The answer is; TRUE
When the saturated solution is allowed to cool slowly, the molecules in the solution have the time to displace impurities that try to attach to the growing lattice because they fit perfectly, geometrically then the impurities. This way the lattice grows larger.
If the solution is cooled fast, the impurities have little time to be displaced from the lattice hence the geometry of the crystal lattice is disturbed and the crystals are smaller and less pure.
That depends on what you mean by ripples at the beginning of time. If you are referring to inflation of the universe caused by the Big Bang, and the subsequent "ripples", then those ripples are the leftover, background radiation from the event. If you are referring to ripples in space-time, then it still could have multiple meanings.
