I am looking for exact specifications for tandem vandegraff accelerator. this would include measurements, materials, everything. I need this information to completely understand how they work, but I am unable to find it anywhere. a 3D model of it with noted materials and parts would be the best. anyone have anything like this?

Does this equation encapsulate the concept that I need to understand?

right, and this is possible because of some space time warping right? Time is hardly moving for the space ship, because it is moving almost the speed of light. so, what is actually light moving only a little faster than the space ship appears to be light moving at light speed. wait... if time is moving slower for the ship then why would that make it look like the speed of light stay constant? Merged post follows: Consecutive posts mergedI am talking about relativistic kinematics right? This can be understand perfectly mathematically right? where time is a fourth dimension.

Here is what I believe to be truth: 1)The Speed of light is constant in any reference frame 2)Nothing can go faster than the speed of light (Including light) Let us say that there is a space ship with a headlight which is flying away from the earth at light speed. It then turns on its headlights and the light goes zooming away from the space ship at.. once again.. lightspeed. In reference to the earth, wouldn't the light be moving away at twice the speed of light?
