  1. As Einsteins relativity suggests that everything slows down along with the speed of light. So, if we were to live in space would our thinking capability (essentially speed) increase or decrease (due to the increase in light's speed)?

  2. Also, can we change (increase) our thinking speed by staying as still as possible?

    (1) The speed of light in vacuum is invariant, (2) we are at rest with respect to ourselves, (3) the relative motion of another frame of reference doesn't affect our thinking speed (4) what is present for one observer is past for others and future for others still. – Alfred Centauri Mar 10 '14 at 18:45
  • A thought is just an electrical impulse (in simplest terms). Thus, I'd assume the signal's speed would determine the speed of a "thought". A neurologist would probably be able to shed more light on this. – turnip Mar 10 '14 at 20:28

Yes, if you lived in space far from the Solar System you would think slightly faster than you do on Earth.

However the connection to velocity is a red herring. As Alfred says in his comment, you're at rest in your own rest frame so you're already thinking as fast as you can. Re your Q2: the fastest speeds regularly experienced by humans (airplane flights?) make so little difference that they can be ignored, so I wouldn't bother making the effort to sit still.

However there is a small time dilation due to (a) being in the Solar System's gravity well and (b) being on the Earth that is whizzing round the Sun. There is a calculation of the time dilation in the question Time Dilation Effects from simply being on a spinning planet orbiting a star in a rotating galaxy in an expanding universe.. The result is:

$$ \frac{t}{t_0} = 0.999999984 $$

So someone floating in space far from the Sun and at rest with respect to it would be thinking about 0.000002% faster than you. Hardly worth the effort really.
