english: Einstein also realized -- and this is the real meat of the matter -- that if you put energy or mass in the universe, it would curve space, and a freely falling object would pass by, let's say, the Sun and it would be deflected along the natural curves in the space.
non_english: Einstein si tiež uvedomil, a to je to jadrom veci, že ak do vesmíru umiestnite energiu alebo hmotu, tá zakriví vesmír a ak by voľne padajúci predmet prechádzal, povedzme, okolo Slnka, odklonil by sa pozdĺž prirodzených zakrivení v priestore.
