What if we will lost our sun?

So we all have imagined at least once what it will be to live on a planet without the sun.

while talking about a planet with no sun we are not talking about the absence of sun, natural lights but also talking about the effect of the sun explosion on our earth.

So let's start while we are talking about star explosion stars usually explode when they are fully grown and become Giant Stars but our sun is a dwarf star till the time it will become a giant maybe it will eat the planet earth. But if agree with the theory or this exception case that our sun will die young or we can say explodes now it will emit so much energy with a lot of pressure that will be enough to exploit our ozone layer which will lead to the destruction of atmosphere on earth. apart from natural destruction and damages tech-world and science will be also damaged all of our satellites will be destroyed no networks, no weather forecast, no communications, and no further hope to migrate to another planet this may take us back to the 18th century when there was no electricity and coal and oils were the only sources of power. but things will get worse when we will not have enough energy to dig out the sufficient amount we need and till that will be left with a limited amount which will be over in a decade or two. Burning wood might be fair enough during this situation of energy crisis but due to the end of the ozone layer, harmful UV rays will destroy plants as well so we are not left with plants, no ozone also means no oxygen remaining on earth that means we can not survive on this planet. This was if it happens now when our sun is a dwarf.

Let's talk about if our son grows up to the fullest and becomes a giant.

This will be the worst scenario humanity would have ever witnessed Sun will start growing second after second and slowly and steadily starts eating our neighbor planets starting from mercury and then Venus and then us but before the day sun will eat our human existence will come to end and earth being habitual will become history.

As I said above we will start losing our satellites and then the increase in temperature will lead to melting glaciers resulting in floods on the whole planet this will destroy transportation. Due to high-temperature flood water will start to evaporate and this will make humidity rise up to 100% and now during this, we will not have any ocean, sea, forest, oxygen, fuels this is what I call is hopeless death.
