that the probability of a kaon transforming into its antikaon
is different from the probability
of an antikaon transforming into a kaon,
so weak interactions violate P, C, and CP-symmetries.
Mirror images
If the future were a mirror of the past,
hey, we’re in trouble, mister.
The farther we get from the past,
the rosier it seems.
The future reflects what we see around us,
but we can’t step into it.
T violation
If you think about time in spacial terms,
you could think it travels in only one direction,
but time is different from space. It’s
not like width, breadth, or height except on a chart.
There’s no way to travel to the future
except the slow way, one millisecond at a time.
When shit happens, it’s not beside,
above, or below; it’s all over, then it’s over.
At this time, it seems, still,
no one knows why these things are not symmetrical.
It’s just that, conveniently, if they were symmetrical,
then there would be as much antimatter as matter in this universe,
which could mean that we would be creatures of pure energy.
