    Displacement Time
AI Thread Summary
The discussion revolves around how to label displacement through time, specifically questioning the units used to measure motion through time. Participants suggest using seconds as a standard unit, while also exploring the relationship between movement through space and time, particularly in relation to the speed of light. The conversation highlights that the measurement can be expressed as a product of the speed of light and time, suggesting that meters can also be a relevant unit. The exchange emphasizes the importance of understanding the interplay between time and space in physics. Overall, the dialogue seeks clarity on the conceptual framework for measuring displacement through time.

I was wonder what units you would use to measure your motion through time?

How about seconds?

I'm talking about movement through space combined with movement through time is equal to the speed of light. we measure time in seconds but what does a second actually stand for?

It's actually ##c\cdot t## what we measure, so meter will do.

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
