I am wondering ? is it possible that the constants that govern the laws of physics was different during other periods of our universe history ?
mathman said:It is possible. So far all observations concerning this issue have indicated no change, but experimentalists keep looking.
I believe that there is an entire philosophy behind questions which start off with Is it possible... This philosophy is based on the principle that no observation is logically inconsistent. What does that mean in practice? It means that we can't merely say with absolute certainty that certain things are true or false because its conceivable that some day, in some way an observation could prove something to be true where it was postulated to be false in the past. For example: Suppose someone who lived in the days when it was accepted that the Earth was flat. The hypothesis then was the Earth was flat and if one asked "Is the Earth flat?" the one the person who answered in the positive was doing so in agreement with the hypothesis of that day. Not let's consider the question "Is the Earth a sphere" but asked today. The answer is "Yes." But how would one answer "Is it possible that the Earth is flat?" if it was also asked today? I would say not. It's not possible.TeCNoYoTTa said:I am wondering ? is it possible that the constants that govern the laws of physics was different during other periods of our universe history ?
The footnote reads I am in debt to Dr. M. Tausner for this remark.It is perhaps worthwhile noting that particles which travel faster than light d not involve logical inconsistencies. Indeed, no observation can be logically inconsistent.*
Scientists use various methods to study the laws of nature and their constants. These include observational data, mathematical models, and experiments. By analyzing these data, scientists can determine if there have been any changes in the constants over time.
One of the main pieces of evidence supporting the idea that nature laws constants have remained constant is the fact that our current understanding of the laws of nature has been consistent and accurate in predicting and explaining natural phenomena. Additionally, scientists have not observed any significant changes in the constants through various experiments and observations.
One possible explanation for changes in nature laws constants over time could be the influence of external factors, such as cosmic events or shifts in the Earth's environment. Another possibility is that our understanding of these constants may evolve as our scientific knowledge and technology advances.
There are some examples of small changes in nature laws constants over time, such as the gradual decrease in the strength of Earth's magnetic field. However, these changes are relatively small and do not significantly impact our understanding of the laws of nature.
A change in nature laws constants could have significant implications for our understanding of the universe. It could potentially challenge our current theories and models, and require us to revise or develop new ones to explain natural phenomena. It could also lead to a better understanding of the fundamental laws that govern our universe.
