A tesseract is a 4D cube, i.e. a cube that exists in 4 dimensions. Although fans of the Marvel universe and superheroes may associate tesseract with the glowing blue box that houses the Space stone, a tesseract is a real geometrical concept that exists in four dimensions. Here is a simple way to conceptualize dimensions: a square is a 2D shape, so each of its corners has 2 lines coming off it at 90 degrees to each other. A cube is three-dimensional, so each of its corners has 3 lines coming off it. Similarly, a tesseract is a 4D shape, so every corner has 4 lines coming off it. Mathematically speaking, a tesseract is a perfectly accurate and plausible shape, as are all shapes in higher dimensions, such as 5D and 6D. Just as a cube can be unfolded into 6 squares in 2D space, a tesseract can be unfolded into 8 cubes in 3D space. #science #animation #tesseract References: https://sites.pitt.edu/~jdnorton/teaching/HPS_0410/chapters/four_dimensions/index.html http://www.math.harvard.edu:80/archive/21b_fall_03/4dcube/ http://www.geom.uiuc.edu/docs/outreach/4-cube/ Original Article Link: https://www.scienceabc.com/pure-sciences/what-exactly-is-a-tesseract-real-life-geometry-4-dimensional.html If you wish to buy/license this video, please write to us at admin@scienceabc.com.
