فضاء وفلك

الزمكان | Spacetime

18 يوليو 2019

هو مفهوم يساعد في فهم كيف تعمل الجاذبية في الطبيعة بحسب نظرية النسبية العامة لأينشتاين. الزمكان هو نسيج يتحد فيه الزمن مع المكان (الفضاء ثلاثي الأبعاد) ليصنعوا بنية رباعية الأبعاد التي يتكون منها الكون، يتشوه أو ينحني هذا النسيج نتيجة الكتل التي تتحرك فيه مثل النجوم وغيرها. هذا التشوه هو ما نعرفه بالجاذبية. ومن هذا المفهوم تؤثر الكتل (الجاذبية) في المكان (الفضاء) والزمان (مرور الوقت).
