Okay, I know there are many threads about this and I checked some(adsbygoogle = window.adsbygoogle || []).push({});

like

Okay, let say we have a light cone http://img7.yfrog.com/img7/6463/lightcone3.jpg [Broken]

Where Vertical and horizontal axis representing time and space respectively

and L1, L2 & L3 represent path allowed for massive bodies, light and path not allowed respectively.

We travel at a speed that relates to path L1.

If we are stationary we'll just go through time, but no space.

Now, let's say we start to increase speed and time starts to dilates.

The more speed the more dilation.

At speed of light (which I know to reach is not possible atleast until we have much more advance technology) time ceases.

Why?

Because equations shows it.

But what if we look at it in a different way? Time ceasesbecausewe are traveling at therateat which time changes..

So, as we are also changing at the same rate, the time doesn't change according to our perspective.

Does this means that time travels at speed of light?

# Is speed of time c, atleast for someone travelling at speed of light?
