# I What is a time warp?

As matter causes the space to warp, does time also bends or warp due to mass?

Well there is an effect called time dilation.
This causes time to appear to pass more slowly for an object which is close to something very massive like a back hole.
The slowing down is at it appears to a distant observer, the object itself if it was a sentient being would not notice any difference to the passing of time.

Space and time are not separate entities they blur together forming space-time under GR.

Rootone - I am aware of the concept of time dilation but this time warp, is it same as the time dilation or is it something entirely different concept. I tried searching for the term but could not get any success.

I am not sure you mean by the term 'time warp' other than in the context of dilation.
Can you provide a reference to what you are talking about?

The Lorentz factor is given by $$\gamma = 1/(1-\frac{v^2}{c^2})^\frac{1}{2}$$ Length contraction is given by $$L=\frac{L_0}{\gamma}$$ and time dilation is given by $$T=T_0\gamma$$ So, L & T are inversely proportionate. When distance is expressed in terms of the speed of light: D=cT; D = distance, T = time and c=1 [in natural units]. This reduces to D=T, so the two are the same thing from this perspective.

Surely "time warp" is a Science Fiction term. I can't think there will be any rigorous definition.
