4D (Empat Dimensi) adalah konsep ruang yang memiliki empat arah berbeda. Tiga dimensi pertama adalah panjang, lebar, dan tinggi. Dimensi keempat bisa berarti arah tambahan dalam matematika atau waktu dalam fisika. Dalam relativitas Einstein, alam semesta terdiri dari ruang dan waktu yang menyatu jadi satu sistem yang disebut ruang-waktu (4D). Kita tidak bisa melihat 4D langsung, tapi efeknya bisa diukur, seperti waktu yang melambat di dekat gravitasi kuat. #4d # #beranda
