The real reason of "time dilation"

No, it's not "because Nature works that
way". It's not that your idiot guru has
caught God's balls, not at all.
As the idiot has persuaded you that time
is dilating - you've created new methods
of counting it, giving the results as
he has said.
A genaral rule of "laws of physics":
they're not about "how nature works",
they're about "how your minds work".
