In summary, the top speed of information is c. In theory, there is no limit to simultaneous events in the universe, but the concept of simultaneity can differ between observers. Simultaneity does not necessarily imply causality. In relativity, if event A happens before B in one frame, it will happen before B in all frames. Ultimately, the top speed of information, c, allows for the possibility of simultaneous events occurring in the universe.

The top speed of information is c.

1. Then is it correct to say that theoretically there cannot be any simultaneous happenings in the universe (like theories depend on causality)?

2. Is it then correct to deduce that only one particle in the universe is at changing state at a given time (Planck time?)?

3. So - theoretically - no single particle can even move and rotate simultaneously... ?

4. Or can not move "along more than one axis" at a time (Planck time?)... ?

5. Again I'm confused... :D ?

Your first assumption is incorrect.
There's no objection to simultaneous events, it's just that "simultaneous" has different meanings to different obervers.
"Simultaneous" just means: light signals from these events reach my clock at the same instant of time.
Note that simultaneity is something different from causality. "Even" in relativity, if event A happened before B in some arbitrary frame, then there will be no equivalent frame in which B takes place after A).

after A).

... and they all lived happily ever after, or, originally, "happily until their deaths".

Sorry - embarrassed - once again...
 

1. What is the speed of light (c)?

The speed of light, denoted by the letter c, is a universal physical constant that represents the speed at which light travels in a vacuum. It is approximately 299,792,458 meters per second.

2. How does the speed of light affect physical phenomena?

The speed of light plays a crucial role in many physical phenomena, including the behavior of particles, the properties of electromagnetic waves, and the concept of space and time. Understanding the speed of light is essential for exploring and explaining these phenomena.

3. Can anything travel faster than the speed of light?

According to Einstein's theory of relativity, the speed of light is the ultimate speed limit in the universe. Nothing can travel faster than the speed of light, as it would require an infinite amount of energy.

4. How do scientists study physical phenomena at the speed of light?

Scientists use a variety of tools and techniques to explore physical phenomena at the speed of light. These include particle accelerators, high-speed cameras, and advanced simulations and calculations. They also rely on the principles of relativity and quantum mechanics to better understand these phenomena.

5. Why is studying physical phenomena at the speed of light important?

Studying physical phenomena at the speed of light allows scientists to better understand the fundamental laws and principles that govern our universe. It also has practical applications, such as in the development of new technologies and materials, and in advancing our understanding of the origins of the universe.
