Exactly. I understand that perfectly, but it seems to contradict some of the notions about relativity and time dilation. Perhaps it is because I do not understand it fully. So what you are saying is that a moment in time is the same for everyone no matter where you are, correct? Then how is...

With all due respect, how is "instantaneously" not clear? I know it is impossible, but we are talking hypothetically to make it easier to explain what I am asking. I could rephrase the same question to ask what does an observer 1 light year away from the Earth see? They see what Earth looked...

Ok... Let me rephrase some of that. Lets say someone is able to teleport instantaneously from Earth to 1 light year from earth. If they look at earth, they will only see the light from the Earth from one year ago, would you consider that person to have traveled a year into the past? Lets...

Thank you everyone for the replies, I really appreciate it. I have been scouring the web trying to learn more about time and what it really is, and I think I am starting to get some of the theories a bit more. I do have some follow-up comments/questions if you don't mind. First let me...

So can the following statements all be said to be true? -Clocks measure time -The definition of time is a measurement of a physical process -All physical processes are affected by speed and gravity

Is my way of looking at it somehow flawed though? Is it possible that the time dilation we see is a result of the effect on the instruments we use to measure time, and not time itself? This has always been my biggest problem with understanding time dilation.

Hmmm... I accept GR and all that, I am not trying to dispute it, but can it not be said that time is a constant, and its the tools we use to measure time that change with speed and gravity, and therefore the time dilation we see with a clock is not necessarily a change in time itself, and only...

So with the idea that clocks are just a physical process, is correct to say there a difference between 'time' and a 'physical process'? I guess what I don't understand is if clocks are affected by speed and gravity, how can they be a reliable tool to measure time?

Hi Everyone, first I want to say I have no formal education or background on these topics, but find them very interesting and research and learn as much as I can on my own. With that in mind, I am hoping some of you will have the patience to explain what I don't seem to understand. What I am...
