Espaço, Via LácteaAbstract
Aqui, será o “espaço” físico, o objecto. Para ir direita ao assunto, proponho: numa noite límpida e sem luar deite-se na relva, num local não poluído pela iluminação; olhe bem para o “céu” profundo, esmagador, nos milhares de objectos cintilantes. Contemple a sua beleza. E lembre-se que ocupa uma “nave” que se desloca, nesse espaço, a cerca de 29,8 km/s, em torno de uma estrela (como tantas outras…), o Sol. Mas tenha em conta que, em simultâneo, também ele (e todo o sistema solar) rodam a cerca de 220 km/s em torno do centro da Via Láctea, que pode vislumbrar sobre si, deslumbrante.
