What time is it... Really?


Recommended Posts

The units of time (hours, minutes, seconds, etc.) are a human invention, but time itself is a fundamental aspect of the universe.

Time is a completely human invention, there's nothing fundamental about it. What people think of as a 'fundamental aspect of the universe' is actually entropy

True. But the original question is still invalid, because putting a specific label on the amount of time passed since event x is always introducing an artificial, meaningless element.

To make up for this lost time, we of course have added the idea of a "leap year" in which every 4 years we add an extra day. But if you do the math, that "leap year" does not fully account for every last second & as time continues to add... Those seconds become minutes, hours, days.... And of course, what about all the years before the calender included a "leap year"....

Err - do you not know why we have a leap year?

We say there are 365 days in the year and by this we mean that it takes the earth 365 days to make its annual trip around the sun. Actually, though, it takes the earth 365-1/4 days to make this trip. This means that every year we gain one-fourth of a day and every four years we gain one full day.

If we did nothing about this, our calendar would move backward one full day every four years relative to our seasons. To keep this from happening, we capture the extra day every four years and put it into our smallest month, February.

Something like that.

As I was walking down the street one day

A man came up to me and asked me what

The time was that was on my watch, yeah...And I said

(I don't) Does anybody really know what time it is

(Care) Does anybody really care (about time)

If so I can't imagine why (Oh no, no)

We've all got time enough to cry

And I was walking down the street one day

A pretty lady looked at me

And said her diamond watch had stopped cold dead...And I said

(I don't) Does anybody really know what time it is

(Care) Does anybody really care (about time)

If so I can't imagine why (Oh no, no)

We've all got time enough to cry

And I was walking down the street one day

Being pushed and shoved by people trying to

Beat the clock, oh, no I just don't know

I don't know, and I said, yes I said

(Background:)

People runnin' everywhere

Don't know where to go

Don't know where I am

Can't see past the next step

Don't have time to think past the last mile

Have no time to look around

Just run around, run around and think why

(I don't) Does anybody really know what time it is

(Care) Does anybody really care (about time)

If so I can't imagine why (Oh no, no)

We've all got time enough to die

Everybody's working (I don't) I don't care (About time)

About time (Oh no, no) I don't care

As a species we invented time. If we choose to change it around, move it, reverse it or whatever it's our doing as this has no effect on anyone/thing else.

Sure, we defined arbitrary lengths of time and made up words for those lengths of time, but there's nothing we can do to affect time itself. We can't stop it, slow it down, speed it up, reverse it, etc. It's a property of the universe and can't be changed.

Our universe would be pretty much useless without time.

That's not entirely true. Time can be influenced by traveling at high speeds and near heavy objects. It's not a constant that's everywhere the same. In fact our GPS satellites are suffering from this effect and the onboard computers are designed to compensate for that very effect.

but that is just a property of time itself - i.e. it will go slower for things moving faster, but we cant slow it down even more or not slow it down as much if something is travelling at a constant speed

Exactly. It's like 2+2 is 4, but 2+3 is 5. Change the variables, and you change the outcome. Even when your variables are arbitrary (for example, I say 2+3 is 7 because when I say 3 I really mean the value 5), you can't change the underlying rules behind those arbitrary values.

