Need something else to worry about?

I have learned a couple of interesting tidbits that caught my attention. If you are a natural born worrier you'll love this. If you are not the worrying kind you may find this just interesting, or not.

I learned our sun is dying. It's been around for some four billion years and has a life span of somewhere around ten billion years. That means the sun only has about six billion years of life left. When it starts to run out of fuel, it will expand into a giant red star. It will grow to 250 times the size it is now. Yep, you guessed it. We are in for real heat wave. If you think global warming is bad now, just wait until our precious earth is engulfed by our expanding, dying, sun.

If that isn't bad enough, there's another doozie of a calamity headed our way. The Milky Way Galaxy and the Andromeda Galaxy are right on target to collide in about five billion years. Talk about fireworks. However, space is so massive it is possible that our Earth might not get hit. But there will be enough chaos amongst the planets and suns of both galaxies, nothing will be the same ever again.

To the worriers I say, don't worry about it. We will have blown ourselves up with atomic weapons long before either of the above calamities happen.
