AI Thread Summary
The discussion explores the relationship between space and time, questioning whether there is a hierarchy between the two dimensions. The author suggests that space and time are not equal, as changes in spatial dimensions depend on time, while time does not depend on itself. They propose that time may be a function of gravity, which is tied to mass, leading to a fundamental uncertainty in understanding time's nature. The conversation highlights the complexity of defining time in relation to spatial dimensions. Overall, the author seeks clarity on the hierarchy of space and time within the framework of physics.

Hi, not anything close to a physicist, but was interested in a question:

There are four dimentions in the visible universe - three space and one time dimention.
Is there any hierachy between the space and time dimentions?

To me space and time do not seem to be on an equal footing becase the physical dimentions are a function of time (for example a change in distance is proportional to time) but time is obviously not a function of itself.

If that makes any sense to anyone, then what is time a function of? I don't see anything other than gravity myself. Gravity is a function of mass, and that being a somewhat unexplained phenomenon fundamentally you get stuck there... ... That was a bit of a rant, but just wondering about the hierachy thing - I just can't see them as equals because time can describe aspects of space, but not the other way round.

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
