Okay, so a frame of reference is something to be observed, not something to be.
I would say that a frame of reference is a system of coordinates in reference to which the motion of an object may be described.
A frame of reference can be either inertial or non-inertial. For example:
- A ball in a descending lift (elevator) would not appear to be changing its velocity relative to an observer in the lift. Newton 1 is therefore valid so the ball is in an inertial frame of reference.
- A ball on a rotating record player turntable would change its velocity relative to an observer on the turntable. Newton 1 is therefore not valid so the ball is in a non-inertial frame of reference.

...after ( t+delta) the universe spatial dimentions and coordinate are going to change . For local use it can be used .
Yes, when discussing frames of reference, it's simpler to deal with Newtonian coordinates (i.e. "local use") rather than spacetime coordinates!
Wiki has a nice entry in IFOR. Here is a bit from near the end which in simple language says if a set of objects are moving together they will form an IFOR (think about Einstein’s elevator thought experiment). If all the bodies experience the same force, they will remain in the same IFOR.
Similarly, if one of the objects has an accelerating force applied to it for a time, after that force is removed, it will not be in the same IFOR as the other objects it was prior to the application of the force (I’m not counting objects bouncing off the walls of a falling elevator here btw). You could also argue this must be the case because of entropy - energy has been expended, and the overall systems entropy has increased.

