Things that Yoram knows: why are there 24 hours in a day and who decided what time it is?

The day is divided into two dozen hours because the hour was born even before the decimal system defeated the competing base 12. The fixed hour is a relatively new invention

The arrow of time works differently in the quantum world

Does time inside black holes move backwards?

A rare hour. The earth slows down and so occasionally it is necessary to add a second to the year to coordinate the real time with the coordinated universe time set by an atomic clock. Photo: shutterstock

Einstein - the man who started to take us out of the matrix (part 1)

That's it, it's official, the theory of relativity passed another test and the neutrino particles that seemed to contradict the theory of relativity and move faster than the speed of light, don't really do that
