In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values (coordinates) are required to determine the position of a point.
26 gru 2011 · Learn how superstring theory and Big Bang cosmology can explain the origin of 3 dimensions. Find out how a supercomputer helped researchers calculate the interactions of strings and the expansion of space.
11 gru 2014 · The third dimension involves depth (the z-axis), and gives all objects a sense of area and a cross-section. The perfect example of this is a cube, which exists in three dimensions and has...
23 paź 2017 · A new theory suggests that flux tubes, which are strands of energy that link quarks, can form knots and links that stabilize the universe in three dimensions. This theory also explains inflation, the exponential expansion of space after the Big Bang, and agrees with string theory and gauge theories.
1 sie 2023 · Learn about the three spatial dimensions (length, width, and depth) and the fourth dimension of time. Discover how string theory and other physics theories propose more dimensions that are too small or curled up to observe.
25 wrz 2013 · A physicist explores the perplexing question of why space has three dimensions, rather than two or four. He suggests an answer hidden in the workings of physics we already know.
3 kwi 2014 · Learn how physicists use mathematics and observations to explore the number and nature of dimensions in the universe. Discover the evidence for three spatial dimensions, four spacetime dimensions, and the possibility of extra dimensions beyond our perception.
