What happen if there was no stars?
Nothing. They are so far away that they have no effect on us apart from being pretty lights. Of course the sun is a star, and if that went away then the temperature here on Earth would quickly get down to -270C and we would all die. x[

Why is it important to put rubber insulation on a PPR pipe?
PP-R piping is a polypropylene co-polymer pipe used for water service in Europe. It is manufactured from petroleum products, a non-renewable resource. It melts, for "welding" together at 270C (518F) and burns at 330C (626F). The combustion of this plastic produces less toxic fumes than other plastics. It can handle pressures up to 320 PSI and hot water up to about 140F safely without leakage. It is not recommended for outdoor use where it is subject to UV breakdown, Insulation is unnecessary, except to protect it from UV radiation. Otherwise, mounting hanging and use of this pipe should follow normal plumbing codes.
