Can baseballs truly synchronize clocks ?

• Edd
In summary, Einstein's theory of relativity predicts that the synchronization achieved with very fast particles or accurately tossed lower-speed particles is equivalent to the synchronization achieved with light. This means that while it is possible to synchronize clocks with baseballs, it will not result in an absolute synchronization but rather a relative one.
Edd
Einstein defined truly or absolutely synchronous clocks as follows:
"The simultaneity of two definite events with reference to one inertial system involves
the simultaneity of these events in reference to all inertial systems. This is what is meant
when we say that the time of classical mechanics is absolute. According to the special
theory of relativity it is otherwise."

Suppose we have a double-armed baseball tossing machine that can toss two baseballs
equally forcefully in opposite directions. If this machine is placed midway between two
unstarted-but-set-to-start-on-zero clocks, it seems to me that a couple of machine-tossed
baseballs would start the clocks at absolutely the same time, thereby absolutely synching them.

Is there any physical reason why this won't happen? Just wondering….

Relativity predicts that the baseball tossing mechanism will provide the same synchronization as light-tossing.

It will be hard to toss baseballs accurately enough to get experimental verification. You can improve accuracy by tossing the baseballs faster and faster. In fact, if you use a particle accelerator to accelerate particles as fast as you can, the particles will be moving essentially at the speed of light - very fast baseballs, in essence.

The idea is that all fair synchronization, whether it is based on very fast particles, or very accurately tossed lower-speed particles, or light itself, will be equivalent.

Relativity predicts tha tthe speed of light being the same for all observers and the same in all directions , i.e. isotropy, and also that that limiting speed, c matches the limiting speed of how fast you can toss a baseball and/or elementary particle. A consequence of relativity is that you get different synchronization results for different frames of reference. See "the relativity of simultaneity" , and/or "Einstein's train" there's been a number of recent threads on the concept.

So the short answer is that you can synchronize clocks with baseballs, but you won't thereby achieve an "absolute" synchronization, you'll get the same relative synchronization that you get with light.

What is the concept behind the synchronization of clocks using baseballs?

The concept behind the synchronization of clocks using baseballs is based on the idea that the vibrations of the baseballs can be used to keep time. This is because the vibrations of the baseballs are consistent and can be measured accurately.

How does the synchronization of clocks using baseballs work?

The synchronization of clocks using baseballs works by placing a group of baseballs on a flat surface and allowing them to vibrate. The vibrations of the baseballs are then used to set the time on a clock, making it synchronized with the vibrations of the baseballs.

Is it scientifically proven that baseballs can accurately synchronize clocks?

There have been studies and experiments conducted to test the accuracy of using baseballs to synchronize clocks. While the results have shown promising accuracy, it is still a relatively new concept and further research is needed to fully confirm its effectiveness.

What are the potential benefits of using baseballs to synchronize clocks?

The potential benefits of using baseballs to synchronize clocks include the ability to keep time accurately in places where traditional timekeeping methods may not be available, such as in remote areas or during power outages. It also offers an alternative method of timekeeping that does not require electricity or batteries.

Are there any limitations to using baseballs to synchronize clocks?

One limitation of using baseballs to synchronize clocks is that it relies on the consistency of the vibrations of the baseballs. Any external factors, such as changes in temperature or humidity, may affect the accuracy of the synchronization. Additionally, it may not be as precise as other timekeeping methods and may require frequent adjustments.
