The Red Giants are evolved from main sequence stars. They are huge in size generally 4 to 6 solar masses. A red giant is a luminous giant star of low or intermediate mass that is in a late phase of its evolution, with nuclear fusion going on in a shell outside the core but not in the core itself. Red Giants are typically colored yellow to orange and to sometimes red. Red Giants are stars that contain way larger radii than the sun does. Thats Huge!!
A White Dwarf is a star that is exhausted of its nuclear fuel. A typical white dwarf is half as massive as the sun. Although it is only a little bigger than the Earth. White Dwarfs are one of the densest forms of matter. Some white dwarfs have almost all helium and hydrogen atmospheres. White dwarfs are said to have very strong atmospheres' as well. They are also known as the degenerate dwarf.
Our Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system mass. That's CRAZY. Solar energy is created deep within the sun's core. The Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so. At the end of its life, the Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will swallow the Earth. After a billion years as a red giant, it will suddenly collapse into a white dwarf. It may take a trillion years to cool off completely. Yeah a trillion years unless global warming takes over first. lol.
Black holes is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Some black holes spin around an axis, and their situation is more complicated. The surrounding space is then dragged around, creating a cosmic whirlpool. So far there are no signs of a blackhole near Earth. Thank God.. Either way black holes consume everything in sight, even light.
All of these are a part of our world today. I personally think that black holes are like the bully of society, you never want to cross one. We need the sun to exist and live. Without the red giant or the white dwarf the sun would not exist today. Overall the solar system and the galaxies are something so beautiful that it would be bad news for everyone if something went completely wrong. Say goodbye to life as we know it....

KERI! Where have you been? Nice post anyway. How was doing homework at HOME. Just kidding. 98% of the universe's mass really!

I loved your input about how important the sun is. I agree that nobody really wants to come across a black hole. They are scary.

Nice job, you have a great opinion especially on a subject that is often difficult to have an opinion on. The solar system is a very interesting, and important part of our lives, whether we will acknowledge it or not. It's amazing to think that the Earth is really just a small part of the overall picture. Again great post
Fabulously yours,
Megan
I really enjoyed reading your post because it was very well written. You explained everything very well and put it into terms you can understand. I enjoyed the fact that you put your personal opinion into your writing. I also liked how you included your hypothesis for what is yet to come.

You guys are definately getting the hang of this. As I said before, it is always a good idea to post your opinion in your writing. It makes the article your own. You comments were good. Great work.
