Parallel and Serial Events

In summary, Bridgman commented on Einstein's theories of special and general relativity. He said that more analyses should be given to the events of the theories rather than analytical attacks on the coordinate system used in specifying the physical events found in the theories.

The Nobel Laureate P.W. Bridgman commented on Einstein’s theories of special and general relativity. He said that more analyses should be given to the events of the theories rather than analytical attacks on the coordinate system used in specifying the physical events found in the theories.

Generally, events are analyzed by the use of three spatial coordinates and one time coordinate. In this discussion, events are only analyzed by the use of one time coordinate.
This method can simplify the analysis tremendously. The time coordinate is assumed to take a form of geometry similar to physical space. This is the extraction of time from the spacetime of relativity and keeping the spatial parts hidden away. In this way, one can define time as a line embedded in the following three geometries: Euclidean (planar), Riemannian (spherical) and Lobatchevskian (hyperbolic).

By parallel timed events, it is to mean that simultaneity can be defined between one event in one timeline and another event in the other timeline. But for an observer in one timeline, he or she is not capable of knowing whether these two events are simultaneous. There is no information send by photons from one to the other. These events can only be assumed to be simultaneous. And that is all one can do. Each photon of each timeline travels along each line and no reason to jump to the other line. Each line contains its own reality.

By serial events, it is to mean that simultaneity has no meaning. All events follow or lead other events. These successions of events gave true meaning to the word “timeline.”

In Euclidean geometry, two parallel timelines can be constructed. The simultaneity of two parallel events is the end points of the perpendicular distance between the lines. In theory, there are an infinite number of simultaneous events. But the following assumptions must be made that (1) the time tick-marks are the same for the lines and (2) that the line are infinitely extended in both directions. The events along one timeline are all serial events.

In Riemannian geometry, parallel events cannot be constructed. Hence simultaneity has no meaning. All events are serial. But a zero time can be defined as located at one of the poles. The other pole will be the end of time.

In Lobatchevskian geometry, many infinitely extended parallel timelines can be constructed. Each of these timeline contains serial events. But there is only one occurrence of simultaneity for these parallel events. And this happens at the same time.

Parallel timed Events?

.

In other words do you mean that Time travel events might
be happening at all times but we cannot tell such actions
are taking place as we are in another parallel universe ? :rofl:

Sorry for this belated reply. I was preoccupied with the theory development site.

The other timeline I am talking is the one traveled by all the antimatter. And, yes, in a sense, this can be thought of as in another parallel universe. But the vacuum is the connecting link between our universe and this antiuniverse.

Antimatter exists in the same time and universe as ordinary matter does. In spite of confusing popular "explanations" of the mathematics of antimatter that imply magical properties for antiparticles, they are not mysterious or contradictory. Quantum field theory would be incomplete if it didn't cover both kinds of particles, and familiar physical facts like radioactivity rely on antiparticles. Among the other particles emitted by the weak interaction is an antineutrino.

I think I read somewhere (Feynman?) that an anti-electron or positron can be thought of as an ordinary electron traveling backward in time? If I can find a reference I'll try to return and post it here.

"Can be thought of" is precisely the problem I was talking about. Feynman knew what he meant, and other physicists know what he meant. The mathematics describing a positron (anti-electron) can be made to be identical to the math describing the electron if you replace the t (for time) by -t. This is an interesting and valuable duality, but time travel it is not.

Feynmann and his former thesis advisor Wheeler liked to play around with wild and crazy ideas. Feymann's time reversal idea was part of what led him to his very valuable sum over histories, or path integral method. But although he discussed a lot of future capabilities (such as nanotechnology), he never wrote about macroscopic time travel.

Travel by time, it to use time power.
The time system is power enough first.

Can you please explain this a little bit more? Thanks.
 

1. What is the difference between parallel and serial events?

Parallel events occur simultaneously, while serial events occur one after the other.

2. Can parallel and serial events happen at the same time?

Yes, it is possible for parallel and serial events to happen at the same time. This is known as a combination of parallel and serial events.

3. How do parallel and serial events affect data processing?

Parallel events enable multiple tasks to be processed at the same time, increasing efficiency. Serial events, on the other hand, process tasks one at a time, which can lead to slower processing times.

4. Are there any real-life examples of parallel and serial events?

Yes, there are many real-life examples of parallel and serial events. For example, a computer can have multiple programs running at the same time (parallel), while it can also process tasks such as printing documents one at a time (serial).

5. How do parallel and serial events impact hardware design?

Parallel events require hardware to have multiple processing units, while serial events only require a single processing unit. This means that hardware for parallel events can be more complex and expensive to design and manufacture.
