what basically happens is that gravity bents space & time fabric. the light travels parallel to space & time fabric so at a point the fabric is stretched and light have to travel twice as long so that's why they say light cannot escape a black hole. As Eisenstein said that c is the optimum speed...

solved... arcs form one complete circle... ty

i did check it manually and i was wrong.the algorithm is just to identify the points that stick out!

i see it forms a single circle! if the perimeter is (25.20983226924521) + 2*3.1415926535897932384626433832795 is 31.493017576424796476925286766559 not even close to 34.408

i do not understand what's wrong so if i draw tangents on the outside it will join and form a pentagon and the internal angles are 540. so what am i doing wrong? please help me!

in the picture there are 5 mines that stick out. so the internal angles is 540 degrees so the length of the arc. rather than 360 degrees this is 540 degrees that's how i got ~ 9.424

yes i did look above ^^

and also let's say i have multiple points refer the pic and the points are x y 1 4 3 2 7 9 5 4 9 5 6 7 9 1 11 8 the radius is 1 unit i did a convex hull algorithm and found the perimeter and added the arc length. since it is a 5 sided polygon the interior angles are 540 degrees the total...

so if both circles have the same radius then the distance between the radaii is the length of the tangent right?

related equations and formulas http://en.wikipedia.org/wiki/Belt_problem#Pulley_problem image http://upload.wikimedia.org/wikipedia/en/0/07/Straight_Belt_pully_diagram.GIF so, i need to know the equation for finding the length of the tangent. please read...
