A particle that moves a certain distance in the gravitational field of
a small mass,changes its weight as it moves.But if that particle had
been stationary relative to the small mass, and the gravitational
field had
changed its strength with time, in such a way that the weight of the
stationary particle, from one moment to the next, was exactly the same
as the weight of the moving particle from one moment to the next,a
clock close to the particle at all instants of time, would measure
the same time elapsed in both cases.If I looked at the time on the
clock, I wouldn't know if the particle had been moving or
stationary.If the electric field and other fields behaved in this
manner, would I be able to distinguish between a movement
through space in the presence of non-oscillating fields and a
movement through time in the presence of oscillating fields?

The ideas are fundamental, the language is primary. Particals and clocks, weight instead of mass, no mention of field or symmetry. How can we talk with words that have not been carefully defined?

The short answer is that movement, that is change, requires description involving some of at least three spatial and one time dimension. No movement can take place in space devoid of time, and if there were only time, no space, where would change take place? So we must speak of change in terms that involve both space and time, at least one dimension of space and one dimension of time, like a string that is only vibrateing by compression waves along its own lenth, and not in any secondary lateral sense.

Of course no real string vibrates in such a limited fashion. But for the sake of greater understanding we may refer to such a linear motion, given the existence of one dimension in time and one in space. We can even draw pictures of such an idea, altho most images we commonly look at are of two spatial dimensions, with variations in color and texture to suggest real objects, like buildings and trees. And if we choose three dimensions in space and one in time we can talk about complicated motions like orbits and objects in free-fall and what it is we mean by a frame of reference, and all of this is already described by great minds who have given us much understanding with beauty and elegance.

When you are making descriptions, you get to choose which dimensions and which operations you intend to describe. It is a sort of game which has its own rules that have been laid down in history, and we need to learn those rules in order to play, that is to talk to each other, about what is going on with weight and motion of various kinds. It seems you are kurious, but how far curiosity takes you is up to you.

Good hunting, and welcome to the quest.

Both movement through space and movement through time have distinct characteristics and can be differentiated from each other. In the given scenario, the particle's weight changing as it moves through the gravitational field indicates movement through space. On the other hand, the changing strength of the gravitational field over time would suggest movement through time.

If the electric and other fields behaved in a way that the weight of the stationary particle remained the same as the moving particle at each moment, it would be difficult to distinguish between movement through space and movement through time. However, there are other factors that can help differentiate between the two.

For example, in movement through space, there is a displacement of the object in physical space, whereas in movement through time, there is a change in the object's position in time. Additionally, movement through space can also be observed through changes in velocity and acceleration, while movement through time can be observed through changes in frequency and duration.

Furthermore, the concept of relativity also plays a crucial role in differentiating between movement through space and time. According to Einstein's theory of relativity, time and space are intertwined and cannot be separated. Therefore, any movement through space will also involve a change in time and vice versa.

In conclusion, while it may be difficult to distinguish between movement through space and time in certain scenarios, there are distinct characteristics and factors that can help differentiate between the two. Additionally, the concept of relativity also plays a significant role in understanding the relationship between movement through space and time.
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
According to the General Theory of Relativity, time does not pass on a black hole, which means that processes they don't work either. As the object becomes heavier, the speed of matter falling on it for an observer on Earth will first increase, and then slow down, due to the effect of time dilation. And then it will stop altogether. As a result, we will not get a black hole, since the critical mass will not be reached. Although the object will continue to attract matter, it will not be a...
