At 1:58, the moving clock is slower so 2L/C X gamma supposed to be the equation, shouldn’t it?
So, why we multiplied with gamma instead of division, and why C^2?
“Feel free to correct me” may someone suggest to me how? LOL. You are hilarious professor.

But if you will take GR in account, then none can cliam that they are in state of rest? I wonder does the ‘net’ time dilation incorporate both the effects for so called”Stationary objects”?! What ya think?

This concepts is in direct relation with the concept of ‘Eternalism’. Eternalism is a philosophical approach to the ontological nature of time which says,”Past, present and future all exist, exist simultaneous.” But it’s a debatab;le topic currently in physics. So we can’t agrre upon the concept until and unless we get a robust theoretical or experimental evidence.
What ya say?

What would be the integral(area under the curve) in space-time diagrams? Displacement?
And in conventional cartesian plane, where we chose y-axis as displacement and x-axis as time elapsed, in this one the derivative of displacement f(x) give us velocity and integral of the velocity f(x) will give us displacement. So, how do I incorporate the same mathematical principles in Space-time diagram?

But have we solved every mysteries related with speed? And at fundamental level Speed and velocity are same thing… so how do we know when to distinguish and when to not?
