined with another quantity for the time dimension into a 4-vector whose length is Lorentz invariant. There are more Lorentz invariant quantities, some of them quite complex.
What is the postulate of general relativity?
The postulate of general relativity states that the laws of physics are the same for all observers, regardless of their motion or gravitational field.
How does the motion of an object appear differently to observers in various frames of reference?
The motion of an object appears differently to observers in various frames of reference due to the principle of relativity, which states that the laws of physics are the same for all observers in uniform motion. This means that the perception of an object's motion can vary depending on the observer's relative position and velocity.
What are the first and second postulates of special relativity?
First Postulate: All the laws of nature are the same in all uniformly moving frames of reference. Second Postulate: The speed of light in empty space will always have the same value regardless of the motion of the source or motion of the observer.
Derived quantities are the?
All other quantities which described in terms of base quantities are called base quantities.
What was Albert Einstein hypothesis?
Albert Einstein's hypothesis was the theory of relativity, which describes how gravity can warp space and time. He proposed that the laws of physics are the same for all non-accelerating observers and that the speed of light in a vacuum is constant for all observers.
What did Einstein special theory of relativity propose?
Einstein's special theory of relativity proposed that the laws of physics are the same for all non-accelerating observers and that the speed of light in a vacuum is constant for all observers. It also introduced the concepts of time dilation, length contraction, and the equivalence of mass and energy (E=mc^2).
Why space-time is taken to be absolute?
its not, it is observed differently by all observers.
