Can Light Be the Perfect Reference Frame to Solve Problems of Reference Frames?

In summary, the conversation discusses the problem of perfect reference frames and how the expansion of the universe affects it. The concept of light as the perfect reference frame is introduced and its potential use in solving the problem is questioned. The understanding of a reference frame is also clarified.

We have a problem of perfect reference frames( according what we are taught in school)
If universe is expanding, the so called fixed stars are also moving.
According to the special relativity, the speed of light is constant in every reference frame,
So if we let light as the perfect reference frame, will not be the problem of reference frames solved?
Answers are welcomed, Thanks in advanced

What do you mean with "light as the perfect reference frame"? How do you plan to use light to describe any reference frame?
Which "problem of reference frames" do you mean?

Let's go back a bit. Do you know what a reference frame is? It sounds like you might not.

I think the frame of reference is a set of points from which we find out the position, and by that relative speed.
And my point is that if we take the relative speed of anything with reference of light,instead of fixed stars,than it would be perfect because light never accelerates or decelerates. As universe's expansion is speeding, fixed stars are also accelerating so if we define any speed in reference to fixed stars, it would be wrong, but as light do not accelerates can't we define all velocities with respect to light?

A reference frame allows to give a position and velocity for an object - as seen by this frame. It is not "the position/velocity of the object" (that does not exist).

The relative speed of anything relative to light is the speed of light (as seen by the object) or depends on the reference frame (if you just subtract both velocities). This is a problem even if you ignore expansion of the universe, or stars, or any other objects.
 

What is a perfect reference frame?

A perfect reference frame is an imaginary coordinate system that is used to describe the motion of objects in physics. It is a frame of reference that is stationary and does not experience any external forces, making it ideal for measuring the motion of other objects.

Why is a perfect reference frame important in physics?

A perfect reference frame is important in physics because it allows us to accurately describe and understand the motion of objects. By using a frame of reference that is not affected by external forces, we can isolate and analyze the motion of objects in a more precise manner.

How is a perfect reference frame different from a non-inertial reference frame?

A perfect reference frame is different from a non-inertial reference frame in that it does not experience any external forces, while a non-inertial reference frame does. This means that objects in a non-inertial reference frame will appear to have an acceleration, while objects in a perfect reference frame will appear to have a constant velocity.

Can a perfect reference frame exist in the real world?

No, a perfect reference frame is a theoretical concept used in physics to make calculations and predictions. In reality, it is impossible to have a frame of reference that is completely unaffected by external forces. However, by using a perfect reference frame, we can make accurate approximations and predictions about the motion of objects.

How is a perfect reference frame determined?

A perfect reference frame is determined by assuming that it exists and does not experience any external forces. It is a simplified version of a frame of reference in which only the motion of the object being studied is taken into account, while all other factors are ignored.
