the future of our planet depends on it ?

time is flying by
yet the arc of human life is  getting longer
65 years is the global average ,way up from just 20 in the stone age
modern science however makes our lives just a blip in the life of our universe
charles darwin says earth evolved in an evolutionary  process
but the processes that shape a planet like ours only  plays the smallest of roles  in the evolution of the cosmos  
so to glimpse time's broadest of arcs we must look at the universe beyond
the reigning theory says it all started in  space in a bang bang billions and billions of years ago
seconds after it happened it  set  in motion  what these sciences call the primordial era
an era when over a period  a heated soup of atoms cooling ballooned outwards , then growing dim and forming into what
is called the cosmic  dark age
for several hundred million years later gravity was daily working to pull particles together
so that considerable lumps of matter had drawn together
these pockets of gas particles became dense enough  to heat up and then ignite
beginning the era of the stars
the life arc of this great era of stars is defined by the life cycle of these stars
which vary according to their sizes
stars  shine because gravity crushes matter into their cores
releasing energy pushes  outward and balances the inward force of gravity
In large stars gravity gains the edge and tips the balance and the star collapses
in on itself , the energy released causes the star to explode
in a blast of light and debris that's visible  across the cosmos
this is likely what is  in store for our sun
Martians, Venusian or plutonium civilizations  may one day in distant
time scan the sun for planets but they wont see earth
due to the rising solar  luminosity which gradually  blasts away
earths atmosphere rendering it uninhabitable
water will  disappear evaporated by the heat and striped off by solar winds
finally as the sun blows off its outer layers they will envelope the earth
the friction and heat melting the earth into its sun
now  the universe is looking like a place where gravity and energy have forged an extended truce
we find  such places as brown drawfs because these burn so slowly they will be the final beacon of stars
an era that will extend out to one hundred trillion years the degenerate era
around a billion billion billion billion years later after it all began all the protons in the universe
it is expected they will slowly degrade turning back into sub atomic particles that decay into photons , particles of light
their decay marking the end of the degenerate era
we dont know what will happen after that as this moment in time

Re: the future of our planet depends on it ?

If it is seriously an English essay; then it gets a great big fail from me.  Whilst it is interesting reading; the lack of punctuation means that it fails.
