Sun will turn into a black dwarf star!?

Our Sun will become a black dwarf star that has cooled enough in order that it does not emit heat significantly - trillion years from now

As we all know the existence of life isn't possible without the sunshine and warmth from the Sun, through the tactic of photosynthesis the Sun alongside water and CO2, allows the plants to grow and therefore the carbohydrates in plants provide the first source of energy for humans and lots of other life forms.

Let's first get a brief glimpse of what Sun actually is, a hot ball of glowing gases its gravity holds the system together keeping everything from the most important planets to the smallest debris particles in space orbit.

electric currents within the Sun generate a magnetic flux that's administered through the system by the solar radiation, a stream of electrically charged gas blowing outward from the Sun altogether giving directions the interactions between the Sun and Earth drive the seasons, radiation belts, weather changes, ocean currents.

The Sun began to make about 4.6 billion years ago when a huge cloud of gas and molecular dust began to collapse because the cloud compressed gravity caused its particles to condense into distinct areas with most of the particles ending up in an orbit near what had been the centre of the clouds another thousand years passed in which the orbit continued to collapse until finally a combination of rising temperatures and increased pressure kindled its core after a few more million years of existence as a rowdy windblown the sun getting old with each unit of time passing.

Million plenty of hydrogen is converted into helium on the sun to get energy but the hydrogen may be a limited source and in about five to seven billion years it'll run out of fuel!, when it does, the Sun will burn to hotter and warmer a couple of billion years from now the Sun will burn so hot that it will begin to evaporate our planet's ocean unable to recover the widespread drought causing stress, the world citizenry is getting to be among the last to die first we'll witness the highest of flowers.

The Sun will burn too hot that photosynthesis will no more be possible to occur, hence without plants  (food), plant-eating animals will starve to death, meat-eating animals will become extinct thus without water, plants- animals and civilization will eventually die about 3.5 billion years from now, the Sun goes to be so large then hot that Earth's mountains would begin to melt at, now Earth's atmosphere would be more like that of Venus a remix of 96 activated charcoal dioxide and to a lesser extent, nitrogen and other elements after a few of more billion years of steeping during a hot slurry of CO2 and warmth earth is going to be swallowed by an ever-expanding Sun gobbling up the matter because it careens towards death.

After billion years from now, Sun would become a nebula, a nebula could also be an enormous cloud of dust and gas in space after nine to 10 billion years Sun will become a white dwarf star after it's exhausted all of its fuel, it expels most of its outer material creating a nebula and only the core of Sun will remain after trillions of years from now.
