It could give your enemy more time to prepare. You could find your family line went extinct. I don't like myself. I don't trust the fuzzy math involved in black holes. I wouldn't pass the physical.
Animals are also attuned to seasons, feeding time, etc. Yes, humans divide up time with sundials, watches and calendars, but time exists whether we notice it or not. The Earth will still spin and will still orbit the Sun. In time, the Andromeda galaxy with merge with the Milky Way regardless if anyone or anything is attuned to time passing or not.
Thus you have proven that "Time" is a completely human centric concept and creation. It is not only human centric it is individualized. A "Day" on Jupiter will be about ten hours long for a Europian watching from his Ice tower and a winter month in Siberia will seem much longer without a watch to track the manmade passage. Would time exist if we had no way to measure it?
Of course, we would still age and seasons would come and go. The earth and many things on and about it existed before we had a way to measure them.
Yes because that's what we know in our locality...it's the way we plan and organize and communicate. In this regard time is real. And I suspect if we were communicating with Alpha Centauri we would need to make a time reference conversion. I wonder if there are clocks aboard the Voyager's that can be compared to time on Earth? If something is moving then there must be time...
One can communicate with GPS standing here on earth in the same gravity well as others and experience the difference in time nearly instantaneously with that satellite and yourself. So the minute there is different than your minute although you are utilizing information immediately or as close to that as is possible. If you are using the same information are you intertwined and/or coupled in any quantum fashion? Time is very likely to be quantum and obviously moving forward when left to its own nature.
We associate the passing of time with increasing entropy. But that doesn't make it fundamentally real.
Our perception of reality is based in our brain. Can you describe quantum packets of time assuming that is actually time in a way that does not involve the human perspective? Time must occur in some fashion even if we can't describe it well. We can 'see' the past and peer into the future even if only with our imagination. While I describe this in human perspectives nevertheless it exists just as I do.
Time!? An invention of PeopleKind No People. No Time. I have a watch on my left wrist that proves there is time.
If time wasn't relative, it would be easier to dismiss. But the fact that our measurements of time can be altered by the state of the system, means that something real has to be changing. I was reading earlier that the notion of quantized time is on the outs now. But you never know. There are many schools of thought in physics when it comes to the deep questions. When you get an answer on something like this, it may only represent a small fraction of the views that exist. It took me awhile to realize that physicists rarely provide an overview of the many schools of thought that may exist on a given subject. They are not democratic! They talk about their own school of thought as if it were the only one. Some of the most brilliant minds in history considered some of the other most brilliant minds in history to be crackpots. Fermi was asked what characteristics physics Nobelists had in common. He answered, "I cannot think of a single one, not even intelligence." Enrico Fermi, Italian physicist, 1901-1954 (Phys Today, Oct 1994, pg70)
...Uh...humans not only made clocks, we are the only ones who can read, use, or understand them. Clocks most certainly "Depend" on human perception.
To me there is this concept called space time, which physics uses and then there is another kind of time which I can only call psychological time. There may or may not be a real relationship, in reality. As some ancient philosopher once said, "I know what time is, until you ask me what time is." I feel that psychological time is a creation of consciousness itself. It arises with our kind of self awareness and the ability to separate ourselves from the rest of the universe. I do not think other animals separate themselves, they are just a part of the Whole and unaware of any separation.
I'm not a physicist, but I don't believe Einstein was arguing there was no time. He argued that time was real, but relative.
It's a measure of convenience. When would you schedule an appointment? When would a store open? When would I be early or late for work?
I think he means it took perception to make them? And perception to read them. Clocks are a creation of human consciousness. And they do that exist without that. I think that may have been his point. We have a sense of time. This was a creation to measure it more accurately.
Clocks exist independent of human perception. We merely assign units of measure. A pendulum swings whether or not anyone is watching. Time is passing.
LOL! Talk about a closed mind! You do know I'm a physicist, right? I've had more than a passing interest in this subject. How about you? Studied a lot of physics did you?
As understand it, scientists now feel the term causality is more precise than the more common term “time”. The reason for the Change is that We think of time as being absolute in a way that it is not. For example, consider a lightning strike. We will see it, then hear it later. So in some sense the event seems to happen at different times. This problem is overcome through the concept of causality. There is some event that cause a flash of light and a sound. These are independent events that are causually related to the initial lightning strike, but the light and sound are independent causal events with their own physics that are independent of the initial causal event (the lightning strike). So, for example, we see a star shining in in what is apparently present time... and yet the actual causal event happened long ago. So time refers to our relativistic perception of causal events. Which in most circumstances is adequate for living our lives, but is subjective
