I'm interested in calculating the total velocity of an object on earth from the farthest frame of reference (the observable universe). I apologize that I am not a physics or science major so please bare with me.(adsbygoogle = window.adsbygoogle || []).push({});

I've posted on another google forum and was told a few different ideas.

Initially I used normal vector addition to add the velocities of the rotation of the earth, the orbit around the sun, the movement of the sun in the galaxy, and then the movement of the galaxy in the universe. When I do that with the numbers I have I get:

3 000 900 km/hr.

I've tried adding the velocities using the formula linked to for special relativity

u + v

w = ---------

1 + uv/c2

and I got this:

3000895.06594378 km/hr

which is -4.93405622430146 km/hr difference than the normal vector addition I performed before to get: 3 000 900 km/hr.

Does that sound right?

Basically If a ball was rolling on a table at a certain velocity on earth, I would like to know the total velocity it is moving taking into account ALL of the cosmological motion it exists within (also taking into account SR). Does this question have a quantifiable value?

Thanks for your time.
