It's not about being sure. It can't be so in our fundamentally quantum<br>
universe. It's about probabilities not certainty. It's about constantly<br>
updating your model to fit any new data. Your brain evolved to learn, not<br>
to know.<br>
<br>
No physical theory is ever guaranteed to correspond to the real world.<br>
Such are only contigently true until a phenomenon occurs that violates<br>
their premises or until a theory of greater scope or accuracy comes along.<br>

There does not seem to be any upper limit on the size and mass of black<br>
holes. The universe could be an infinite swarm of black holes inside<br>
bigger black holes all of them constantly colliding and merging. Each<br>
black hole with it's own internal vacuum state / zero point energy, each<br>
successively larger one at a lower energy level but never actually zero.<br>
<br>
Event horizons might simply be boundaries between different vacuum states.<br>

It is infinitely recursive dualities all the way down.<br>

Due to your brain's limited processing speed, your visual "now" is 80,000<br>
nanoseconds in the past plus one nanosecond in the past per foot the event<br>
is away from you. It's even further in the past if you are talking about<br>
your auditory or tactile now.<br>
<br>
Furthermore you cannot distinguish the temporal order or causal<br>
relationship between any two events less than 80,000 nanoseconds apart.<br>
<br>
If there can be no sharply defined and meaningful now, then how could<br>
there be a sharp meaningful beginning? Therefore there is no beginning,<br>
there is no now, and there is no end.<br>
<br>
Just continuous relative time with one moment blending imperceptibly into<br>
the next. Running at different rates for different observers and in<br>
different orthogonal directions for observers in different causal cells.<br>
