When the sun is a red giant, the earth will molt due to the sun's heat, and get sucked in the sun. Mars will become a dead planet with no atmosphere. Venus will be swallowed, Mercury Will be swallowed, Jupiter will larger in size and have a enchanted aurora. Saturn tempature increases and have a aurora. Uranus and Neptune will not change.

The sun rays all planets, transform into small star, and we go to heaven.

Well maybe according to caculations, the sun might get so big that earth gets sucked in THEN turns to a white dwarfs, then after that probably it will get sucked up by the nearest black hole.

The "gaining weight part" is wrong it'll only expand when it's energy gets low, and then collapse into a white dwarf
