  @sposadelvento @VoiceofDuum No. In about 5 billion years the sun's core supply of H will have been mostly converted to He via nuclear fusion that currently provides us with energy, & then the sun will expand to become a red giant with its surface just inside the Earth's orbit. At that point the core will engage in a He -> C fusion reaction. After a few hundred million years the core will be choked up with C and then it will collapse to become a white dwarf star. 1/3 #astronomicalTruths
