How to make the sun a Red Giant!
« on: January 15, 2012, 01:40:02 PM »
Right, I don't know if you were wondering how but here it is anyway.

1. Click the sun
2.Change the Mass  to 0.50 suns.
3. Change the temperature to about 3000 K
4.Change the diameter to about 2 AU.

There you have turned the sun into a red giant, make sure your on edit mode or else the other planet will float away and it wont be able to show you what happens to earth in about 7.5 billion years.

Note: its important you do this in the right order.

Quote from: wikipedia
Sun reaches its largest size, despite the Sun losing about 38% of its mass.

If the sun loses about 38% which would be 0.62 suns on universe sandbox. I think 0.50 suns  is close enough. but that's what I think.

you can do 0.62 if want a more accurate simulation  :)

Wait what? A 12% difference is close enough??!!

yeah, i guess; this is pretty vague anyway. Who knows? maybe we'll chuck all the gas giants into the sun in the future to prolong fusion several thousand years while we come up with a permenant solution.

Don't we already have 7 billion years?

no; not in le future :)
suppose something sets us back in time and we dont have the technology
 

or our understanding of physics is horribly flawed and we were completely wrong

Besides isn't andromada coliding with the milky way in 4.5 billion years
yes, i believe its something more like 2 billion

i prefer to use the term "merge" rather than collide. Many people think that stars and planets from both galaxies will hit each other. this is not the case. Probably all the stars will simply pass through them. the solar system will most probably survive.
