"Pulsatai | Science & Engineering." on Instagram: "Most of us can visualize 3D space easily... width, height, depth. But physics and mathematics don’t stop there. A 5-dimensional tesseract (also called a 5-cube or penteract) is a geometric object that extends a cube into five spatial dimensions. We can’t perceive 5D directly, so scientists use projections and “shadows” to visualize it. The way a 3D cube casts a 2D shadow, and a 4D tesseract casts a 3D shadow, a 5D tesseract projects into our wor
