ok so you have a few questions here firstly you could in theory make a sheild to cover the whole planet but the amount of required energy to create even the most basic of sheilds of this size would reqire an astronmicle abount of energy. and secondly NO it is not possible to make a completly impervious shield. as the article said that all shield types have a weakness for example a particle shield's weakness would be a series of extremly high velocity attacks that fragment and keep going when they strike the particles of the shield. but you can build sheild layers to better protect yourself or make a construct capable of doing so itself.
