The Meaning of Life, Part 1: Cosmic Perspective

This trilogy is not like the Monty Python version, there will actually be more parts.

Lots of folks say we need to abandon American exceptionalism.  Some, like my Dear Uncle Napoleon, prattle on about British exceptionalism.  Today, rather than taking on either of those two comparitively minor annoyances, I hope to kick the shit out of both Homo sapiens sapiens and Planet Earth exceptionalisms.

A single member of the H. sapiens sapiens race is, on average, 664 billionths (10-9) km3 in volume, with an average lifespan of 67.2 years.  There are currently 7.3 billion (109) individuals of that race on Earth, or Terra.

Earth, or Terra, is 1.12 trillion (1012) km3 by 4.54 billion years.  It rotates on its axis at a speed of 1674.4 km/h while revolving around Sol at 108 thousand (103) km/h.

Sol, our system’s star, is 1.4 quintillion (1018) km3 by 4.56 billion years.  The Solar Planetary System is 1.7 duodecillion (1039) km3 by the same 4.56 billion years.

The Milky Way Galaxy is 8 sedecillion (1051) km3 by 13.2 billion years.  Of its 200 billion stars, 40 billion support Class-M planets, with 8-10 billion of these hosting life-forms analogous to Humans, making some 61.6 quintillion (1018) sapient beings in our galaxy.

There are 2 trillion (1012) galaxies in the Universe with 80 sextillion (1021) Class-M planets hosting 123 nonillion (1030) sapient beings in the Universe at any one time.

The Universe, the ‘Verse for short, is 213 duovigintillion (1069) km3 by 13.8 billion (109) years.  It is expanding outward at a rate increased by the like-polarity of the electromagnetic fields of different galaxy groups.  And it is just one of innumerable such cosmic bodies making up the Omniverse (aka Multiverse), and is currently the only one we can measure.

The Universe is formed of a single matrix called spacetime. 

Everything in the ‘Verse not of the matrix of spacetime is composed of energy.  Energy can be neither created nor destroyed but only change forms.  All matter that exists is but alternate forms of energy. 

Spacetime and energy are thus the fundamental building blocks of the ‘Verse and everything in it, the emanations from which all that is evolves.

There are four basic dimensions—height, length, width, time—which define the point in the spacetime matrix at which we are at any given moment.  Energy flows to and from that single point in spacetime—forward and backward, up and down, left and right, past and future—along each of these dimensions.

The force of gravity provides the cohesion for the ‘Verse in a relationship with the dimension of time that is correlative if not causal.  Without gravity, there would be no time; without time, there would be no gravity.

Life is a function of energy, of thermodynamics.  Given appropriate conditions, life is inevitable, because energy in the form of matter will spontaneously self-organize through abiogenesis.

Once manifest, life evolves into more complex forms which themselves evolve further, with those most adaptable being the best able to survive, reproduce, and flourish.

Life has existed on Terra for 4.1 billion years, and in the Universe since 10-17 million years after the Big Bang.

The essence of life is change and evolution, growth and decay.  For individual organisms, birth and death define the boundaries of life.  Without death, life has no meaning.

Whether or not there is another form of existence once the organic shell has been shed in death and life on this plane ends does not matter; Humans debating those questions are like fetuses discussing questions on life after birth.

In 5 million years, the H. sapiens sapiens race, and along with it the H. sapiens species and the Homo genus, will be extinct due to degradation of the Y-chromosome, if we have not already destroyed ourselves and/or our biosphere or suffered a mass extinction we don’t cause.

In 800 million years, multi-cellular lifeforms will have vanished from Terra.

In 1.3 billion years, eukaryotes will be extinct and life on Terra reduced to prokaryotes due to CO2 starvation caused by chemical disruption from Sol’s increasing luminescence.

In 2.4 billion years, the Milky Way Galaxy and the Andromeda Galaxy will collide and merge into one Milkomeda Galaxy, altering the structure of everything in them, though most stars and planetary systems will remain intact.

In 5.4 billion years, Sol will enter its red giant phase, incinerating Mercury, Venus, and possibly Terra, destroying any remaining life on Terra if not.  The habitable zone will move out to Mars, and Saturn’s moon Titan may become habitable.

In 8 billion years, Sol will collapse into a white dwarf, expelling half its mass into the interstellar medium, making elements available for nucleosynthesis and forming an emission nebula.  Any remaining planetary bodies will be stolen by passing stars, leaving the Solar Nebula.

In 14.4 billion years, Sol will be a totally dead black dwarf star.

The Universe will eventually end in the next Big Bounce (a Big Crunch facilitating another Big Bang) in around 60 trillion years, dying so another can be born anew as it was formed before.

All of this has happened before, and all of it will happen again, and again, and again.
