I want to know how much spacecraft speed in the space for traveling in future. Because i believe one day human must be traveling out space there to find the another place for survive but with how much speed can be..?

Current thinking is that an infinite amount of energy is required to accelerate even a very small amount of matter to the speed of light, but we used to believe that airplanes could not withstand speeds higher than the speed of sound. Who really knows what the future will bring?

Wrong question. Two "better" ones:
1. Can humans live off the earth "sustainably" (this means can we establish a self-sustaining ecology with only energy as an input - like the Earth is - This is like ths sci-fi idea of a space colony) Answer: we don't know how.
2. Can humans live in space for long periods of time and keep healthy? Answer: We don't know how but probably not.
It will be cheaper (and faster) to send our DNA and social knowledge via robot and reconstruct people at a hospitable planet than to travel there. One way trips are not so fun.

I do agree that humans need to master how to live on this Earth a lot better than they do now, before going off into space and crapping up some other planetary object.
That aside, until someone shows me how the speed of light can be surpassed, within my puny capability to reason, I don't think we get any faster without some new dimension of physical laws to content with.

The same (3*10 to power8m/sec)This speed is for vaccum

If your speed approaches the speed of light ,How do u see what u are ruining into.??
