We get up every morning and experience the wonderful light from our sun. We take our medium-sized star for granted and usually don't take the time to think about its life-giving powers. The sun heats our planet, provides the energy for plants and animals to grow, and prevents the earth from becoming a cold, lifeless chunk of rock. It is reassuring to know that during our life time, and the life time of our children, and of their children, our faithful star will continue to shine and support life. However, in the distant future our world and our sun will die a violent death.
Our star, the sun, was born in the heavens about 4.5 billion years ago. Our sun is about 1/3 of the way through its expected life. Scientists are now predicting the following events during the remaining life of our star:
This will certainly be a violent end for our sun and the earth. This does not, however, mean the end of the human race. If our science and technology capability continues to advance, we may be able to explore and colonize other worlds. Home, for future humans, may be billions and billions of miles from our home world of earth.
