Do we have to worry? Is the sun going to explode before we die?
Answer 1:

You don’t have to worry about the sun exploding. Our sun formed about 4.5 billion years ago, and will continue to be almost unchanged for another 5 billion years (that’s a LOT of time!!). It still won’t explode then, rather it will grow bigger and brighter when its fuel source- hydrogen depletes. Only after 6 billion years from now, will it even think about exploding.

There are many other possibilities that could hurt or is hurting us and other life on planet. Global warming is being discussed a lot. An exploding sun should be the least of your worries.

Keep asking questions, learn more, and act, but never worry.

Cheers,