The Wikipedia entry correctly says that any reference frame that is stationary or moving at a constant velocity relative to an inertial frame will also be an inertial frame.
Regarding a lift (elevator) in its normal mode of opertion: It will be an inertial frame of reference when it has a constant velocity going up or down, but becomes a non-inertial frame of reference when it accelerates.
Regarding a freely falling lift: Einstein realised that its interior would constitute an inertial frame. Because every object within it would be falling at the same rate they would effectively appear as if they were at rest in an empty region of space. The motion of an object could be referenced to a freely falling frame at that location - an idea superior to Newton's idea of referencing motion to an imaginary inertial frame that he called "absolute space".
Einstein called his idea the "equivalence principle".
Learning all the time! 😎
What was Einstein's ultimate goal in his quest for knolwledge?some thoughts to think upon
from Albert Einstein:
“I didn't arrive at my understanding of the fundamental laws of the universe through my rational mind.”
“Concerning matter, we have been all wrong. What we have called matter is energy, whose vibration has been so lowered as to be perceptible to the senses. Matter is spirit reduced to point of visibility. There is no matter.”
"Time and space are not conditions in which we live, but modes by which we think.
Physical concepts are free creations of the human mind, and are not, however it may seem, determined by the external world."
“Time does not exist – we invented it. Time is what the clock says. The distinction between the past, present and future is only a stubbornly persistent illusion.”
“I think 99 times and find nothing. I stop thinking, swim in silence, and the truth comes to me."
"The intellect has little to do on the road to discovery. There comes a leap in consciousness, call it intuition or what you will, the solution comes to you and you don’t know how or why.”
"A human being experiences himself, his thoughts and feelings as something separated from the rest, a kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty."
"Our separation from each other is an optical illusion."
“When something vibrates, the electrons of the entire universe resonate with it. Everything is connected. The greatest tragedy of human existence is the illusion of separateness.”
“Reality is merely an illusion, albeit a very persistent one.”
“We are souls dressed up in sacred biochemical garments and our bodies are the instruments through which our souls play their music.”
“When you examine the lives of the most influential people who have ever walked among us, you discover one thread that winds through them all. They have been aligned first with their spiritual nature and only then with their physical selves.”
“The true value of a human being can be found in the degree to which he has attained liberation from the self.”
“The ancients knew something, which we seem to have forgotten.”
“The more I learn of physics, the more I am drawn to metaphysics.”
“One thing I have learned in a long life: that all our science, measured against reality, is primitive and childlike. We still do not know one thousandth of one percent of what nature has revealed to us. It is entirely possible that behind the perception of our senses, worlds are hidden of which we are unaware.”
“I’m not an atheist. The problem involved is too vast for our limited minds. We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written those books.”
"The common idea that I am an atheist is based on a big mistake. Anyone who interprets my scientific theories this way, did not understand them."
"Everything is determined, every beginning and ending, by forces over which we have no control. It is determined for the insect, as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper."
and so--
0 What is all encompassing can have no opposite.
1 Before the beginning was a Cause and the entire purpose of the Cause was the creation of effect.
2 In the beginning and forever is the decision and the decision is TO BE.
3 The first action of beingness is to assume a viewpoint.
4 The second action of beingness is to extend from the viewpoint, points to view, which are dimension points.
5 Thus there is space created, for the definition of space is: viewpoint of dimension. And the purpose of a dimension point is space and a point of view.
6 The action of a dimension point is reaching and withdrawing.
7 And from the viewpoint to the dimension points there are connection and interchange. Thus new dimension points are made. Thus there is communication.
8 And thus there is light.
9 And thus there is energy.
10 And thus there is life.
11 But there are other viewpoints and these viewpoints outthrust points to view. And there comes about an interchange amongst viewpoints; but the interchange is never otherwise than in terms of exchanging dimension points.
12 The dimension point can be moved by the viewpoint, for the viewpoint, in addition to creative ability and consideration, possesses volition and potential independence of action; and the viewpoint, viewing dimension points, can change in relation to its own or other dimension points or viewpoints. Thus comes about all the fundamentals there are to motion.
13 The dimension points are each and every one, whether large or small, solid. And they are solid solely because the viewpoints say they are solid.
14 Many dimension points combine into larger gases, fluids or solids. Thus there is matter. But the most valued point is admiration, and admiration is so strong its absence alone permits persistence.
15 The dimension point can be different from other dimension points and thus can possess an individual quality. And many dimension points can possess a similar quality, and others can possess a similar quality unto themselves. Thus comes about the quality of classes of matter.
16 The viewpoint can combine dimension points into forms and the forms can be simple or complex and can be at different distances from the viewpoints and so there can be combinations of form. And the forms are capable of motion and the viewpoints are capable of motion and so there can be motion of forms.
17 And the opinion of the viewpoint regulates the consideration of the forms, their stillness or their motion, and these considerations consist of assignment of beauty or ugliness to the forms and these considerations alone are art.
18 It is the opinions of the viewpoints that some of these forms should endure. Thus there is survival.
19 And the viewpoint can never perish; but the form can perish.
