Absolute Zero-
I recently heard that our entire solar system is flying through space at an extremely large speed (I do not remember the exact figure).
We believe that observations we make about our universe, and physics in general are "absolute." That our observations are true no matter where, or when we are in the universe (except for at or before the big bang.)
Would it not then make sense that our observations are actually "relative" to our velocity. Not only around the sun, but also our sun and solar system around our galaxy, and if we rotate around the sun, at a certain velocity, and the sun and solar system around the milky way at a larger speed, can we assume the milky way is moving around some super structure, moving at an even larger speed? What is our true velocity? What is our true "relativity?"
My real question
What happens at absolute zero? Not only in terms of temperature (my understanding being that absolute zero means no heat radiation, no energy ie; no movement (even at the atomic level), and absolute zero meaning NO velocity......
what happens if you put a science lab and telescope at a FIXED point in space?
Have we ever even put something at zero velocity?

No such thing as an absolute fixed point mate; every point in space that's fixed or in motion can only be described as such in relation to something else.

Yep, that's right. EVERYTHING'S relative, as Einstein's works suggest...

First off, Absolute Zero DOES NOT exist. Plain and simple. Or rather it exists, but it cannot be reached. It's like dividing a number by two. Keep doing it - you'll never get to zero. Temperature acts in the same way...nothing is ever devoid of entropy. You are right though - at Absolute zero, assuming a fixed object had reached that entropic level, there would be no energy, heat radiation or any kind of radiation. Forget atomic level. And velocitywould still exist. AbZero is a component of Thermodynamics. Velocity does not relate to thermodynamics. Motion is not the same as movement. Movement implies direction. Zero entropy does not mean frozen stiff and solid. There can be movement, but no motion emanating from the AbZero object itself.
