مصير الأرض و الشمس و كل شيء | الدحيح
هل للكون بداية؟ هل له نهاية؟ حول هذة الأسئلة تصارع الفلاسفة ورجال الدين والخيميائيين والعلماء، وسادت أفكار أرسطو عن "قِدم العالم" لما يزيد عن الألفي عام، حتى أكتشفنا بالصدفة في بدايات القرن العشرين أن مجرتنا ليست الوحيدة في الكون وأن جميع المجرات آخذة في الابتعاد عنا بمعدلات سرعة تعتمد على قربها أو بعدها منا، لتولد بعد ذلك فكرة "توسع الكون" التي يمكن أن تجيب على سؤال هل للكون بداية وهل له نهاية، نكتشف في حلقة اليوم أن الكون مثلنا له ميلاد ومراهقة وفترة شباب وفي النهاية موت وتحلل؛ تموت فيه النجوم والكواكب والمجرات وحتى البروتونات والغازات الكونية والثقوب السوداء، ولا يتبقى في النهاية أي مادة تُذكر بعد أن استنفذ طاقته وتبددت تماماًالمصادر:
