Einstein's mass-energy equivalence is just one value for the velocity in kinetic energy equation. Am i right?

E = (mv^2)/2 is the kinetic energy equation. Here, sqrt(2) * c = 423970560 m/s, where c = 299792458 m/s is speed of the light in vacuum. E = (m*[sqrt(2) * c]^2)/2 = mc^2. ER=m*(423970560 m/s)^2,...

Anything that has mass also has gravity. Is it true?

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their...

In the Universe, all the objects (except running in vacuum) are orbiting other object(s)or moving in a circular path. Why?

I think these phenomena follow the scientific facts defined in the classical mechanics, but not theories or definitions in Einstein's mechanics.
