you can't just pwn maths
You can!
Ask the theory of relativety, my friend.
I'll give you an example!
We all know that, 300 000 kilometer/second is the speed of light.
And we all know that 300 000 splitted in 2 always equals 150 000.
But the last part is wrong!
It aint always 150 000.
Why?
Well, Einstein gave this example,
You are standing infront of the sun and the light passes you with the speed of 300 000 km/s.
And here's the odd part.
You fly away in half the speed of light (150 000 km/s)
logicaly, the light should now pass you in 150 km/s, but,, it doesn't?
It still passes you with the standard, 300 000 km/s.
1+1 isn't always 2, etc..
Light travelling in vacuume always passes you with the speed of 300 000 km/s.
