listen, little timmy needs to learn sometime
Raxiel, Don’t worry about the sun expanding to swallow earth! It will gradually get hotter as the core uses fuel and contracts, rendering earth uninhabitable within just 1b years (if we don’t beat it to the punch)
poweruser, The Earth is about 4.5 billion years old and the Sun will expand large enough to make the planet uninhabitable in about 500 million years.
In other words, the Earth is already 90% of the way through its life cycle.
Don’t worry though. We’ll almost certainly make it uninhabitable for humans long, long before that time
Engywuck, So strangely true… My son got scared a few years ago while watching a documentary about black holes and the death of the Universe.
stebo02, 
tbh that is kinda scary, just for different reasons

I have to wait six billion years for this place to get what it’s got coming?! We need to put this shit on fast forward

I thought we did.
Zink, I had this exact conversation a few days ago, and my kid is even 6!
siipale,
shneancy, wow your kid is 720? no wonder he’s scared he might live to see it!
alcoholicorn, It’s not gonna explode though, it’ll slowly grow until it reaches out to the outer planets, then collapse into a white dwarf that will slowly cool for eons.
Neato, 
It's red or orange giant phase might get to earth. It won't get any farther though.
CarbonIceDragon, 
On the bright side, that’s plenty of time to do something about it
