Cosmological Evolution (Part 5)

OK in the last post I said that…

Energy In is the matter and energy used to create our Parent Black Hole. And Energy Out is the net matter and energy that makes up our universe.

…and that our universe must balance the energy equation

Energy In = Energy Out

…such that it consumes an amount of energy equal to the amount of energy being fed into it.

So the question is…

Why does the emergent universe, our universe, evolve the way it does – with, matter, stars and us?

Well, let’s consider the range of possible universes by varying or “tuning” the universal physics constants such as the speed of light, vacuum permittivity, Planck’s constant, or the gravitational constant.

It turns out that most possible universes are quiet uneventful, with settings that don’t involve matter that clumps and stars that shine. Thus, they don’t end up balancing the energy equation and therefore, won’t end up emerging. In fact we know of only one setting for the universal physics constants that results in a universe that does involve energy – and it’s the one that we inhabit!

So it’s not an accident that the speed of light is 299,792,458 meters per second, or that Planck’s constant is 6.626176 x 10 joule-seconds. This combination of settings results in an “energy eventful” universe that can balance the energy equation.

So why then did life emerge? I mean, it’s possible to have an “energy eventful” universe that doesn’t involve abiogenesis – where life doesn’t emerge. Well that’s the topic of my next post… stay tuned.
