Nothing you need to worry about. It will continue exacty as it does today
1. the sun exploding, but that will not happen for another billions of billions of years.....
overpopulation
yes , of corse the sun is older than 1000 years old because the earth is alot older then 1000 years!Answ2. The Solar system, Sol and the planets is approximately 4.5x109 years old.This may be established by radioactive dating methods.
No one knows what will happen. It would be conjecture to answer this opinion question.
about 55 years
Its falling and falling every years.
It will take millions millions of years for that to happen.
every four years an eclipse will happen because the moon is covered by the sun
it will happen soon
It is impossible to predict the distant future.
Chaos will roam the streets for 1000 years and then the end of time will happen after those years!
As a result of the Sun having more helium and less hydrogen left, it is expected to gradually get brighter, and larger - somewhere around 500-1000 million years from now, it will probably get too hot for any life to survive on planet Earth. That is, unless we do something about that.
