So, how come speed of light is fixed and not the unit of time??!!!

In addition, Einstein says light cannot escape a blackhole, so what it means light velocity is 0 and not the C, or time is always is 0 or both are 0.

So, how do you define time. Seconds, minutes, hours, days, years are all units of time. But to give a good definition, you cannot use terms that derive their meaning from the concept of "time." So how does one define time? During that philosophical discussion, we pondered as we imbibed. Ponder as well my friends. We came up with a definition. Can you? This pertains to Einstein's theory directly, or space and time would not have a correlation.

I believe you are talking about Special Relativity.

I would define time as the duration between events. But then how do you define duration without referring to time?

Time, is simply d/v

And that is exactly the problem with DEFINING time.

I need to imbibe some liquid refreshment.
This whole thread is taking up too much of my time.

Proper time or coordinate time? Observers?

I was once asked if a car was traveling at the speed of light and turned on it's headlights would any light escape? I answered with a question. Is the car in forward or reverse? The guy moved on to the next question?

As for black holes I don't know if anything can escape. I do know that Borger, Texas is the closest I've ever been to a black hole. I spent a week there one night.
