Hello forums,

I'm kind of new nice to meet you guys and girls,

Could someone please explain this to me?

D=S * T


Therefore Distance = Speed of light * Time


And then Distance = Speed of light + 7 * Time


What is Distance and what is time?

If you increase the speed,then the time required decreases to cover the same distance.

Is there anyway to decrease the speed of time so that the speed of light increases, perhaps in all honesty change the distance too because I heard that there is a fabric to space.

Welcome to PF!

I'm sorry, but this all really doesn't make any sense. The equation says if you go a certain speed for a certain time you go a certain distance. That's it. Not sure why you'd throw a "7" in there...

And the speed of light and rate of passage of time are always the same for you.

There is no such way. And spacetime is not a fabric. That's an extremely simplified analogy that doesn't represent the full picture, namely that spacetime is represented mathematically by a 4D manifold.

Distance is that which a ruler measures, and time is that which a clock measures. :wink:
Seriously. That is a basic definition of distance and time. Even Einstein's papers on Relativity use a form of these basic definitions and our ways of teaching relativity involve problems in which we literally insert clocks into different frames of reference. There is no confusion or ambiguity in nearly all of physics about what these things are. If you hear otherwise, then you are dealing with highly theoretical physics, something outside of physics (such as philosophy), or you're dealing with someone who doesn't know what they are talking about.
