Planck time
History
Time has always had a somewhat neglected character in modern physics, although Einstein added such crucial things as time diletation, differently running clocks, etc ... But it would only ever be seen as part of a four-dimensional space-time and itself only as one-dimensional. Max Planck's quantum theory of time is similar, again everything is built up from a one-dimensional period of time. The elementary time is: t (p) = 5.39124 · 10 ^ −44 s.
Theoretical conclusions
From the equivalence of space and time the assumption arises that time must always be just as dimensional as space. Sounds reluctant because time keeps ticking away. But just as space is three-dimensional for us humans, time must also be three-dimensional, because space and time are so closely linked in this way. In a four-dimensional space we would consequently also have a four-dimensional time and a total of an eight-dimensional space-time continuum. For us humans there is only a 6-dimensional space-time continuum. In the same way as the earth rotates around the sun, spatially speaking, time also rotates; a year goes by with spring, summer, autumn and winter. And just as the earth revolves around itself, a day goes by from morning to evening and night. That's what I mean by this equivalence.
