Nature's cycle

For multiple years i had been growing vegetables on the vacant land next to my house and in last couple of years during this covid-19 pandemic i started to build small personal garden over there. I started to plant flowering plants and vines in my garden and big trees on my street. I observed that small colorful insects  and butterflies 🦋 became frequent visitor to my garden. To feed on these insects this year small birds 🐦 have started to come and as their numbers grow i expect medium size birds and then bigger ones will start to come, which will complete the natural cycle.

This brings an interesting thought that in nature for everything there is cycle, birth, growth and death. Death of one means life for another and its death in turn means life for someone else. This cycle of birth, growth and death could be as small as a day for some of the insects to hundreds of years for some animals like sharks to 1000s of years for some trees like some pine trees some of them are there on our planet for almost 5000 years. 

Along with living beings there is cycle for non-living things also, for e.g. H2O which is called water in its liquid form. Water get evaporated from Oceans/other waterbodies and become gas and then falls back on earth surface  as rain or snow and which in turns melt to become water to flow as water streams or rivers which makes life sustainable on earth.

Similar to these there are cycles of heavenly bodies including our earth or Sun which will live for few billions(10-15 billions) of years. Probably after few billions of years Sun will start to expand and start gobbling up Mercury, Venus or possibly Earth too ending life of these planets and one day as Sun consumes its hydrogen it will become a nebula and die a peaceful death. Life cycle of a star is 10-20 billions of years. Possibly our nebula will be consumed by some black hole in our galaxy some day, making the black hole bigger and over few hundreds/thousand of billions of years other stars in our galaxy will die and one day all the matter will be pulled in one giant black hole. In the mean time the other galaxies will continue to merge into each other under gravitational forces and most of the mass in our universe will become one super giant black hole, or you can find new name for it.

And one one fine day there will be BOOM, this giant black hole will forcibly explode and we will call it "NEW BIG BANG". All the matter from this giant black hole will be thrown away will too much force in all the directions, new billions of galaxies will be formed and over billions of years in each galaxy billions of stars will born and some star will have its planetary system and on one such planet we will born and we will see complete cycle of birth, death and rebirth ...
