Is the twin paradox possible if the space twin was in an inertial frames of reference?
JJ7766
No, if both persons are in inertial frames of reference the situation is completely symmetric so the 'paradox' does not occur. Also note that it is not really a paradox because general relativity has a conclusive answer to what happens to the twins.
It is; however, not possible to set up a twin paradox-like situation with neither twin never leaving an inertial frame. This is because if they want to move apart, and come back again, they need to accelerate somehow, and the act of acceleration causes you to leave an inertial frame.

Why newton's laws are not valid in non inertial frame of reference?
newtons laws are always valid in non inertial frames
Is newton's third law valid universally?
Only in inertial reference frames.
What does the theory of special relativity say about the equivalence of different frames of reference?
It says that the speed of light in a vacuum measured in any inertial frame of reference is equivalent to the speed of light in a vacuum measured in any other inertial frame of reference.
Does the speed of light is same in all inertial reference frames?
Yes, as long as the light is passing through vacuum.
Why an object falls of placed in air unsupported if a room is an inertial frame of reference. this means the room is moving in the upward direction how?
If the object is falling down, it is accelerating. "Inertial frames of reference" do not include acceleration, so the falling object can't be considered an inertial frame of reference, according to the Special Theory of Relativity. However, the General Theory or Relativity explores additional complications due to gravity. In any case, if you wish, you can use the object accelerating downward as a reference frame (just don't call it "inertial"); in this case, obviously the room is accelerating upward, compared to the falling object. It all depends what object you choose as your reference frame.
When was Frames of Reference created?
Frames of Reference was created in 1960.
What are lorentz transformatios in non-inertial frame?
It's unfortunate that this system does not allow mathematical notation, so these have to be at least partly spelled out. Some definitions: t0 refers to time interval as measured in an inertial frame t refers to the relative non-inertial time measurement m0 and m for mass, and L0 and L for length (along the direction of travel) follow the same pattern t = t0/the square root of [1-(v/c)2] m = m0/the square root of [1-(v/c)2] L = L0{the square root of [1-(v/c)2]} The lorentz transformations, by definition, compare the relationship between non-inertial frames and their designated inertial reference frames.

What is an intertial frame of reference?
Assuming you mean "inertial" frame of reference... it is any point of observation from which other objects appear to be still or in motion relative to you. For example... On an airplane flying at 35,000 feet. All the other passengers appear to you to be sitting in their seats or walking down the aisle at a leisurely pace... If you tossed a ball in the air, it would appear to go straight up and fall back into your hand... To someone on the ground, you and all your fellow passengers seem to be hurtling thru the sky at 500 mph. And the path the ball follows is not straight up or down. You and your fellow passengers share the same inertial frame of reference. In a similar sense, the earth under your feet appears to be still and all the objects seem to move or not move in relation to the still earth. In fact the earth is spinning... beyond that it is revolving around the sun, beyond that the entire solar system is moving in a galaxy that is, itself spinning, and the entire galaxy is also moving thru a universe that is expanding... Each of these are other inertial frames of reference. Einstein's theory of relativity states that none of these frames of reference is preferred... and that all observations, including those relating to time, dimension and speed, are entirely relative to one's inertial frame of reference. Thus different observers in different frames of reference perceive things differently. because even time varies with frame of reference, this renders such concepts as simultaneity specious. If time itself passes at different rates for different observers, then no two events can actually be said to happen at the same time.
Is velocity constant?
Constant velocity is known as uniform velocity, which is achieved when the net force (or resultant force) of a body is zero i.e. there is no external forces causing the body to accelerate or decelerate.To look at it from a Calculus dimension:If the derivative of the position vector with respect to time = 0 in an inertial reference frame.i.e. it is moving with constant speed in a direction in an inertial reference frame.I prefer the following statement which is equivalent to the above:If the second derivitive (i.e. acceleration) of the position vector is 0 in any one inertial frame, then it is 0 in all inertial frames and there exists at least oneinertial frame in which the first derivitive (i.e. velocity) of the position vector is 0.In short:Neither speed nor direction of motion changes.
Can movement only be measured with reference that is assumed to be fixed in pace?
No, Einstein proved that all inertial frames are equally valid references. You don't have to assume it's "fixed in place" or even know exactly how it's moving relative to any other frame as long as you know how the measured object is moving relative to the chosen reference frame.