    • As I've been usually saying lately - we all can thank "AI" for this.
    • Friday Windows 11 preview builds are here. Insiders in the Experimental (formerly Dev) and Beta Channel can download builds 26300.8697 and 26220.8690. My Windows11 device on the Preview Channel just got 26220.8728. My guess is this build is a nightly update from 26220.8690.
    • Traffic has a surprisingly unexpected impact on your surroundings by Sayan Sen Image by Radik 2707 via Pexels A collaborative study by researchers from several Israeli institutions found that everyday pollution from traffic and industrial activity measurably changed the atmospheric electric field over the Tel Aviv metropolitan area, providing new evidence of how human activity can influence the lower atmosphere. The research was led by Dr. Roy Yaniv of the Hebrew University of Jerusalem and the Gertner Institute at Sheba Medical Center, Dr. Assaf Hochman of the Fredy & Nadine Herrmann Institute of Earth Sciences at the Hebrew University, and Prof. Yoav Yair of Reichman University. The study also involved Itay Froomer, a student from Hadera High School and the Israeli Museum of Medicine and Science (Technoda), who carried out the work as part of the Ministry of Education's 5-unit physics research track. The researchers focused on the atmospheric electric field under fair-weather conditions. Even in the absence of storms, a weak electric field naturally exists between Earth's surface and the atmosphere. One of the main ways scientists measure this field is through the Potential Gradient (PG), which is the inverse of the vertical component of the electric field. PG is a key part of the global electric circuit, a planet-wide system of electrical currents maintained by thunderstorms and electrified clouds around the world. Scientists have long known that the atmospheric electric field can be influenced by factors ranging from large-scale atmospheric processes to local weather conditions such as dust, fog and clouds. Human-made pollution is also known to play a role, but understanding exactly how urban emissions affect the electric field close to the ground has remained an area of ongoing research. To investigate this relationship, the team analyzed measurements from a newly installed electric field mill, an instrument used to continuously monitor the strength of the atmospheric electric field. The instrument was installed at the Center for Technological Education (Roter House) in Holon and became operational in August 2024. It was funded by Israel's Ministry of Education and the Holon municipality. The electric field mill forms part of a broader monitoring network that includes nearby meteorological stations and air-quality monitoring sites. This allowed researchers to compare electric field measurements with detailed weather data and pollution records to better understand what was driving changes in the Potential Gradient. The study focused on two major urban pollutants: fine particulate matter (PM2.5) and nitrogen oxides (NOx), both commonly produced by vehicle traffic and industrial activity. PM2.5 refers to microscopic airborne particles small enough to remain suspended in the atmosphere for extended periods, while NOx is a group of gases released during fuel combustion. Researchers examined daily, weekly and seasonal patterns in the atmospheric electric field and compared them with changes in pollutant concentrations. Their analysis revealed a clear relationship between NOx levels and changes in the Potential Gradient, particularly during morning and evening rush hours when traffic emissions were at their highest. “What we observe is a direct physical link between emission peaks and electrical variability,” explained Dr. Roy Yaniv. “NOx reduces atmospheric conductivity very quickly, so the electric field responds almost instantaneously during traffic rush hours.” Atmospheric conductivity describes how easily electrical charges move through the air. According to the researchers, nitrogen oxides rapidly alter this conductivity, causing a near-immediate response in the electric field. PM2.5, however, was associated with a delayed response. The researchers attributed this difference to the particles' longer atmospheric residence time, meaning they remain in the atmosphere for longer periods, as well as their different microphysical interactions with surrounding air and atmospheric components. The study also identified a pronounced "weekend effect." In Israel, traffic volumes and some industrial activity decline significantly on Fridays and Saturdays. During these periods, concentrations of both NOx and PM2.5 dropped, and corresponding changes were observed in the atmospheric electric field. “The weekend signal demonstrates just how sensitive the electric field is to changes in human activity,” the researchers noted. “When emissions decline, the electrical environment adjusts at once, providing a high-resolution indicator of urban atmospheric conditions.” The findings showed that pollution levels can influence not only the chemical composition of the atmosphere but also its electrical properties. Researchers said the results strengthened the case for using atmospheric electricity as an additional tool for environmental monitoring, particularly in densely populated urban areas where anthropogenic, or human-caused, influences are most pronounced. The study also pointed to potential public health applications. By combining air-quality measurements with observations of atmospheric electricity, researchers said they could gain a more complete picture of how urban atmospheric conditions change over time. “Integrating air-quality data with electric-field measurements gives us a clearer picture of how the lower atmosphere evolves moment by moment,” the researchers added. “It’s a framework that can support both scientific insight and practical environmental decision-making.” Beyond the scientific findings, the project highlighted a collaboration between universities, public institutions and secondary education. Researchers said the work demonstrated how students could take part in real-world environmental research while contributing to studies of air quality, atmospheric processes and their potential effects on society.

    • We aren't even at the all-star game and Microsoft is talking about an update that will most likely be released during the World Series if not after. A lot can happen in the world between now and the 2026 World Series, including the 2026 FIFA Cup. Tell me about it again after the FIFA Cup is concluded. That should allow plenty of time to prepare for it.
    • Great, tell me when I have a "Bad Pool Caller" elsewhere not in Windoze.
