00:00A crystal is a material whose atoms or molecules are arranged in a repetitive way, like on a chess board.
00:07Think of table salt.
00:10Sodium and chlorine form regular cubes.
00:13Quartz, silicon and oxygen align in a repetitive tetrahedral network.
00:19In snowflakes, water molecules create hexagonal symmetry.
00:23What matters is that these structures represent the minimum energy state of those materials.
00:30Atoms arrange themselves in these repeating patterns because that minimizes the total energy.
00:35That's why crystals are stable. That's why diamonds and quartz don't spontaneously break down.
00:41And now comes the question.
00:43If nature creates repeating patterns in the three spatial dimensions,
00:47could it also create a repetitive order in the fourth dimension?
00:51Well, time.
00:57Closed columnists could be transitioned by the other side before it falls like a