20 And the many viewpoints, interacting, become dependent upon one another’s forms and do not choose to distinguish completely the ownership of dimension points and so comes about a dependency upon the dimension points and upon the other viewpoints.
21 From this comes a consistency of viewpoint of the interaction of dimension points and this, regulated, is time.
22 And there are universes.
23 The universes, then, are three in number: the universe created by one viewpoint, the universe created by every other viewpoint, the universe created by the mutual action of viewpoints which is agreed to be upheld – the physical universe.
24 And the viewpoints are never seen. And the viewpoints consider more and more that the dimension points are valuable. And the viewpoints try to become the anchor points and forget that they can create more points and space and forms. Thus comes about scarcity. And the dimension points can perish and so the viewpoints assume that they, too, can perish.
25 Thus comes about death.
26 The manifestations of pleasure and pain, of thought, emotion and effort, of thinking, of sensation, of affinity, reality, communication, of behavior and being are thus derived and the riddles of our universe are apparently contained and answered herein.
27 There is beingness, but man believes there is only becomingness.
28 The resolution of any problem posed here by is the establishment of view-points and dimension points, the betterment of condition and concourse amongst dimension points, and, thereby, viewpoints, and the remedy of abundance or scarcity in all things, pleasant or ugly, by the rehabilitation of the ability of the viewpoint to assume points of view and create and uncreate, neglect, start, change and stop dimension points of any kind at the determinism of the viewpoint. Certainty in all three universes must be regained, for certainty, not data, is knowledge.
29 In the opinion of the viewpoint, any beingness, any thing, is better than no thing, any effect is better than no effect, any universe better than no universe, any particle better than no particle, but the particle of admiration is best of all.
30 And above these things there might be speculation only. And below these things there is the playing of the game. But these things which are written here man can experience and know. And some may care to teach these things and some may care to use them to assist those in distress and some may desire to employ them to make individuals and organizations more able and so give to Earth a culture of which we can be proud.
-- Considerations take rank over the mechanics of space, energy, and time; By this it is meant that an idea or opinion is, fundamentally, superior to space, energy, and time, or organizations of form, since it is conceived that space, energy, and time are themselves broadly agreed-upon considerations. That so many minds agree brings about Reality in the form of space, energy and time. These mechanics, then, of space, energy, and time are the product of agreed-upon considerations mutually held by life.
The aspect of existence when viewed from the level of Man, however, is a reverse of the greater truth above, for Man works on the secondary opinion that mechanics are real, and that his own personal considerations are less important than space, energy, and time. This is an inversion. These mechanics of space, energy, and time, the forms, objects and combinations thereof, have taken such precedence in Man that they have become more important than considerations as such, and so his ability is overpowered and he is unable to act freely in the framework of mechanics. Man, therefore, has an inverted view.
Whereas, considerations such as those he daily makes are the actual source of space, energy, and time and forms, Man is operating so as not to alter his basic considerations; he therefore invalidates himself by supposing another determinism of space, energy, time, and form. Although he is part of that which created these, he gives them such strength and validity that his own considerations thereafter must fall subordinate to space, energy, time and form, and so he cannot alter the Universe in which he dwells.
The freedom of an individual depends upon that individual's freedom to alter his considerations of space, energy, time, and forms of life and his roles in it. If he cannot change his mind about these, he is then fixed and enslaved amidst barriers such as those of the physical universe, and barriers of his own creation. Man thus is seen to be enslaved by barriers of his own creation. He creates these barriers himself, or by agreeing with things which hold these barriers to be actual.
Human body is nothing but group of microorganisms working together to survive . Consciousness is a very overrated word . In reality it's just an illusion . We being conscious can not be able to hurt ourself . You ask why . Because our brain works for them microorganisms too who we are going to hurt . And will not allow it . And yes I don't think we have souls . We tricks ourselves on behalf of our body to think we are conscious and have souls . Human body is so perfect it's tricks itself 😂
So what exactly is this "concsious 'we'"?We being conscious
Being aware to be.So what exactly is this "concsious 'we'"?
"To be or not to be, that is the question".
Francis Bacon.
"2B or not 2B?".
That is the question Einstein asked of himself when choosing the pencil with which to write his theories. 😀

An IFOR is generally defined as any object not undergoing acceleration, that is coasting along, and experiencing no external forces.
Forgive me for returning to this, Bonsai, but your implication that an inertial frame of reference is a propery of an object still bugs me! 🐛
It appears to me that your unreferenced definition confuses inertial frame with inertia.
- Inertia is the property an object which causes it to remain stationary or move at a steady speed in a straight line.
- An inertial frame is a frame of reference in which the above condition of motion holds.
I now feel happier, relatively speaking! 😉

Some suspect that Bacon wrote Shakespeare's work.

More probably, Bacon wrote the scrambled version of Hamlet - Omelette!
There is a controversial theory claiming that William Shakespeare was actually Francis Bacon.That was Shakespeare, no?
I happened to had an English teacher an advocate of this. He wrote books made researchs, involved his students about hidden signs proving that.
He made so much trouble that the Britts could not stand it anymore, banned him from England, gave him the persona non grata status.
Needless to say that in the English classroom we had great fun and all will ever remember.
