How many times are you going to reiterate the same dozen pseudo-sciencey points?
How many times are you going to reiterate the same dozen pseudo-sciencey points?
You post a summary about every dozen posts.That's a summary that I've said so far.
2- Does time exist?
Yes, time exists because it is a measurable quantity and affects all of reality.
3- Can we perceive time?
No, we only perceive changes or becoming. The intervals are subperceptible.
2 and 3 contradict each other. If we only perceive change, then how is anything but change a measurable quantity? We measure change, not time. Time is an abstraction of measurements of relative rates of change.
10 questions about time
These questions are answered by Philochrony.
1- What is time?
Time is the periodic process that we use to measure the duration of things.
Nope, you forgot plasma.Just as matter manifests itself in three states: solid, liquid, and gaseous
As opposed to what other kind of time?With the development of Mathematics, abstract time arises.
No. That's actually the thing. The equations don't describe time as flowing anywhere.According to the equations, time flows from the past to the future and from the future to the past.
No. Hence we have the idea of time reversal symmetry in physics.For equations it is the same that time is irreversible.
What is "natural time"? The time we experience? Hawking called that "psychological time".But natural time only flows in one direction: from the past to the future.
That's circular and therefore useless. The law describes time, but time is the law, which the law describes, but the law is time and time is the law. Word salad.This is the law of the arrow of time. The arrow of time is the law itself.
Hawking, in A brief history of time, described several arrows of time. Two of those were what he called the thermodynamic arrow and the psychological arrow.Entropy is a law of Thermodynamics, and is an application of the law of the arrow of time.
You mean, the order of events. But the arrows don't really "govern" the order. They just describe the direction in which events are observed to happen: from "past" to "future".The events of reality are governed by the law of the time arrow.
An empty, useless definition, like all the rest of "philochrony". This is pseudoscience writ large.Let's remember the definition of time given by Philochrony: time is the periodic evolution that we use to measure the duration of things and determine when events occur.
You're begging the question by assuming that the changes are irreversible, without doing anything to establish them as such.While duration is the continuous succession of irreversible changes that go from the past (before) to the future (after) passing through the present.
As Asexperia said: ↑
1- With the development of Mathematics, abstract time arises.
Unlike what other kind of time?
Asexperia: of real time, natural
2- According to the equations, time flows from the past to the future and from the future to the past.
That's actually the question. The equations do not describe time as something that flows anywhere.
Asexperia: Even worse. Time in equations is a dead thing.
3- For the equations it is the same that time is irreversible.
No. Hence we have the idea of time reversal symmetry in physics.
Asexperia: But if it doesn't flow, asymmetry is no use.
4- But natural time only flows in one direction: from the past to the future.
What is "natural time"? The time we live? Hawking called this "psychological time."
Asexperia: Both abstract time and psychological time are merely subjective.
Natural time is the time of reality.
5- This is the law of the arrow of time. The arrow of time is the law itself.
That is circular and therefore useless. The law describes the time, but the time is the law, which the law describes, but the law is the time and the time is the law. Word salad.
Asexperia: The arrow is the direction in which time flows. You created the salad because you doesn't have argument.
6- Entropy is a law of thermodynamics, and is an application of the law of the arrow of time.
Hawking, in A Brief History of Time, described several arrows of time. Two of them were what he called the thermodynamic arrow and the psychological arrow.
Asexperia: The thermodynamic arrow is objective and the psychological arrow is subjective.
You have causality backwards. The second law of thermodynamics is not an "application" of the arrow of time. Hawking said, on the contrary, that the 2nd law is what establishes the direction of the thermodynamic arrow of time.
Asexperia: It is the same as what I propose.
7- Let's remember the definition of time given by Filocronía: time is the periodic evolution that we use to measure the duration of things and determine when events occur.
An empty and useless definition, like all the rest of the "philochrony". This is full-fledged pseudoscience.
Asexperia: No, Philochrony is a science not understood by some.
8- While duration is the continuous succession of irreversible changes that go from the past (before) to the future (after) passing through the present.
You are asking the question by assuming that the changes are irreversible, without doing anything to establish them as such.
Asexperia: I gave several examples of irreversible changes.
HahahahahaThat's great. Now you're merely quoting yourself.
A science makes testable predictions and is falsifiable. Philochrony has neither of those features, as far as I can tell.No, Philochrony is a science not understood by some.

If it is science all of them.Enlighten me, what's a science that makes testable predictions and is falsifiable?
I'll give you an example from the laws of thermodynamics. The Second Law of thermodynamics says that heat will flow spontaneously from one system to another when they are placed in contact, and that the heat flow is always from the hotter object to the colder object, and that the heat flow continues until the two objects reach the same temperature.Enlighten me, what's a science that makes testable predictions and is falsifiable?
Being that this it is now 4 years and 437 posts of the same silliness expressed about 400 different times, I'm gonna say no.Does that help?
I'll give you an example from the laws of thermodynamics. The Second Law of thermodynamics says that heat will flow spontaneously from one system to another when they are placed in contact, and that the heat flow is always from the hotter object to the colder object, and that the heat flow continues until the two objects reach the same temperature.
Here's a test: heat up a rod of iron in a blast furnace or forge. Then, dunk the iron rod into a bucket filled with cold water. The prediction from the second law of thermodynamics is that the iron rod will cool down and the water in the bucket will heat up (due to the heat transfer between the rod and the water), until eventually the rod and the water are both at the same temperature.
This is a testable prediction since we can use thermometers to measure the temperatures of the rod and the water continuously, before and after the rod is placed in contact with the water.
The second law would be falsified if this experiment showed that the rod's temperature increased after it was placed in the cold water, or if the cold water got colder after the rod was placed in it, or if no heat exchange occurred and both the rod and the water stayed at their original temperatures.
So, you can see that the second law makes a simple, testable prediction and that the law could, in principle, be falsified in several different ways.
Does that help?
No. In the example, the theory allows us to make a specified, testable prediction about what will occur if we carry out a specific experiment. The test is the process of actually carrying out the experiment and comparing the results to the prediction. If the theory made an incorrect prediction, then it has been falsified by the experiment (or there's some problem with the experiment, or a confounding factor separate from the theory being tested, which we didn't control for). If the theory made a correct prediction, then our confidence in the truth (or usefulness) of the theory should rise in proportion to the specificity of the prediction and the stringency of the test.Yes, thanks. But that could be more a testable conclusion than a prediction.
