As some experiences from scientists the light has maximum speed about 3*10^8m/s even though if two lights move against to each other

no not collision but not different you can suppose that they strike together .

This is literally the most confusing thread I've ever read. The answer the initial question is that in relativity, velocities don't add like that. The relativistic velocity addition law is \[v_{rel} = \frac{v_1+v_2}{1+\frac{v_1 \cdot v_2}{c^2}} \] at small velocities, this is approximately \[v_{rel} \approx v_1 + v_2\] which is what we use in everyday life.

mahmit2012 Group TitleBest ResponseYou've already chosen the best response.2
ok and if v1=v2=c then vr=(c+c)/2=c so I just want to show that why.

That conclusion seems to have been drawn COMPLETELY out of thin air. Your rationale appears to have something to do with spatial rotations and hyperbolic functions which by some wayward tangent could I suppose be related to Lorentz boosts and rotations and the addition of rapidity rather than classical velocity but it is only through the most indirect channels that I could draw that conclusion, and if I knew nothing of relativity this would be meaningless!

Jemurray3 Group TitleBest ResponseYou've already chosen the best response.1
I already know relativity. I'm just making the point that unless somebody was already well versed in relativity beyond the undergraduate level this would be completely meaningless, and even if they were this would only indirectly and momentarily flirt with coherence.

if you would like to know how the Laurence formula are made from hyperbolic functions go and watch a lecture in Stanford modern physic in youtube in this site: http://www.youtube.com/watch?v=BAurgxtOdxY

Like @Jemurray3, I am completely unsure where this thread is going and almost uncertain where it began. As such, Je has acquired the best answer from me.

It began just for a individual person as an introduction not an academic lecture so I offered to jemurray3 a site for that.

If somebody asked you to explain basic mechanics to them, would you start ranting about Lagrangians and chaotic dynamics in phase space, or would you talk about bouncing basketballs and blocks on inclines?

I found out this way for a person who know rotation is better.so if you have any suggestion I would like to hear from you.
